A bit more.
Lens - actually have some positive things to say about the RF35, other than its size: image quality is surprisingly uniform all the way out to the edges. The good news is that despite its mediocre sharpness in the center at 1.8, it doesn’t deteriorate much further once you get to the corners. Stopped down to 2.8, it holds its own - and by f4 it’s competitive with the Ls. It’s sharp all the way out to the edges!
This has some personal significance as I was using it as a comparison to the M6/EF-M 22mm, in which I have noticed some visual IQ degradation near the edge. The RP/RF35 advantage in my eyes is a cleaner output (less noise) more so than a more detailed one (although if you stop down enough, you get that too). Of course, it has to be said that as compact as the RP/35 is, the M6/22 is in a different league altogether - almost pocket sized, so there’s that. But I’d argue it’s absolutely worth the extra bulk, especially in low light. The Full Frame advantage is apparent, which is great.
Camera - I may use this camera to dabble in video experiments from time to time so I tested this feature out. Video is the one area where I think MILC truly has the leg up over the DSLR. Being able to shoot video through the viewfinder is NICE. Even better is that my (older) computer can actually play the 4K footage from the RP (it couldn’t play the 5D4’s 4K footage)! I did note the crop and the slower focus, which is too bad, but I envision scenarios where I might actually be able to use that crop to my advantage...
Playing around with the silent mode, I ran into the dreaded banding issue. Seems to be most prevalent in incandescent WB/lighting conditions. Also, slight word of warning - note that with the RF35 the silent mode is NOT truly silent. The narrowing/widening of the aperture blades on that lens is CLEARLY audible in a quiet room (you’ll hear a brief “sh-sh” sound). And with the RP, there’s no way to force the lens wide open to avoid that (auto mode consistently stops the lens down in my indoor spot), so keep in mind.
