Power ZOOM Lenses on the ATEM with a Pocket Cinema Camera

Photo Moment - June 10, 2021

If you have a powered zoom lens and a Blackmagic Pocket Cinema Camera (BMPCC), you can probably control it from the ATEM Software Control when connected to any ATEM — here's how!

Need an ATEM Mini?

What this tip is about…

In the previous ATEM (mini) Tip 11 I showed you how to control a Blackmagic Pocket Cinema Camera (BMPCC) through the ATEM Software, and in the case of the ATEM Mini Extreme or ATEM Mini Extreme ISO, even from the hardware. However there was one thing I left out — zoom control. That's because to control zoom on a lens, you have to have a powered zoom lens. After all, without a motorized zoom, how could the camera possibly zoom the lens for you! I recently had a Canon CN-E 18-80mm T4.4 COMPACT-SERVO Cinema Zoom Lens in the studio for a project, and quickly shot this video while I had it. I even figured out something interesting about zoom control and ATEM macros that I had never seen before. Check it out!

This video is by request! Lots of people wanted to see how the power zoom works, so here you go 😁 What else do you want to know? Also, please subscribe!!
What brand lens adapter were you using?
@In the Mix where in the video are you referring to? I did this a while ago but this was not an adapted lens; it’s a motorized Canon lens. Link in description.
@PhotoJoseph I thought the pocket cinema was M43, so I thought you might need an adapter to EF Canon lense.
@In the Mix that was the BMPCC 6K. It’s EF mount.
My guess is you could use a command 0 to make it stop, then use a streamdeck to have full control with a toggle button.
Does this lens work when adapted to a bmpcc4k?
Depends on the adapter. As long as there are electronic contacts (i.e. it’s not a dumb adapter) then it should work.
@PhotoJoseph fantastic, thanks a lot
Would this work on BM4K with a speed booster?
Hmm, I don’t know if the zoom electronics would pass through. That’s a question for the speed booster manufacturer. There are cheaper MFT power zoom lenses though, made by both Panasonic and Olympus.
Are there any budget options for remote zoom control of BMDPC4? Maybe some adapters with remote control? I'm trying to setup a small studio that I could operate on my own. I have ATEM mini pro, so the power zoom lenses would be great solution if they hadn't be so expensive.
Panasonic and Olympus both make a couple of power zoom lenses. Search “power zoom Panasonic lens” and the same for Olympus.
@PhotoJoseph Terrible lenses unfortunately as far as image quality. I've seen footage, highly not recommended. Definitely, there is room for a new power zoom for the BM M34 that will also work also with the BM Studio Pro 4K. Because of cropping it is difficult to get any lens like this aside for the B4 Fuji for the BM Broadcast G2 lenses. I believe the Canon CN-E 18-80 and 70-200 servo zooms have 1.9 crop factor making them not so useful for studio use without the Metabones .071 adaptor which is incompatible with the zoom demand from BM until that is developed (from Metabones support). 18mm for example with crop factor gives you 34mm on the wide end. Not good enough for studio work where you need wider preferably at least 24mm. Basically with all these problems and for integration with the AETM I am now looking at the Canon N500 PTZ cameras (for on location streaming events) and the Canon XF605 cameras for use in the studio, yet decent enough for shooting on location as well. Nothing else covers the basis, and we will have to give up on ATEM Zoom control on the XF-605. At least with a camera operator you can zoom in as directed from the switcher operator over talk back. Could be wrong about some things, can you see another workable solution?
Do you know of any power zoom MFT lenses that have constant aperture?
I don’t think there are any
@PhotoJoseph I just discovered this device. Pretty amazing. Never considered controlling zoom with the focus motor.
I can confirm that this works with both the Olympus 24-42 EZ and the Panasonic Vario 24-42 Power O.I.S EZ lenses on the BMPCC 4k. I can also confirm, that sending a macro with "0" stops the zoom and you can resume in either direction by re-starting the original macro.
Interesting! Thanks for sharing.
wouldnt adding a "zero" macro to the list give you a stop button? also would we be able to control any sort of follow focus type device to control power zoom?
I tried a zero but that don’t work. And no, the ATEM macros can only control ATEM hardware.
@PhotoJoseph that is what i thought, but i hadnt tried any power zooms, and i will be getting a couple follow focus controls for my 6kpro rig. so far it has been mostly worth working my way into the BM ecosystem.
Great video. Can I ask do you know of lens options for bmpcc 4K with the same ability? I’m struggling to find any if they do existing.
I can confirm that this works with both the Olympus 24-42 and the Panasonic Vario 24-42 Power O.I.S lenses on the BMPCC 4k.
@Emerald Audiovisual can you please let me know how. we have Panasonic Lumix G X Vario 35-100mm f/2.8 II O.I.S. Lens, the power zoom control don't work on atem software. Or let me know list of power lenses capable of zoom control from atem software, greatly appreciate your response
@abraham shibeshi I have only tested the 2 i've mentioned above. Those are pancake lenses. Can't see why yours shouldn't work, if those do.
@Emerald Audiovisual thank you for your fast response
@abraham shibeshi the 35-100mm lens is a power stabilizer not power zoom control. So unfortunately, it won't work as a power zoom for the atem. Sorry
What's a good servo lens for the bmpcc 4k?
Depends on your needs and budget
To stop you need execute “0” zero maco ;)
Is this lens (especially the zoom feature) working with the bmcp4k with a speedbooster?
Excellent tip!. Quick question: Let say I need to stream an event in multicam using the ATEM mini pro ISO, with 3 cameras, a laptop as a 4th input, and an SSD to record the program output as well as all four inputs,...and I would also like to have access to the ATEM software functions, would I need to have an additional laptop just to work the ATEM software? Thanks.
That’s advisable. Otherwise you will have to be very careful about switching to your laptop source, knowing with confidence that the right thing is on the second display. It’s not impossible to do with a single laptop, but it’s much easier with two. If you’re using it to play video or photos, consider using an iOS device instead. It’s much easier because the photo/video output is full screen with no UI.
@PhotoJoseph Excellent. great advise. Thanks!
I love your training segments . . . this one was very informative . . .
Thank you kindly!
one thing I have noticed using the ATEM with BMPCC, with the SEETEC ATEM 4 input monitor. It doesnt pass the camera controls through the HDMI ports. Shame.
That's interesting. They must no be passing the full HDMI protocol through their ports. Bummer.
Just an idea:
Stop zooming with hitting a additional macro with "0".

Can't verify myself as I do not have a BMCC.
You are spot on. This works.
Can you toggle the macro run button to suspend the zoom?
No, that would just start it again. But someone suggested sending a command of “0” which appears to be “no movement” and maybe that’d stop it.
Cool discovery, thank you!.
Has anybody a tip for a good mft Power-Zoom lens?
To stop the zoom where you want just create a macro with the zero value again! With the macros you've created it continues to press the button for infinite time. More exactly, Even when the lens reaches the max/min zoom it continues the effort like you are still pushing the button. So giving the value of zero again it stops! Even in the middle!? (I suppose!)
I was struck by the same thought. When you recorded the macro the first time you had released the zoom control and it had returned to the center position (no motion). You then discovered that changing that value caused the lens to move in a specific direction and speed which were dependent on the sign and value, 1.0 being the fastest movement. Since this number defines speed and direction a 0 would logically be don’t move (stop). Would be great is someone could confirm or disprove this.
Another assumption would be that for those who use Companion and StreamDeck to run macros, the not-zero values on Press Button, and zero value on Release Button would create a satisfying zoom function.
@Volleykanalen that it would. Ok I gotta test this!
@PhotoJoseph Would be awesome to hear if it did work or not :)
@PhotoJoseph please do... and let us know! Another great ATEM demo & tip!
This is fun. But for the price of this lens... I'd rather just see a 4k capable Atem Mini Extreme come out one day and then just crop in with the switcher or in post (being happy with an HD quality frame).
That's not the only lens of course… there are other motorized lenses. For me the biggest problem with them though is the cheap ones are usually variable aperture.
It's not only a question of cost.
Even VERY high priced zooms are not with constant aperture.

If you need constant aperture just set it fix to aperture provided on tele side.
@votoFoto unfortunately this is not possible on the BM4k as I quickly found out no matter what you set on the F stop if it’s a variable aperture you will keep that ratio.
I have used the bigger Black Majic mixer with the remote that allows you to do everything with these cameras. I find it funny seeing all these high end camera being used on ATEM which only handles HD.
haha totally. I use a 2 M/E in my daily production, and it's constantly back and forth between UHD for internal production and HD for streaming.
