Hi, I've the opportunity to pick up the Olympus Zuiko 28mm f2.8 and Olympus Zuiko 50mm f1.4 for £75. Sadly I don't know much about anything outside of Canon so am a little lost. I know I'll need a converter to change OM to M43 but thats no biggie. I also found out there are different models of what looks like exactly the same lens by name (well at least the 50mm 1.4), so heres a link to the picture. Link Any feedback would be great. Thanks.
