Laowa Proteus 28mm T2 2x Anamorphic Review

R520240130 154647

The Laowa Proteus 28mm T2 2x Anamorphic lens was first shown at IBC 2023 last year. It is currently the widest lens in the series, but there is still a 20mm still to come.

I have previously done an in-depth review of the 35mm T2, 45mm T2, 60mm T2 and 85mm T2 and you can see that review here.

R520240130 154836A

The Laowa Proteus 2x Anamorphic series cover Super 35 sensors and all the currently available lenses are T2. The Laowa Proteus 2x Anamorphic series will eventually consist of 8 lenses:

  • 20mm T2*
  • 28mm T2
  • 35mm T2
  • 45mm T2
  • 60mm T2
  • 85mm T2
  • 100m T2
  • 135mm T2*

The 28mm and 100mm haven’t started shipping yet, but they should be available to purchase soon. I don’t have information yet on when the 20mm and 135mm will be officially announced.

*We are unsure at this stage if the 20mm and 135mm are T2.

We first saw a prototype of the 28mm T2 at IBC and you can see my interview with Laowa above.

Proteus Series Overview

At under $5,000 USD each, you may not classify the Proteus lenses as affordable, but for 2x anamorphic lenses, they are very affordable. To put the price in perspective, the Atlas Orion 2x anamorphic lenses cost from $8,999 USD up to $14,995 USD depending on the focal length. The new DZOFilm Pavo 2x anamorphic lenses are slightly more expensive at $5,499.00 USD each.

All of the Proteus series lenses will cover an image circle diameter of 25.92mm x 21.6mm.

Laowa Proteus 03

On certain cameras when shooting open gate you will get some vignetting at the edges of the frame with the wider focal lengths, but if you are framing for 2.39:1 then that disappears.

Laowa Proteus 2x Anamorphic Series 55

For this review, I will be looking at the 28mm silver flare version.

Proteus Series Overview

Laowa states that the Proteus 2X Anamorphic Series was designed to be the most accessible professional anamorphic lens for Super35 sensors that features a constant 2X squeeze ratio. The Proteus Series is said to exhibit classic anamorphic characters with modern image quality.

R520240130 154846

The lenses are claimed to feature smooth elliptical bokeh and signature flares including blue, amber, and silver options.

R5B 20230619 181529

With 8 lenses already announced you don’t have to worry about buying a lens and then wondering if any more focal lengths will appear.

R520240130 154637A

I think it would be fair to say that Laowa is trying to attract owner/operators of mid to high-end digital cinema cameras that are capable of shooting in open-gate anamorphic modes. In saying that, there is no reason why they wouldn’t also find themselves in a lot of rental houses.


The lenses are available in PL mount, but they also come with a user-interchangeable EF mount.

Key features

  • Patented anamorphic design
  • Constant 2X squeeze ratio
  • T2 Large Aperture
  • Outstanding sharpness
  • Close focusing distance
  • Pleasant oval bokeh
  • Amber, blue & silver flare colors
  • Low Focus-breathing
  • User-friendly cine housing
  • Full-frame coverage with 1.4X expander

Size & Weight

The Proteus lenses are not lightweight and compact lenses. The 28mm T2 2x weighs 2.5 kg / 5.51 lb.

Below you can see what all the other focal lengths weigh:

28mm T22.5 kg / 5.51 lb
35mm T22.4 kg / 5.29 lbs
45mm T22.4 kg / 5.29 lbs
60mm T22.3 kg / 5.07 lbs
85mm T22.95 kg / 6.5 lbs
100mm T2
Laowa Proteus 2x Anamorphic Series 54

The 28, 35, 45, and 60mm all have very similar weights. the 85mm is pretty heavy at just under 3kg.

Laowa Proteus 28mm T2 3427

While you could use them on smaller-sized digital cinema cameras or mirrorless hybrids, the lenses are certainly better suited for use with mid to large-sized digital cinema cameras.

Laowa Proteus 28mm T2 3374

So how does that weight of the 28mm T2 compare to the Atlas Orion 28mm T2.2 and the DZOFilm Pavo 28mm T2.1. Well, below you can see:

Laowa Proteus 28mm T22.5 kg / 5.51 lb
Atlas Orion 28mm T22.8 kg / 6.2 lb
DZOFilm Pavo 28mm T2.11.2 kg / 2.6 lb

As you can see, the weight of the Proteus is fairly comparable to the Atlas Orion, but a lot heavier than the DZOFilm.

Build Quality

The 28mm T2 is just as well made and constructed as the other focal lengths I haver used.

Laowa Proteus 28mm T2 3377

The lenses feature a rather understated design which I personally like. They don’t draw attention to themselves.

R520240130 154828

What I am always looking for when it comes to sets of lenses is how consistent the mechanics and look are. Good lenses maintain very high levels of consistency across the focal ranges. With a lot of the more ‘affordable’ lenses that I have reviewed over the years the thing that normally lets them down is consistency when it comes to the mechanics, build quality and look. If you are a lens manufacturer and want a seat at the big boys’ table then you need to be able to deliver lenses that have consistency.

R520240130 154724A

The mechanical consistency of the Proteus 2x Anamorphic lenses across the range is pretty good. The 28mm T2 has very nicely weighted and smooth aperture and focus rings.

Laowa Proteus 2x Anamorphic Series 45

The focus resistance is pretty consistent across all of the focal lengths, except I did find that it was a little stiffer on the 85mm.


Unlike a lot of lenses coming out of China, the Laowa Proteus 2x Anamorphic Series don’t have focus markings in both feet and meters. The lenses are available in either feet or meter markings depending on what you require.

The markings are easy to see and I especially like the clear and concise red marking that lets you easily see exactly what T stop or focus distance you are at.

Back Focus Adjustment

One of the nice features of the Proteus series is that they feature a back-focus adjustment.

Back focus, which can also be referred to as focal flange length, is the distance between a camera’s sensor and the rearmost element of the lens. Adjusting back focus is especially important if you are changing over lens mounts. Usually, this is done through the painstaking task of using shims. I would highly recommend that if you have to use shims to change the back focus on an anamorphic lens, take it to a lens technician at a reseller/rental house. Adjusting the back focus shim stack on anamorphic lenses will adversely affect the optical performance and introduce astigmatism to the lens.

Laowa Proteus 28mm T2 3395

Instead of having to do this with the Proteus series you can use the back focus adjustment on the lenses to do this instead. This is as simple as loosening the lever on the back of the lens.

The best way to adjust back focus is to put your camera on a tripod so that it won’t move around. Then frame up a focus chart or any solid object if you don’t have access to one. Now the distance at which you place your focus chart away from the lens depends on the focal length of your lens. If it is a wide focal length, then 6′ / 183cm or so will usually work. If you are using longer focal lengths then that could be up to 20’/ 6m.

It is important that when doing a back focus adjustment that the lens you are using is wide open. In the case of the Proteus lenses, you want them at T2. If you have an EVF or monitor, it’s best to turn down the brightness and turn up the contrast so you can clearly see what you are doing.

Laowa Proteus 28mm T2 3421

You then focus the lens until it looks as sharp as it will get and then you loosen the back focus and adjust it till you get the sharpest image. Once you have done that then you tighten up the back focus, but you need to make sure that you don’t move it when you do this.

Anamorphic Design

Screenshot 2023 01 18 at 12 40 37 AM

The Laowa Proteus 2X Anamorphic Series features a front anamorphic design.

Optical Construction

Laowa Proteus 28mm T2 3384

All the focal lengths feature 10 aperture blades. The 28mm has 17 elements in 15 groups.

The 35mm and 45mm have 17 lens elements in 14 groups, the 65mm has 17 lens elements in 13, and the 85mm has 18 lens elements in 13 groups.

Constant 2X squeeze ratio

The 2X squeeze ratio allows you to create the classic wide-screen anamorphic look and it pairs well with 4:3 or 6:5 sensors which are usually defaulted in professional cinema cameras to deliver a 2.66:1 or 2.4:1 image after de-squeeze. You can also crop to a 2.39:1 with minimal loss of resolution.

With the optical design, the 2X squeeze ratio can be achieved at any focus distance. Laowa also states that the lenses maintain the relative shape of the object and avoid anamorphic mumps. I will test this further down in the review.

The iris ranges from T2 to T22 for the entire series.

According to Laowa, the optical performance has been fine-tuned to deliver excellent color rendition and contrast.

Close Focus

Below you can see the minimum focus distance for the Laowa Proteus Series below:

Minimum Focus Distance
28mm T21.57′ / 48cm
35mm T21.8′ / 55 cm
45mm T21.8′ / 55 cm
60mm T22.3′ / 70cm
85mm T22.7′ / 82cm
100mm T2NA
Laowa Proteus 28mm T2 3441

How does the minimum focusing distance of there 28mm T2 compare to the Atlas Lens Orion 28mm T2.2 and DZOFilm 28mm T2.1? Below you can see:

Minimum Focus Distance
Laowa Proteus 28mm T21.57′ / 48 cm
Atlas Orion 28mm T21.5′ / 45 cm
DZOFilm Pavo 28mm T2.11.4′ / 42.6 cm

Flare Options

As I mentioned earlier, the lenses are available in either blue, amber, or neutral silver flare color options. If you are looking for something with a more neutral flare then the silver flare option will change color according to the light source.

Other Features

All of the lenses feature unified gear positions so that they can be switched quickly between focal lengths to work with the same set of gears.

Screenshot 2023 01 18 at 12 43 24 AM

They also all have a Back focus Adjustment Mechanism that I mentioned earlier in the review so that you calibrate the back focus with the lens mounted on the camera directly without going through a tedious shimming process.

Screenshot 2023 01 18 at 12 44 48 AM

The lenses feature a Ø 114mm outer diameter and a Ø 105mm filter thread.

Why were anamorphic lenses made?

What you may not know is that anamorphosing optics was developed by Henri Chrétien during World War I to provide a wide-angle viewer for military tanks. The optical process was called Hypergonar by Chrétien and was capable of showing a field of view of 180 degrees. After the war, anamorphic lenses for cinema were originally designed so that wide format imagery would fully utilize the film area of a standard 35 mm frame. The lenses also enhanced vertical resolution and reduced the appearance of grain. The technology was first used in a cinematic context in the short film Construire un Feu in 1927 by Claude Autant-Lara. The introduction of the Super 35mm format made the difference between anamorphic and spherical lenses a lot less obvious. This is because Super 35 provided more horizontal film area, as it didn’t have to record the audio next to each frame, as was the case with standard 35mm film.

Why shoot anamorphic?

Laowa Proteus 2x Anamorphic Series 52

With a lot of anamorphic lenses, you are going to see image imperfections, but this is what makes anamorphic lenses so special. With modern-day cameras and sensors being so good, a lot of DPs want to try and add character through the use of vintage or/and anamorphic lenses. Image characteristics when shooting with an anamorphic lens include the bokeh taking on the appearance of being oval-shaped as opposed to circular, and flares appear as bluish horizontal or vertical streaks which can span across the entire picture. The other characteristic associated with anamorphic shooting is the widescreen aspect ratio.

Laowa Proteus 28mm T2 3424

If you are working in HD or 2K formats with spherical lenses, you could just crop your 2K frame to get a 2.39:1 ratio, right? Yes, you could, but the problem is you are left with just 858 lines of vertical resolution. Anamorphic lenses provide a way to capture a 2.39:1 ratio without having to make that sacrifice in resolution. Of course, you can also capture at higher resolutions (4K, 6K, 8K, etc.) and then deliver in a lower resolution as well.

Screenshot 2024 01 29 at 11 10 10

2x anamorphic lenses produce a super-wide 3.55:1 ratio. To produce a traditional 2.39:1 ratio with a 16:9 sensor, a 1.33x or 1.35x anamorphic lens is needed.

Anamorphic certainly isn’t for everyone

As the old saying goes, just because you can, doesn’t mean you should. Anamorphics aren’t for everyone and they certainly aren’t suitable for a lot of projects. The very nature of their aspect ratio makes them difficult to use for a lot of content you may want to shoot. TV broadcasters often want a native 16:9 aspect ratio as they don’t want to have black bars below and above the image shown on their viewer’s screens. A lot of DPs would love to shoot anamorphic or even in a wider aspect ratio, but this is normally vetoed by the network. Because the anamorphic-scope camera format does not preserve any of the images above and below the scope frame, it may not transfer as well to narrower aspect ratios, like the commonly used 16:9 for full-screen television.

R520240130 154700

You also need to take into account that the depth of field is also affected when shooting anamorphic-ally. Technically anamorphic and spherical lenses have the same depth of field, but in real-world use, you have to use a longer focal length with an anamorphic in order to achieve the same angle of view. This means at the same magnification (for example using a 35mm focal length), anamorphic lenses produce a shallower depth of field. As we all know, (whether you agree or not) the “cinematic” look is often associated with a shallower depth of field.

Reasons for not shooting anamorphic can include:
* Most anamorphic lenses can create artifacts or distortions
* Generally more expensive than spherical lenses
* A lot of anamorphic lenses are slower than spherical lenses and require more light
* Does not transfer well to narrower aspect ratios, such as 16:9


I was surprised by just how sharp the 28mm T2 was. With most wide 2x anamorphic lenses tend to be soft, especially when used wide open.

For a 2x 28mm T2 anamorphic lens the Laowa provides a nice amount of sharpness, and it is certainly usable even when used wide open at T2 . Stopping down to T2.8/ T4 certainly offers improvement. The edge sharpness is also impressive.

Below you can see sharpness tests for some of the other focal lengths in the series.

The Laowa Proteus lenses are reasonably sharp for 2X anamorphic at this price, but with some of the focal lengths, they can be a little soft when shooting wide-open at T2, however, you really need to zoom in a lot to see that softness. Once you start stopping down to T2.8-T4 they do sharpen up. I would say T4 to T5.6 is the sweet spot for sharpness.

R520240130 160858

They are certainly a little softer out towards the edges of the frame, however, I personally thought that the sharpness drop-off wasn’t as big as I expected.

The wider focal lengths do suffer from some pincushion distortion, however, it isn’t too bad. If you are not familiar with pincushion distortion it is where straight lines bend or pinch inward from the center of the image. You will sometimes see pincushion distortion in images with straight lines, especially out toward the edges of the frame. The further the lines are away from the center of the image, the more noticeable the distortion. Pincushion distortion isn’t necessarily a bad thing with anamorphic lenses because if you are doing close focus with a wider focal length, you don’t want to have barrel distortion as that would make people’s faces look distorted.

R5B 20230619 183901

The 45mm and 60mm are arguably the sharpest out of all the lenses I have tried, and even at T2 they retain a good amount of sharpness when compared to the 35mm and 85mm.

R520240130 154939

In technical tests, the Proteus is not going to win people over, but that’s true of a lot of anamorphic lenses. Technical tests are more unforgiving than a lot of real-world shooting situations and they are done to look very closely at potential optical flaws. Zooming in 300% on an image is not something I am ever going to do in the real world, it is just pixel-peeping.

R520240130 155823

In the real world, most lenses are going to look a lot better than they will in technical tests. The reason I do tests like this is it gives you a benchmark when comparing other lenses. The robot has a very fine pattern on its surface and this is very helpful in seeing sharpness, detail, micro-contrast, etc.

Lens Breathing

I tested out the lenses by doing large focus throws and there is certainly breathing in the form of vertical stretching when using the lenses wide open, but for 2x anamorphic lenses at this price, that is to be expected. If you stop down to T5.6 the breathing is minimized.

Anamorphic breathing appears in a different way than when using a normal spherical lens. With a spherical lens, breathing gives the appearance that the focal length is changing. However, with anamorphic lenses, vertical stretching occurs with the background. So when you adjust focus from something close to something further away, the background takes on a squeezed appearance. Hence why you see oval instead of round bokeh.

With anamorphic lenses, the more you stop the lens down, the less the out-of-focus object’s appearance will change. If you shoot wide open and pull focus the out-of-focus objects will change shape more dramatically.

Older anamorphic lenses such as Lomo’s and Kowa’s can breathe a lot. Newer anamorphic designs from companies such as Zeiss and Cooke have a lot less breathing. The popular Panavision E Series anamorphic lenses retain true anamorphic artifacts such as disproportional vertical focus breathing.


Let’s face it, the reason a lot of people want to use anamorphic lenses is because of the interesting flares you can obtain. Yes, they can be overly used, and sometimes less is more, but the probable target audience for these lenses is arguably looking for nice subtle streaks.

Used wide open, or relatively wide open, you do get quite a nice diffused and soft streak. There is some veiling which I personally liked, but it may not be to everyone’s taste.

The lens I was testing was the silver version so the flares take on the appearance of the light source. Whether you prefer a blue streak, amber streak, or a more neutral steak is again a personal thing.

A strong blue streak might be fine if you are shooting a Sc-Fi movie, but it can be very distracting for a lot of other content. Sometimes less is more.

Personally, sometimes I like to use lenses like these in combination with something like glimmer glass to further soften the streaks.

Below you can see flare tests with some of the other focal lengths in the series.

The lenses maintain reasonably good contrast when a lot of direct light is shining down the barrel.

Chromatic Aberration

The 28mm does show signs of chromatic aberration when used wide open and at T2.8. You can get some slight purple fringing, but generally, it is well-controlled.

Above you can see 300% crops at T2.8 and T4 with the 65mm T2. As you can see there is purple fringing in high-contrast areas even at T2.8. You have to stop down to T4 to avoid seeing any.

You will also clearly see this in my test footage further down in the review.


Oval-shaped bokeh is another drawcard of anamorphic lenses. The ability to create interesting-looking out-of-focus areas can certainly be used to help to enhance a shot. I personally prefer out-of-focus areas in the foreground rather than the background when using lenses like this.

The bokeh is what you would expect for 2x anamorphic lenses with a T2/T2.8 aperture. It has that nice oval appearance.

Real World Use

I took the 28mm T2 out and shot some quick test footage so that you could see the general look and characteristics of the lenses. The footage was cropped for 2.39:1.

R520240130 155001A

I really like this lens and I like the wide focal length. It has a nice balance between sharpness, optical performance, and character. You can get nice flare with strong light sources, but isn’t over the top.

Above you can see test footage taken with some of the other focal lengths.

R520240130 155019

The mechanics of the lens make it easy to use and it certainly provides you with that ‘look’ that you would typically associate with a 2x anamorphic.

The Proteus series is perhaps a little more clinical than some other options on the market, but you know what, I hardly think that is a negative. They can easily be used wide open at T2 and T2.8 as they provide good levels of sharpness, which is something other anamorphic lenses struggle with. Sharpness does improve when you stop the lenses down, and you do need to be aware of the chromatic aberration when using the lenses wide open.

Do they match?

R520240130 155113

With some of the ‘affordable’ anamorphic lenses on the market, the look and build quality between focal lengths can vary quite dramatically. It was nice to see that the build quality and general look of all the lenses remained consistent. If you are going to buy a set of lenses, you want them to match as closely as possible.

Can you get wide enough?

R520240130 155736

With the widest focal length currently being a 28mm, you may well be asking, is that wide enough? A 28mm 2x anamorphic lens has the equivalent field of view of a 14mm lens. What you do need to remember is that you are getting a 14mm horizontal field of view, but you are losing information vertically. Wide angle anamorphic lenses of less than 40 mm focal length produce a cylindrical-perspective which some people like, and others hate.

With the upcoming 20mm, you will certainly be able to get an extremely wide field of view.

Price & Availability

Laowa Proteus 28mm T2 3443

The 28mm T2, just like the rest of the Proteus 2x anamorphic lenses retails for $4,999 USD per lens and a 2-lens set is $9,499 USD.

Screenshot 2023 06 21 at 11 07 01 PM

The closest competition, at least in my opinion, comes in the form of the Atlas Orion series and the DZOFILM PAVO 2x Anamorphic Prime Lenses.

You could also argue that the Atlas Mercury series could also be considered strong competition.

Laowa Proteus 28mm T2 3432

So how does the price of the 28mm T2 Proteus compare to other options on the market? Below you can see:

Laowa PROTEUS 28mm T2$4,999 USD
Atlas Lens Co. Orion 28mm T2$9,995 USD
DZOFilm PAVO 28mm T2.2 2x$5,499 USD

The Laowa Proteus series certainly offer very good value for money given their optical performance and build quality.

Do you really need an anamorphic lens?

R520240130 160647A

I think in principle a lot of people like the idea of shooting with anamorphic lenses, but whether or not you actually need to is maybe a completely different story. Depending on what you do there may well be little to no demand to shoot anamorphic. For a lot of shooters, it makes more sense to rent anamorphic lenses rather than to own them, however, with quite a few budget-friendly options now on the market, they are affordable enough to purchase. The Proteus series certainly fits that bill, especially for owners of mid to high-level digital cinema cameras.

R520240130 160815

While you may find the look of anamorphic esthetically pleasing, in the past, a lot of shows would not shoot anamorphic for broadcast television, simply because the broadcasters don’t want viewers complaining about black bars on top and below the image.

However, with more and more online content being created by Netflix, Amazon, Disney, etc. this isn’t really an issue anymore. Online streaming entities are often more than happy to have productions shoot with anamorphic lenses and the 2:1 aspect ratio has become an increasingly popular delivery format for Netflix. If you produce content that will end up in a widescreen aspect ratio you could easily mix anamorphic and other spherical lenses together. Also if you are making your own content then go for your life and use whatever you like.

In my honest opinion, it can be better to just rent good anamorphic lenses for projects that require them. Although, in saying that, buying affordable anamorphic lenses makes sense if you are someone who is going to use them a lot for the type of work you do. The Proteus series is sure to appeal to both owner/operators and rental houses.


R520240130 155042

I really enjoyed using the 28mm T2. It is very well made, has solid mechanical operation, and most importantly it produces nice results.

I was pleasantly surprised by the Proteus series because I wasn’t the biggest fan of the more affordable Nanomorph anamorphic lenses that Laowa also makes. The Proteus series feels like a more serious effort at producing proper cine anamorphic lenses. They are very competitively priced for 2x anamorphic lenses, and at this price point, they don’t have any real direct competition.

In the past, I have generally been pretty disappointed with most so-called ‘affordable’ anamorphic lenses, although there have been some exceptions. The trouble was those exceptions were plagued by inconsistencies with the look, build quality, and mechanics.

The Proteus series is well made, and despite a couple of niggling complaints, (I am being pretty picky here) in regard to the mechanical consistency, they are far and away a lot better than anything else I have seen or used when it comes to anamorphic lenses that cost under $5K each.

They certainly punch well above their weight and I think Laowa has done a very good at coming up with 2x anamorphic lenses that I think a lot of people will like.

Anamorphic lenses are hard to review. Sure, I can talk about the technical aspects of a lens, but technical perfection is not what most DPs look for when choosing an anamorphic. The character and unique look of a lens are why certain anamorphic lenses are more popular than others. Unless you are after something that is super clean like an ARRI Master Anamorphic, the preference is usually to find and use a lens that has lots of character. The Proteus series is what I would describe as modern anamorphic lenses. They don’t have tons of character, but in saying that, they aren’t too sterile either. I really hate using the word character, because what does that actually mean? There are a lot of instances, although this does depend on the type of work you do, where having lenses with ‘character’ is not going to suit the project. I personally prefer to use cleaner lenses and then alter them with filters or in post, but that’s just me. Everyone has different needs and requirements and there is no right or wrong choice. Having a cleaner looking anamorphic can also help if you need to mix and match it with spherical lenses.

In the past, anamorphic lenses were predominantly rental items for a lot of shooters, simply because the cost of ownership was so high, but over the last 3-4 years a lot of affordable options have come to market. I can see more and more people starting to purchase anamorphic lenses instead of renting them.

Lenses can have different characteristics when used on different cameras and it is important to try out both the lens you want on the cameras you own or use.

R520240130 155718

The Proteus series strikes a very good balance between affordability, image quality, and consistency. It is great to see another company bring out 2x anamorphic lenses when the trend is to go with 1.5x or 1.8x.

The 28mm T2 is a great addition to the series.
