Did some architectural photography for a library that my firm did the engineering on (though I didn't work on this project). All R5 with Sigma 14-24mm f/2.8:
The first time I shot a handball game (audiences weren't admitted until the championship game), and probably the last time (my son (#13) is leaving this school). But hey it was fun - this camera makes it too easy.
Picked up the 7Artisans 28mm f/1.4 - I first shot it on my R6, and it had really bad magenta color shift at the edges and corners, which was a pain to correct, and I figured it just wasn't going to be a good lens for RF mount. Was very pleasantly surprised when I put it on my R5, and found absolutely zero color shift in the corners. It's got a lovely rendering...almost Zeiss like stopped down. Certainly not a perfect lens, but I think I'm going to like it.
