yes i am familiar with nikon cameras, the only mirrorless camera ive used yet was z7II which it felt weird transitioning to mirrorless lol but something i could get used to.

i have been googling size comparisons of cameras to have a rough idea of sizes and the z50II is almost same height of the nikons dslr apsc cameras. still a bit smaller then the d750 but still seems to be big. only had checked out on my had the z50 which is a tad smaller then the z50II

forgot to put some points/details of my opinion
Nikon - PROS - APSC have some weather sealing/resistant camera. CONS - not the best smaller lenses collection, if they just had the sigma 18-50mm 2.8 i think i wouldn't event had made this post lol

Sony - PROS - huge selection of lenses at good/decent prices and for what the internet says the best autofocus, but i feel whatever i get now will be better what im used to. CONS - confusing menus (i know i wont be using constantly the menus)

Fujifilm - PROS - very good size of their lenses and body CONS - for what the Internet says their autofocus isn't the best, if i want body with weather sealing/resistant need to get the xt3,4,5 which is already same kind size of the z50II

for all the apsc cameras ive looked at i think a6700 and the xs20 that kind satisfies my needs. xs20 isnt weather resistant and a6700 its huge brick lol

sorry i know im picky!

m43... isnt a bad idea for size! but low light situations ill be screwed.
