Servo/CCU Control of Micro Studio 4k MFT 12-50mm lenses

PostTue Jul 23, 2019 11:19 pm

We're looking for a MFT lens in the general 12-50mm range that is compatible with the BlackMagic Micro Studio 4k and can be controlled with the ATEM CCU protocol.

Our use case is a wide angle shot most of the time but occasional need to zoom in out and adjust gain/Iris, white balance etc. via the ATEM. Does anyone have any experience/recommendation for lenses with this feature set and tested on the BlackMagic Micro Studio 4k?

There are only four native Micro 4/3 lenses that have servo zoom capability:

Here's the list:
  • Panasonic Lumix G X Vario PZ 14-42mm f/3.5-5.6 Power O.I.S. Lens
  • Panasonic Lumix G X Vario PZ 45-175mm f/4.0-5.6 Zoom OIS Lens
  • Olympus 12-50mm f/3.5-6.3 ED M.Zuiko EZ Micro 4/3 Lens
  • Olympus 14-42mm M.Zuiko f/3.5-5.6 Digital ED EZ Lens

Dave,

Bumping this thread given the Blackmagic Studio Camera 4K Pro and focus and zoom demands announcement. Have there been any additional lenses added to this list that support these new features?

I own a couple of the "Olympus 12-50mm f/3.5-6.3 ED M.Zuiko EZ Micro 4/3 Lens". They have been discontinued for some time.

I like what BMD has done with these cameras. The 10G Ethernet as a single cable connection for everything including power is a fantastic feature. I also love the new focus and zoom demands. I wonder if these will work with the Canon 18-80 C-NE lens via an active adaptor??

With BMD persisting with the MFT mount, I think for these studio cameras to really take off they need to commission a lens maker to make a lens like the Sony 28-135 f4 with full servo control.

MFT is a great mount BUT while BMD tout the mount as having hundreds of lenses to choose from, only 4-5 MFT lenses are suited to live production and natively support the zoom and focus demand. These lenses are all slow variable aperture zooms. We need something like a 14-140 f4 (or 2.8 would obviously be better) built like the Sony Servo lenses for these cameras to be taken seriously IMO

I completely agree and I feel that fujinon would do it

As to the 10GbE I like that idea. Thinking out loud what is the ethernet port of my ursa broadcast camera fiber converter and studio fiber converter ever going to do?

The Olympus 12-50mm f/3.5-6.3 ED M.Zuiko EZ is a great lens for the size and price, and I thin ok for many use, but I hope no one hopes to get smooth* zoom control from it. We tested it 3 years ago on this setup viewtopic.php?f=4&t=66387#p395321

The Zoom was not always that smooth, it has only few zoom speeds and it had some problems zooming and focusing at the same time, but I heard that was fixed later on so maybe that part is now ok.

I wonder why BMD is not supporting B4 lenses with this system, the Micro Studio had control output, but maybe that can be done via USB C.

Also it would be only logical to see soon zoom and focus servos supporting the system and par focal correction in camera (focus automatically corrected when zooming). It is not complicated thing to do but each lens will require their own correction tables and maybe calibration that would complicate things somewhat.

*it is perfectly fine to set the Zoom, but if done during sending live video, most probably does not look that smooth.

Just a note: most MTF lenses have very nice and smooth electrical focus control, but not all. Canon EF lenses often have ok focus control via Metabones speedBooster, but somewhat stepy and noisy. I hope there will be some kind of database what works and not.

Could it be a solution, if BMD developed a zoom motor similar to a Tilta Nucleus, that could be mounted on a rod in the now included base and connect to the zoom demand, to give better/finer control of zoom and would thus winden our options to include non-power zoom MFT lenses?

As far as I am aware, the list of native Micro 4/3 lenses with servo zoom capability is still just limited to those 4.

In general, the pace of new native Micro 4/3 lens announcements has slowed considerably in recent years, especially from Olympus and Panasonic which were the main supporters of the lens mount. Olympus sold its camera business in 2020 to Japan Industrial Partners (OM Digital Solutions) which says they plan to continue selling cameras and lenses, but obviously Olympus' decision to shed that business unit was an indication that their camera business was not doing so great.

And then Panasonic has shifted some of their attention in terms of camera and lens development away from Micro 4/3 and toward their full-frame L-mount lineup. Panasonic has developed a pair of video-oriented zoom lenses for Micro 4/3 in the past few years, with the 10-25mm f/1.7 and 25-50mm f/1.7, but neither had power zoom support and neither lens really seems to be directly geared toward live event coverage or ENG types of applications.

What is interesting is that Panasonic did develop a 13x servo zoom lens that covers the Micro 4/3 sensor area in their integrated lens DVX200 camcorder. That lens is a 12.8mm to 167mm (f/2.8 to f/4.5) which seems like it could be an ideal range for a lot of applications. But despite having that lens formula available, they never released anything similar as a standalone lens for interchangeable Micro 4/3 mount cameras.

Regarding the Canon CN-E servo zoom lenses like the 18-80mm, Metabones did release an update for their EF to Micro 4/3 Speed Boosters and Smart Adapters that allowed for servo zoom control through the camera. They claim this works for Panasonic cameras, and I assume the adapter is emulating what a native Micro 4/3 lens does for zoom control so I would think this might work with other camera brands as well:

There was some previous discussion about using the CN-E lenses with earlier Blackmagic Studio Cameras in this thread: viewtopic.php?f=2&t=74247
