I am considering MM 20 for carrying two bodies, E-M10 + P 35-100 and GM1 + P 12-35, the lenses attached to the bodies. I will bring also Samy 7.5 FE. I'm going to use it for city sightseeing, so the chargers will be left in the hotel. But probably I will take some filters. Do you think they will fit ? Or the MM 30 would be better?
