I've come to the conclusion the smaller camera bodies in the system suit me best. However, I'm wondering if the small size isn't going to be a hindrance with larger lenses (of which I haven't purchased any). The largest lens I own is the Panasonic 25mm, which IMO still balances OK on a small body like the EPL5 or GF3. But how much larger of a lens can I use before the ergonomics just become ridiculous? Are the 12-40mm/35-100mm factible for casual use on a small body? How about the 75mm or a Voigtlander? I would appreciate anyone sharing their experience in the matter!
