This does sound exciting:
- Lens breathing correction
- Pre-shooting buffer
- Removal of 30 minutes record limit
- Vehicle tracking AF mode (bikes, trains & planes)
- Additional tracking for more animals
Another two that would really be useful are
- Subject Only AF for video
- UVC/UAC support
If the AF modes were changed to match the R3/R7/R10/R6II style, it would be awesome. Bringing the R5 feature set close to that of lower-cost models to extend the life of the camera makes sense.
I also don't think it is crazy for Canon to introduce a slew of new features 3 years into the R5's life. They could introduce a number of "teaser" features that have big caveats that would be removed with the R5 II, just to get everyone primed to upgrade.
For example:
- AF "3D" limit, i.e., both a box in the frame and depth focus limiters
R5: Only with ES and restricted to 3fps with a worse rolling shutter than the current ES
R5 II: Full 40fps ES (and other slower modes) with minimal rolling shutter, i.e., better than that of the current ES, as well as mechanical shutter support
- High-resolution pixel shift
- R5: In-camera 8-bit jpeg only with quality that is only minimally (if at all) better than AI SW upscaling.
- R5 II: Raw file with clear improvement over AI SW upscaling.
