For those interested in the photography side of things, been putting the Canon R5 through its paces before the 30 day keep it or return period expires - or at least as much as I can do stuck at home. Latest set of tests aimed at pushing the camera to a position where the images could reasonably be a bit iffy - ISO1600, 1.4x on the 600mm f4 ii, f5.6 so shot wide open with minimal depth of field where and focussing errors will become apparent. The Siskin is obviously a significant crop, at c24% of the full image, but still plenty of pixels in there. Bear in mind as well you're seeing here tiny jpegs with long side of 1024 pixels created from the original cRAW files - for ISO1600, which generally is as far as I need to go, I think these are pretty acceptable.
However next series of tests will be pushing the ISO to 3200 and beyond and seeing far this can be taken before IQ becomes unusable
Excellent Mark.
