Micro Four Thirds ENG servo zoom

Recommended Posts

Posted (edited)

When Blackmagic released the Studio Camera (back in 2014, if I'm not mistaken), I felt it was a terrible decision to use a Micro Four Thirds lens mount, because the lens selection was terrible for the application. There were and are no MFT servo zooms, which basically knocks the Studio Camera out of the running. I've only ever seen a single unit out in the wild. Sure, you could use a B4 adapter and hope the lens has a doubler, but that's less than ideal from an optical standpoint.

Five years later, there are still no MFT servo zooms. In the meantime, Blackmagic has released the Studio Camera 2 in HD and 4K, two models of Micro Studio Camera, and the Pocket Cinema Camera 4K (which is now being advertised as an ideal unit for multi-cam in coordination with the ATEM Mini), all of which have a MFT mount. Consider also the Z Cam lineup and the fifty billion other MFT cameras that do video.

There are a number of Super 35 zooms, so it seems to be possible. Canon has the cine-servo lineup. The Fujinon MK lenses are available in MFT, but they lack a first-party motor and are designed for S35.

Am I crazy? Or is this actually a legitimate product category that has yet to be addressed? I just want to be able to take a GH5 or E2 and work as fast as I do with a 2/3" ENG cam.

Hey Guiseppe,

The lens adapter company MTF made an adapter so you can use B4 lenses on the Super16 sensor of the Studio Camera without using the extender: MTF B4 2/3" to Super16 Micro 4/3 Adaptor

If you would like to use Super35 zooms (with EF mount) on the Pocket 4K look into this Metabones adapter: Metabones Canon EF Lens to BMPCC4K T CINE Speed Booster® ULTRA 0.71x It allows you to use S35/APS-C lenses on the MTF sensor of the Pocket4K.

True, there are the adapters, and they work alright. But that's not really what I'm looking for. I want Fuji or Canon to release a servo zoom with a native 4/3" image circle. Obviously if you want a large zoom range, you have to either have a huge lens or a small image circle; that's one big reason why ENG still relies so heavily on 2/3" cameras/lenses.

To me, Micro Four Thirds seems like the perfect "large" format for ENG:

  • The dimensions make for an easy conversion from 2/3" to 4/3" using a lens's built-in doubler
  • Short flange distance adds flexibility in adapting from other lens mounts
  • Still fairly easy to pull focus on; definitely easier than full frame/super 35

Obviously there are additional concerns to be addressed. But I think the concept is solid and that there would be an audience for such a thing.

Honestly, I don't see it happening.  The market for a true MFT ENG lens like a 2/3" ENG lens is too small for Canon or Fuji to be bothered with it.  And even though there may be a lot of MFT cameras in the wild, there aren't enough customers with those types of cameras willing to spend the money.  Most people that want/need that performance are either using actual 2/3" cameras or s35 cameras.  I understand MFT has a loyal and devoted following, but it's kind of a bastard professional format.

    • Looks good Steve! I still have my F3 that I bought back in 2011. It was a very underrated camera and it is now a bargain if you don’t require 4K.
    • Evening all, Came across this page by chance and thought I would chirp up as a new PMW-F3 user. I'm a long time staff and then freelancer working in the UK for 41 years on broadcast news, on XDCam EX since about 2012. My son's followed me into the game and as I do less for TV and more and more web stuff, I gave him my kit and looked for something a bit more er, compact. Initially I was using a C300 for the occasional regional BBC day and sailing features and web adverts (I'm refitting a 45 yr old yacht for retirement). I had a couple of Nikkors converted to EF mount and de-clicked, a 16-35/2.8 and 70-200/2.8, and I used an EF 24-105 for run-n-gun. All okay, but I hate the C300 form factor and all those buttons just got on my man-boobs! Looked for something more viable and stumbled across the F3. Managed to grab one for 800 quid off eekBay and got very lucky: the thing was unmarked and had only 147 hours on the clock. Had it a few months now and it really has grown on me. The menus I'm familiar with obviously and don't mind their foibles. I shot a sailing doc in S-log for the first time recently, and it's due out in December so I'll put a link up in due course. I've perfected my setup (see pics) and what I like about this is that I can do all the things a proper shoulder camera can do, and then break it down into the simplest, lightest, setup for stumbling about a foredeck with one hand on the camera only. I'm a bit of a fettler, so you might notice a few things. Viz: built-in viewfinderectomy. Custom mount for the Alphatron 035 VF (which I love using). Power via a Hawk-Woods V-Lock adapter plate meant for an FS5 - only needed the output lead swapping for a 4-pin XLR to go into the F3 - that Alphatron is a power-grabber. Custom extension bracket from the Tilta baseplate to the Movcam wooden grip (another eBay bargain for 50 quid) although the record button is non-functional as of yet with no LAN port on the F3. Custom bracket to get the right height off the baseplate for the Vocas matte box and rails. I think I spend more time building this stuff than actual filming these days! Very pleased with it all and giving 35M/bit in the camera, still fine for local BBC, not that anyone asks. I gave my Black Magic Video Assist to the lad, but I'm highly unlikely to get called on for high end broadcast. No 444 key installed but no biggy. For quality web production and some news squirting, the camera is great, and I will be playing with this for hopefully a few years yet. FX6? FX9? Nah, sod that for a lark. Happy as Larry here 😉 Cheers, Cotty (Steve Cottrell)
    • I LOVED my F3! The only reason I left it behind was 4k--which 3 years later, almost no client has ever actually finished in. (Feels like wasted money.)   I have never loved a SONY menu, but the F3 was somewhat sensible. And the 4:4:4 color. But the thing I miss most was the highlight rolloff, it always looked right--really filmic. I'm kind of a Canon fan-boy now, but I struggle to make C200 raw lite fall off quite the same way. I'm hoping the new Sony sensors regain some of this highlight love, but I haven't seen it yet. LONG LIVE the F3!
    • I don't think it should be so much about which one might produce better, or equal, quality results, but more about usability and functionality. While I'm sure that the iPhone will produce great results, even my Redmi Note 9s (an ancient phone by comparison) does a pretty good job (especially using FiLMiC Pro), but I simply couldn't go about using a phone as my sole camera. I've seen how some of those iPhone videos have been produced and the phone is fully rigged up like a cinema camera. Many think that it's simply someone holding nothing but the phone. The devil is always in the detail.
