 p.1 #3 · p.1 #3 · R5ii Video Review's - Undone, Wild Alaska, Hybrid Shooter, Jan Wegener Links | |
Duade - another bird focussed photographer I have a lot of respect for, has done a review and confirmed what I have been seeing. see about 16min into the video.
The R5ii has more noise at high iso (12,800, 15,000 ) than R5 - to the extent that he says he will likely stop using 12,800 as an option for bird photography (about 16mins into the video). He also concludes that he still thinks that R5ii is a better camera for things like clog2, no rolling shutter/video/precapture/30fps[better dynamic range at electronic iso 100-400 because of 14 bit] but that he is disappointed to take a step back. [I don't think he mentions what he uses for processing DPP, LR, ...]
[Surprisingly, he also concludes that the 5dsr has better dynamic range at high iso than r5II, as well. I did not notice this because the ai noise software was introduced after the 5dsr, but it is believable but irrelevant because 5dsr was not overly useful because of a/f or fps etc.]
My testing [ https://www.fredmiranda.com/forum/topic/1870671/ ]concluded the same, R5 is better for noise, but at 25k you could bring the picture back to reasonable with adobe auto noise (ai) correction. I was hoping that this was an adobe profile issue, but it appears that it is a real issue that will forever haunt my low light bear pictures, with R5ii. They will be close but R5 images would have been better. This is consistent with my prior testing. I was (am) hoping that it was an adobe profile issue, that would be fixed, but likely not. So I guess, that if you are a very low light shooter, and don't value 30fps (over 20) or precapture - you should stick with r5. [this is even more disappointing to me because I don't value 30fps, r5 was good for me on video, and precapture is nice but infrequently useful, the biggest gains I will get is better ISO performance at <800 iso (14bit) and variable fps - because I shoot bears (at low light) and landscape (on tripod) - not birds]
I won't stop using 25k, because my bears come out late or early, but I will have to use more ai noise management. And I am debating keeping my r5 or selling my r5ii. Marginal gains for birds for me, but significant high iso losses. Better variable fps, and precapture and clog 2, but worse noise at high iso.
[he also concludes that precapture does not work well when the bird approaches or leaves the camera and the a/f is jittery on sticking to birds at times - but this is not a new report. This is likely to be improved with updates]
