    Metabones finally did it. Made a speed booster for the RF mount. Here is my first impression video test.

    That's interesting. It seems of limited life since I am guessing that only the EOS-R will have the 4K crop. I really only use ef-s lenses on the camera, but if it allowed the Sigma 18-35 f/1.8 be speedboosted for most of its range then I would probably pick one up.

    Don't forget about the upcoming Komodo from Red. It's not full frame but has an RF mount. If I was a betting man, I'd say the Komodo crowd is going to buy up a ton of these.

    Well, the new crazy rumors have two different RF mount full framers coming out sometime this summer - R5 and R6, kind of like Z6 and Z7 and S1 and S1R. One will be videocentric with 20 MPX, the other photocentric with 45.

    Or it all can be a hoax. But, given precedents, the rumors make a lot of sense.

    Aside of 8K Raw.

    I saw that 8K RAW rumor and dismissed it. But then I realized that Atomos has an 8K recorder coming out and an 8K external RAW output from the EOS R made the rumor make sense. I mean, it doesn't make any sense in my workflow or needs, but it does give Canon bragging rights and would convince some people that they care about video in their new mirrorless lineup.

    So much data though, even in CRL. 8K in HEVC seems to be more feasible. But, having a 45'sh MPX sensor does give them that option.

    Putting one of these on the M6 Mark II makes for a nice little full-frame-ish 4K camera from Canon (there's no crop in 4K besides the regular S35 1.5x one).

    Obviously it's not a video spec monster, but produces nice images and has 4K DPAF (a first from Canon for this price).

    Or 15 fps as on XT-100.

    Hybernatically speaking, HDMI 2.1 can send as much as 48 Gbps through but that would then likely be compressed into something like ProRes Raw, which is still 320-560 MB/s for 8K 24 fps and that's as much as 2 TB/hr. But, on the plus side, SSD prices keep tumbling down and down.

    CR removed the "Raw" part. But 8K remains.
