>>4402718>>4403008>backpacking>already have m43Don't get memed into larger formats by 4chan. You're considering a very slow to use, high IQ medium format camera. Consider your use cases:
>macroYou already have best in class. Even FF macro is stupid big and usually for less magnification. For macro you virtually always are stopping down to the diffraction limit so smaller formats are fine. Your MF gear would require cropping.
>landscape and "slow photography"You'd think MF would win handily here, but here's what you do instead:
- panos :get a very sharp standard or short tele, then take a bunch of shots and stitch in post. Stitching software is extremely powerful these days and can automatically stitch handheld panos no problem. With four shorts in a square and you're at FF, a few more and you're beyond GF.
- HDR or averaged HDR: high base ISO cameras can be compensated for in this way. You don't need to do the HDR look, that's a completely separate thing; a shot with a normal tone curve from an HDR stack will have superior tonality and DR
- pixel shifting: This is your laziest and worse performing move, but works in a pinch.
You may say this is a ton of work compared to just showing up with a larger format and shooting. The thing is, you'll be shooting REALLY slowly using a GFX camera as is. A m43 body like the OM-1 with a heavy ass pro lens will be lighter than your GFX body alone, and can be comfortably out all the time. You have options with m43.
>occasional wildlife or actionis actually possible with m43, unlike MF. The newest and best focusing GFX camera is still way worse than a PDAF m43 body, and telephoto options are nonexistent. You mentioned wanting a 100-400; this does not exist in GFX.
My recommendation is use your current gear and treat it like you'd treat a slower cam. Shoot panos or HDR stack or whatever. If you're still unhappy, rent before you buy. Ask yourself if the $5,000+ investment is actually worth it or if it's just GAS.
