Would certainly like to get my hands on one and give it a run through the paces. That said, my Nikon z7II with my f2.8 lens and my macros, in addition to my much longer length lenses more than meets my needs. I’m afraid that I’d lose too much focal speed and fps in that format for the photography I do.
I've got a gfx 50r and it's great fun, but I really wish I could spring for the 100S MKII. The updates, especially to the AF system are really good, but I'll have to wait a couple product cycles and grab one used. A few recent family snapshots:
1990’s Hassy 503cx I used for weddings for almost a decade with 50C-II back from 907x kit. No cables, no funky synch mechanisms- plug and play. There is a crop factor so ultra wides aren’t as wide anymore but so much mechanical fun with instant digital gratification of that’s your thing.
