BMPCC4K Lens Adapters

Greetings

Our church uses a BMPCC4K. We were donated a Canon Zoom Lens 75-300 EF III. However, the BMPCC4K is a MFT and the lens is EF. They don't match. I have already researched the Metabones Canon EF to MFT-T Lens Adapter 0.58x for Blackmagic Design Super 16 Cameras. The Metabones website states that it is not compatible with the BMPCC4K. It is also too expensive for our church to afford. Can someone please recommend an economical lens adapter that would adapt the Canon Zoom Lens 75-300 EF III lens to the BMPCC4K camera successfully?

Thank You

You should not look at any of the Super 16 Metabones adapters; those are for the earlier generation of Pocket and Micro Cinema Cameras, which had smaller sensors than the BMPCC 4K.

The Metabones adapters and speedboosters for Blackmagic Design MFT-mount cameras are all listed here; you want the ones that specifically say they are for the BMPCC 4K:

Your next decision is whether to just get a simple adapter (e.g., https://www.metabones.com/products/deta ... EF-m43-BT2) or a speedbooster (e.g., https://www.metabones.com/products/deta ... EF-M43-BT9). The speedbooster will reduce the crop factor and increase the effective aperture of the lens, but it's a lot more expensive. There are much cheaper simple adapters available if you want to go that route; probably Fotodiox has an affordable EF to MFT adapter but I'm not sure if aperture control and autofocus would be available.

If you don't get a speedbooster, just be aware that the "crop factor" of the camera's sensor will effectively make this a 150-600mm lens. In any case (speedbooster or not) you will need a very steady tripod to use this lens. If it were me I'd consider selling the lens and using the money to buy something more useful for video, unless you actually need a very long telephoto zoom for your church.

Also consider a Viltrox speedbooster. They provide similar if not same quality as the Metabones for a fraction of the cost. There are some comparision/test videos out there. The criticized aspect of the Viltrox over the Metabones is that there is a tiny bit of wiggle between the adapter and the camera's mount. But to be honest I never understood that critique, because the Viltox comes with a support bracket, which, if screwed on the camera's cage, eliminates any wiggling.

The things not working are lens stabilization and autofocus. BM team are working in a solution.
If you want Viltrox fully working only Firmware 2.3 for the adapter and 6.96 for BMPCC4k."

I'm pretty sure the Canon 75-300 EF III has no internal stabilization, at least not based on the specs I read on the Canon site. I guess the gyro functionality in the new firmware could help with that, but at any rate even on a good solid tripod I'd worry that a lens this long could result in shaky footage, including from floor vibrations from people walking around, depending on how the church floor is constructed and where the tripod is placed.

I can confirm new Camera 7.9 on BMPCC4k has better focus than the related in this post.
And gyro data works absolutely astonishing.

Viltro EF MII-2
Canon 40 mm 2.8
Canon 24-105 F4

Thanks Blackmagic Team.

The Viltrox efm2 has been excellent for me with Canon L lenses. Aperture and stabilisation work perfectly with recent camera and adapter updates. I also have access to a Metabones at work, it’s also great but see very little optical difference between them.

Okay Guys:

Thank You very much for all of your advice. The Viltrox EF MII-2 Adapter worked like a charm. I really appreciate your assistance.

Thank Again
