Pick your two favorite lenses

25 and 75. If the 45 was the panny macro then I'd take it over the 75 for versatility reasons but between the Oly 45 and Oly 75 I'd take the 75.

I have both 45's and unless I need 1.8 I almost always put on the Panny. No one seems to be able to tell the difference in tests I've done with the two and the Panny can do Macro.
