I think a GX7/GX80 etc would be fairly much what you’re after. I have a GX9 and it does everything you’ve asked for, though is possibly slightly more than you want to pay - I paid £440 I think. The GX8 was a departure from the formula that made these cameras so special, but the 7/80/85 are all the same body layout. The 85 is pretty close to the GX9, but with a fixed EVF as opposed to tilting, 16mp as opposed to 20, and a few less bells and whistles. I chose to save a little more to get the GX9 and don’t regret that at all, it’s a fantastic camera, but if you could try out an 85, you may find the it’s what you’re after. Hope that helps
Wow, that’s a lot! USD? I kind of expected it to be a similar figure to what I paid, but if that’s in USD, that’s about what I paid for my used Fuji X-T5! I bought mine a few years ago, but I’d have thought they’d have gone down in price, not up! The world is weird these days, huh?
I’ve never used any of the older cameras than the GX9, but from what I’ve read, they’re pretty similar to operate. The focus peaking on mine is pretty good, I use manual lenses a lot, and it’s a pretty enjoyable experience
