Is this the prettiest u4/3 camera?

Pretty? Maybe not. That Nikkor 135 F2.8 is just too big for that small body, Since you asked about pretty we are talking aesthetics so the design is unbalanced. I have the E Pl-2 and Nikkor adapters and find this to be the case on the practical level. Even regular four thirds lenses like the 45-90 look might unbalanced and are really hard to use. I love the ability to use other lenses but the beauty of micro four thirds is that high quality cab come in a smaller package.

BTW.that lend looks like new. My 135 F 2.8 Nikkor loos all beaten up.
