I'm debating between picking up a used Z50, Olympus D-E-M1X, or some other MFT/APSC as a backup behind my current & future main body. I have a decent bit of F mount glass and have been stacking on Z mount glass slowly. Specifically looking at APSC and MFT, I kinda want to toy around with MFT to be honest. Fuji X-H2S would prolly be the best choice overall but I don't feel like throwing that much.
>Sub 1k USD used preferably.
>Viewfinder is a must and Snoy APSCs are non-option.

Z50 Pros:
>Native Z mount with a future of lenses to go with it.
>Already have FTZ II and multiple contactless adapters for F mounts.
>Better sensor
>Can be had for 525-550$
>Already know the ecosystem

Z50 Cons:
>No IBIS
>Ext. grip means extra cost
>Reach won't be that much more without using a substantially longer lens compared to DX cropping on 45MP


E-M1X Pros:
>Insane levels of weather sealing
>Full body grip comf-ness
>Dank IBIS
>Larg MFT line of lenses

E-M1X Cons:
>MFT Depth of Field
>ISO performance is shid?
>Will need MFT lenses for Wide Focal lengths
>750-900$
>Almost blatantly confusing menu system
>"Dead" mount

Looking into the XT-3 as well. Grip looks like shit though for larg hand bois.

Opinions?
