I put a Canon adapter on my 30 year old Olympus Zuiko 28mm yesterday; aiming to use it to photograph headstones for my family tree. What surprised me when I tested it was the almost three stops increase in speed it gives over my zoom at 28mm. At f8 I have to use 1/400 of a second compared with 1/60 for the zoom (alternatively I could use a narrower aperture). There is also a difference in colour; the Zuiko needs warming by 1500ºK. Results looks sharper than the zoom but sadly also have a touch of barrel distortion; not a good thing when most headstones have straight sides! I shall give it a try on my next outing to a churchyard.
