Found a FED-4 in a charity shop today. The lens has a M9 ltm fitting for which I have a M39 to E-M5 adapter. Focal length is 53 f2.8. Gave it a punt and although it is a wee bit lose it does at least work. Took a quick snap indoors to give it a try and will get out at some point to give it a decent amount of light to see how it hold up on the E-M5.
