OM-D E-M10 Mark IV

Annoyingly I kind of straddle both sides of this (very helpful) comparison. I do want this as an everyday carry body, but I do have large hands, so I cannot understand whether the grip on the E-M10 IV is comfortable, or conversely whether the size of the E-M1 makes it a bit too big to take everywher

Yeah, very similar. The EM1s I think are too big. I also heard the instead of Em10 one can just go with EM5 bc the price isnt that different and you get weathersealing etc. I dont know about the Em10 IV specifically though. PL9 is nice bc its so small, the handling I guess is a personal matter, mayb
