A question to the Olympus OM lenses experts: Is there a noticable performance difference between the older non multi coated OM lenses and the newer MC lenses?
Similaly between the older Zuikos with a letter in front (e.g. F-Zuiko) and the newer ones without that letter?
not a huge difference between SC and MC versions. Generally the MC are a little less ghost-prone if shooting into direct light sources but it's a relatively minor difference.
