The reshaping of the Cinema EOS line will continue into 2021, there is a Cinema EOS C90 in the pipeline [CR2]
- Thread starter Canon Rumors Guy
- Start date
While C50 might be the most interesting body for me, if it has good 4k with DPAF + some direkt left-right channel audio control (real knobs!) and some ND filter range (6 or better 8 stops) it might be a good alternative to the R6 for video - for photography I am well served by M50 and RP at the moment which deliver good enough video but are sometimes a little bit fiddly in terms of ergonomics.

"Canon is actively working on making RF mounts for some of the older Cinema EOS cameras" – I'm guessing that those might only be RF versions of mentioned older cameras, but NOT an RF mount option for existing C300 & C500 etc.
I'm saying this because Canon made a big deal about slimming down the ND mechanism for C70 for it to be able to work within shorter flange distance of RF. I believe this mechanism is "fatter" on EF cameras and can't fit inside the RF mount.

There's only so much money in the world. Get these released so I can give it all to canon.

If the name C90 is out there, can't imagine it won't be RF Mount. Sounds like an RF Mount with full-frame sensor (C500), since C70 has C300 III sensor.
The mount on C300 III and C500 II is interchangeable, so I wonder if you could put something like the EF>RF speedbooster on the C300 III - that would be huge.

Seems like the C500-2 Sensor would be the logical progression into the C90 .... or some updated version thereof. But a full frame sensor.

That is not possible – RF has shorter flange distance compared to EF, that's why you're able to adapt only EF lenses to RF mount and not the other way around. It might also be impossible to fit old ND system within the shorter RF flange distance, that's why I doubt any of the existing EOS C cameras will get that.

Technically correct, but what is being talked about here is not an actual adapter but rather switching out the lens mount itself. Which is a possibility on some cinema cameras.

The C90 ought to be the video version of the R5 -- full frame 8K sensor, RF mount, with all the pro-video features of the C70. We'll see...

I'll copy my initial comment partially here

C90 a version of R5? In which world some of you believe that c90 will lend specs from R5? R5 is an amazing tool but not even close in the league of c70/c300/c500!! C90 probably will get the same sensor of c500 mark ii or at the best an updated version of this one (maybe full frame DGO?). I remind you that c300 Mark III sensor has been measured close to 13 stops (Alexa on the top with 14) which is an excellent result! From the other hand R5 has only 10 steps of DR in all-i modes except raw which gives 11.6 if I remember good. So we r talking right now for an almost 3 stops difference in latitude between c70 and R5. So c90 will be better than c70 and will have much more difference against R5.

Technically, that isn't quite fully true.
You can use a metamaterial glass-or-acrylic lens system (i.e. etched light paths) that have tiny "drilled/etched" light tubes that bend/redirect the incoming light path spreading it wider or narrower to each pixel on the sensor even on a really short flange distance mount such as the RF mount or the longer flange distance of an EF mount. This means an RF mount CAN be mated to an EF mount!
It also means we could put a Sony G-Lens or even a PENTAX LENS on a Canon R5 or a 5D mk4 camera by making the proper metamaterial lens adapter!
Of course, the metamaterial glass is VERY EXPENSIVE to manufacture. Etched/3D-printed light tubes are HOW they make one type of negative refractive index metamaterial for optical stealth systems (i.e. search for HyperStealth and/or QuantumStealth) which REDIRECT LIGHT AWAY FROM or AROUND a destination object. This same technology can be used for highly direct multi-lens super-telephoto image sensing that fits in a small box!
i.e. usually used on Spy Satellites .....
