I'd like to see what the R5 does when it's not paired with a lens so old that it could legally order a drink in the US like they're using. The manual specifically states you don't get 12 FPS when using older glass, and from my experience with the EOS R, it also can prevent the high-speed viewfinder with incompatible glass.Well it looks like we have our answer:
There doesn't seem to be appreciable lag while not shooting. (Which does not mean latency = throughput. It just means latency is too small to be a human problem.) But when shooting both Tony and Chelsea struggled to keep the subject in frame. As I said earlier in this long winded debate, the bubbles introduced by full resolution capture/processing/storage is what most people notice and complain about. (Though general latency has been a problem as well on some EVFs.) I notice this stutter even on A9 bodies and while I think can anticipate/track reasonably well with those, it's still not as nice as an OVF.
The mark I 500mm f/4L IS they're using is from 1999. It's not even listed as compatible with the 12 FPS mode in the R5 manual, and I've seen no evidence of newer lenses or RF lenses having similar results to what they recorded, which is also on top of the fact the camera was already being forced to record the viewfinder feed on top of shooting images. Even if the EVF has a slight delay or slideshow effect, 12 FPS is going to look far better than what they were doing, and 20 FPS is going to look like a video feed on its own.
