Just so we're clear, this sensor is performing WORSE than the R5 Mark II in electronic shutter and everyone was talking trash about for the past few months. So I'm prepared for more trash to be spoken. Is this performance in electronic shutter? Is it in mechanical shutter? In either case, not impressive.
It’s both funny and sad, the more I use my R1, the more impressed I am with my R3. That has primarily been because of ergonomic preferences, but I also haven’t personally seen any improvement in image quality at all. I was initially impressed with the R1’s high ISO performance until I took the same shots on the R3 and I conceded that the R3 was perhaps a little bit cleaner? I can’t properly test dynamic range scientifically, but it seemed just fine, but it is a bit of a shock to learn how good the R3 is - one full stop at ISO 100 better?! (I’m also exclusively shooting the R1 in electronic shutter and I would shoot the R3 in mixture of EFC and ES…the R3’s dynamic range and noise performance in ES is noticeably worse.) I would be curious to see the performance differences between the R1 and R3 in Electronic Shutter and Mechanical shutter, and if there is any improvement. I feel like the R3 may offer an advantage in mechanical shutter, but the R1 would perform better in electronic? Splitting hairs here...
There are a lot of quality of life improvements with the R1 that make me happy and would have me second guess ever moving back to the R3…but the R3 camera body design is PERFECT in my opinion and I haven't ruled out selling the R1 and going back to dual R3s. I actually really dislike the R1 body’s size and layout right now, it’s too wide (as wide as the 1DX) and I’m going to have to learn to love it or at least like it.
I kept one of my R3 bodies and don’t think I’ll be selling it. I’ve personally talked several R3 users out of purchasing the R1. Just by being honest...if you own an R3 and don't need full size HDMI, CLOG2, pre-capture, dual CFExpress, nearly flawless electronic shutter performance, and better AF - absolutely do not buy the R1. The market for this camera is very small and I scratch my head asking why Canon didn't or couldn't do more with the R1. Feel free to call me stupid and ignorant for acknowledging the minor improvements this camera made over the R3. They made the R3 too good? I'm not sure losing a full stop of dynamic range is a justifiable tradeoff for a stop faster readout. A full stop of dynamic range performance will absolutely be noticeable in some situations.
Just my $.02.
