BIRTV 2015: Aputure DEC Pro Canon EF to M4/3 or Sony E mount focal reducer with wireless control

By Max Duncan and technical editor Matt Allard:

Aputure have shown a new version of their DEC lens adapter called the DEC Pro. The original DEC allowed you to remotely control focus and change the iris when using Canon EF or EF-S Autofocus lenses. The DEC adapter itself enabled you to use these lenses on a Micro Four Thirds or Sony E-Mount camera. This was a clever solution as the camera itself can’t communicate with the Canon lenses. To overcome this, an included wireless remote allows you to change iris (aperture) and drive focus from up to 328 ft away.

The DEC Pro is a similar lens adapter that has the added advantage of being a focal reducer or “speed booster” that offers a 0.7x wider field of view and gives you an extra stop of light. The DEC Pro version is likely to be of interest to users of cameras such as the Panasonic GH4, Blackmagic Pocket Cinema Camera, Sony A7R II and JVC GY-LS300. The adapter body itself is now two parts and not one. The optics and lens adapter can be detached from the wireless control for easier storage. The shape also means that it will fit more easily onto smaller brushless gimbal setups.

The remote control handgrip looks similar to the original version and can be mounted to gimbals or shoulder rigs in place of a regular handgrip. It has a display that indicates the status of the lens.

The DEC Pro kit, which consists of the adapter, controller and wireless remote is expected to be on sale very soon.

BIRTV 2015: Anamorphic options on the Convergent Design Odyssey 7Q+ demonstrated

By Max Duncan and technical editor Matt Allard:

With anamorphic shooting becoming very fashionable many users have been looking for ways to shoot the format easily. At BIRTV in Beijing, Mitch Gross from Convergent Design ran through the latest features for anamorphic shooting available on the Odyssey 7/7Q and 7Q+ external 4K recorders. These have advanced options for viewing and recording an anamorphic image when hooked up to the modern 4K cameras like the Sony a7S and Panasonic GH4.

The latest options include additional anamorphic de-squeeze settings and a centre extraction mode. The centre extraction mode de-squeezes and magnifies the centre portion of image, transforming wider letterbox footage into the more common anamorphic formats for viewing – this replaces having to tape off parts of your screen to adjust for the aspect ratio. The adjusted image is sent to video outputs but the recording itself remains unaffected.

Mitch also shows how the anamorphic functions can be used with the Hyper Zoom mode, peaking, false colour,waveform and vectorscope functions. These features make the 7Q+ well suited to Anamorphic shooting.

It also features a new quick release plate so you can get the camera on and off the gimbal a lot quicker, something that was missing on the original. There are three different profiles you can choose from when using the gimbal as well as an integrated joystick control to move the camera independently.

BIRTV 2015: Aputure A Lav lapel microphone for just $30

By Max Duncan and technical editor Matt Allard:

At BIRTV in Beijing, Aputure were showing a new budget-priced lapel microphone called the A Lav. The microphone features an omni-directional pickup pattern, and comes with a 20ft (6m) long cable, LED lights to indicate when the amplifier is turned on, internal and external windsocks, a mic clip and a carry case.

The A Lav powers on when the connector is attached and turns off when it’s removed. There is also a headphone jack for monitoring audio straight from the mic itself. Aputure expects the A Lav to be available towards the end of this year for around $30 US. That’s not a typo – thirty dollars – so it’s going to be interesting to see how it sounds. Could be a great backup option to have in your kit. It will be available with several different connectors for phones and cameras.

New pictures and details of the Veydra Mini Prime cine lenses in E-mount

By site editor Dan Chung:

A few weeks ago we reported on a new E-mount option for the Veydra Mini Primes cine lenses. Their 25, 35, 50 and 85mm T2.2 lenses can all fit on E-mount cameras like the Sony FS7, FS700 and a7R II and fully cover the sensor area if in S35 mode. The lenses are currently available in M4/3 mount and have proved very popular with owners of the Panasonic GH4. The good news is that the mount is interchangeable and all that owners of the existing lenses need to do is buy an additional mount ring kit. The kits will cost $99 and all you need to exchange the mount is a screwdriver.

A C-mount version of the mount will also be available also for $99. This should be a good option for users of the Digital Bolex.

The latest news from Veydra is that the mounts are on course to ship in October. Factory assembled Sony E-mount Mini Primes will be available in early 2016, so the only way to get E-mount right now is to buy the M4/3 lens and change the mount yourself.

We recently spoke to Veydra creator Ryan Avery and he told us: “We recognized the popularity of other mirrorless camera mounts such as the Sony E for APS-C and C Mounts for Super16. Since the longer focal length Veydra Mini Primes, 25mm, 35mm, 50mm and 85mm design naturally led to APS-C/Super35 coverage and our knowledge of the Super35 sensor on the JVC GY-LS300 in M4/3 mount, we decided it would be a simple user changeable mechanical mount change to offer Sony E and C Mounts. The user adjustable sliding focus scale design of the Mini Primes prevents the need for shims or other complicated back focus adjustments; just loosen three screws on the focus scale and adjust the infinity mark to your cameras flange depth after the mount is changed.”

In addition to the new mounts there is also a new lens collar that fits around the Mini Prime and gives an additional mounting point. When properly secured to a rig or cage this should prevent any slight play in camera side of the lens mount. This can be caused by variations in camera manufacturers’ tolerances. The lens ring will cost $119.

Fancy a S35 sensor camera with a great image, XLR audio, SDI and HDMI outputs, 4:4:4 colour, PL mount and built-in ND filters for under $4K? Read on…

By technical editor Matt Allard:

How do you get images like the ones above? If you have been looking for a camera that can output dual-link RGB 4:4:4, has 12.5-stops of dynamic range, a PL mount adapter, dual SxS Memory Card slots, built-in ND filters and professional audio for under $4K US, then you’re in luck. B&H are offering the PMW-F3L for $3995 US, which is a $10,000 US saving on the original price. The ironic thing is that is almost how much I paid for the RGB 4:4:4 S-log upgrade alone in 2011. This is tremendous bang for your buck and if you have no need for 4K or high frame rates, the F3 still produces fantastic images. The dual-link RGB 4:4:4 output, in my opinion, still gives you one of the more filmic-looking images out of any Sony camera. I still use the camera today for a lot of jobs and recently filmed with it in Afghanistan.

While the camera only records in the MPEG-2 long GOP codec in an 8-bit 4:2:0 colour space, with an external recorder there is no reason why you couldn’t use this camera for even the most demanding jobs.

Not long ago Sony also slashed the prices on the 6 lens Cine Alta PL set, which you can now buy for $12999 US. This mean you could buy both the F3 and 6 lens Cine Alta PL set for under $17K US. Add an EVF and a decent shoulder rig like the Zacuto Recoil VCT and it handles great on the shoulder. If you don’t need 4K then this kit is capable of some pretty amazing results.

BIRTV 2015: Movcam show two high end automatic focussing systems for cinema cameras

By Maxim Duncan and site editor Dan Chung:

Movcam were showing not one, but two automatic follow focus systems at the BIRTV show in Beijing. The first is the brand new MAF-1 auto follow focus which comprises a camera top sensor, control box and focus motor. The sensor provides real time distance-to-subject and then uses this information to move the focus motor on the lens. It appears that the system is only designed to work when a subject is in the central part of the frame, but if you use it in conjunction with Movcam’s three axis wireless follow focus system it can be engaged and disengaged at the touch of a button. This means the operator easily can go between autofocus and wireless remote manual focus depending on the shot.

The second system on show was the AcFocus Intelligent tracking and focus system which we had previously seen in prototype form. The system is now working well and Movcam were able to demonstrate it identifying and tracking multiple subjects in the frame. The unit can store up to five subjects in its memory which the user then selects which one should be in focus. You can see it working in the video below:
