I'm a long way from an expert but have been taught that one needed to quadruple the resolution to see a "noticeable" visible change. I suspect it will be hard to tell the difference between 50 and 100MP without working at it. Pixel peepers will be overjoyed, the rest of us not so much, especially for $10k. I suspect there's a longer distance between $5k and $10k than between 50 and 100MP, at least in my wallet. I rented the GFX50 and loved it but ended up with a puny Sony A7RIII which at $3k when I bought it, checks almost all my personal boxes, lots of lenses from quite wide, to quite long, with lots of interesting variation between both in zooms and primes from multiple manufacturers. I really like Sony's eye focus as well as their pixel shift features. I'm a one system person now, having multiple systems in the film era just made me crazy. I had 35mm for action, medium format for when I wouldn't/couldn't carry the 4x5 and the 4x5 for "serious" work. I hope the GFX100 is a success because I genuinely like Fuji's business philosophy. Time will tell.
