The C70 has been announced, the C50 hasn't. Isn't it a bit premature to state the C50 attributes with such certainty?
No, because everything that was leaked much before about the C70 was correct, apart from the naming and pricing, which they knew about not being final.
But they knew that they are going to be smaller derivatives of the C300 Mark III and C200
So they were just calling them Cinema EOS R300 and Cinema EOS R200
So there is a very high probability that this is what the C50 will offer.
Canon Cinema EOS R200 (Name not confirmed)
- Super 35mm 4K sensor (same as the Cinema EOS C200)
- No IBIS
- RF Mount
- Internal ND (10 Stops)
- CLog 2 & CLog 3
- 4:2:0 8bit internally onto SD cards up to 4K60 & 1080/120
- No RAW
- Dual LP-E6NH battery slot
- Price: $3,499 USD
The rest we can guess from how the C70 looks in detail, maybe they will equip it with a smaller screen, less inputs, etc. etc..
Looking at the C200, there is no indication of a 4K 10-bit 4:2:2 external output (only for 1080p)
So this is likely to be an 4K 8-bit only camera, which some people will not be happy about.
One can always dream about Canon changing their minds on that and the external is not limited, who knows.
It is the most entry-level Cinema camera they can do, and it still offfers a handful of things despite that, probably no need to buy new batteries or the quickest, most expensive SD cards either.
All in all, another interesting product.
