Komodo lens mount is not functioning correctly, the body mount does not close tightly

[peter reisz]

Hi,
Komodo camera body lens mount is not functioning correctly, it does not work well.
I have tried to use it with several lens and adapters (Arri pl mount to Rf) but the lens moves in it.
the camera body mount does not close tightly.
what solution would be good?

Rotational play is not specific to the Komodo. This is a problem with every camera/adapter combination. That's why you see so many cages with lens mount supports.

you are completely wrong:
Issue Summary: KOMODO may have slight rotational play on the native RF mount on the camera body. This does not affect how the lens sits on the image plane.

I used this lens Canon RF 85mm F1.2L USM directly and it moved anyway
I Attached the Canon EF to EOS-R Adapter (that was included with the KOMODO package), and Komodo body mount does not close tightly.
this is a Red manufacturer's defect that makes it impossible to use in a professional way

You'll find some version of this difficulty in cameras from Sony and Canon as well, in my experience-- the basic spring-loaded mount design is very common, probably because lens rotation is less of a concern in the still lens world and that's where these designs originate.
One difference between the Sony FS7 and FS7 mkII is a lever locking mount, and it looks like there was a similar evolution between Komodo and Raptor.

"Hard mount" lens mounts are definitely an advantage of the DSMC2 cameras. You'll have to be your own judge of whether your professional work is possible despite the play. In my experience, I've been fine with a standard manual follow focus, or a Tilta Nucleus M or Nano, on a range of lenses. Lens motor torque and how smoothly the focusing ring turns are going to be significant factors in determining how well this works for you.

As Rick notes, you can improve the situation with lens adapter support, something offered by a variety of cages. There are also rod-mount supports that attach to lens adapters if you don't have a cage that offers this feature. (I have one such rod-mount adapter that grabbed the arca foot on a metabones adapter.)

Red had invented locking EF mount on Epic EF mounts 10 yers ago since then everyone is building this tension ring in to the photo mounts in order to reduce the play of the lens. Then for some odd reason Red didn't install this on Komodo. Then Reptor comes out and the tension ring is there in RF mount but they installed on newer Komodos?? This for me is mind bending puzzle. I have Komodo and i shoot Anamorphic so this type of play affects anamorphic lens alignment. its really sad that they didnt do this basic thing on Komodo

How am I "Completely wrong"?

The play is present on my Komodo, every komodo I rent and every RF mount camera I've used. It was also a massive issue for me with Sony E Mount adapters as well when mounting larger zooms.

I wasn't dismissing your concern just stating that it is not out of the ordinary and we all are dealing with it. Find a Cage/Adapter combination that will lock and support as mount to the body. I use Titla's cage with their PL adapter and adapter support foot.

I used it without any adapters, directly: Canon RF 70-200 mm f/2.8 L IS USM, Canon RF 24-70 mm f/2.8 L IS USM, Canon RF 28-70 mm f/2 L USM lens and "squeaks" in it. it would be expect a professional manufacturer to make a quality camera.
