I am currently using and olympus pen epl-1.. I just recently brought a 4/3 adapter to connect 40-150mm 4/3 lens to my camera. So i see that there are other micro 4/3 camera out there. So I was wondering if I can use a panasonic micro 4/3 lens on my epl-1. or will i need an adapter for it.. I would also like to know would I be able to buy any 4/3 lens and attach it on my camera using the 4/3 adapter i have already.
