I know I'm talking 50ny in a Fuji thread..... But I picked up an A7Riii for it's extra features & kept my old A7 because I've had it years, I've done a lot with it, and it wasn't really worth a great deal..... Having two bodies is nice! Yes, there is a bit of extra weight & space, but generally I think it is worth it. I go A7Riii & 35GM plus the A7 & 85/1.8 or 70-180/2.8 - I'd rather carry the extra 500g or so of the A7 than have to keep swapping lenses. Plus, in my situation no zoom is going to cover 35mm at f/1.4 & 85mm at f/1.8
