i own a silver ep-1 with a black 14-42 kit zoom , a panny 45-200 ois m4\3, 2 cosina voigtlander manual focus lenses ,a 50 1.5 and a 28 1.9 and other stuff
im currently playing with some user adapted pentax auto 110 slr lenses manufactered in the 1980`s
a 24 2.8 a 50 2.8. they are tiny, tiny lenses indeed. but with a perfectly adequate image circle for the m4\3 sensor
these lenses were 10 dollars US each and the ep-1 body cap i used for an adapter was $5
15 dollars each
the 24 is the size of a plastic soda bottle cap, really!
its so tiny it almost looks absurd mounted on the ep-1,because of that, i recently finished a modifed "adapter" that i think is more aestheticly pleasing for the 24 2.8 pentax auto 110 on the ep-1
i will post a picture shortly

they are mounted in extra body caps from b&h drilled and affixed with a litle crazy glus at correct infinity focus . these fixed 2.8 lenses are a lot of fun, seriously limited by the fixed 2.8 apeture,
they are useful and very good none the less
check out 3 picture i posted in ep-1 user pics taken with these lenses to see how sharp and evenly exposed across the frame they are.
the 50 1s really remarkable,
i know you will enjoy your camera tremendously
welcome
