Looking for some advice. I have the EM5 and the EPM1. I plan on bringing both bodies. I'm hoping to put a walk-around lens on the EM5 and perhaps an ultra-wide on the EPM1. I'm thinking of the following combos: 1) O 12-50mm + PL 25mm (or another lens) 2) O 14-150mm + P 14mm with wide angle converter Is there any point to bringing primes like the PL 25mm or 45mm? What about the 7.5mm fisheye? Thanks! Just want some advice.
