Olympus Lens: Primes - Olympus 45mm f/1.8 ED M.Zuiko Digital (Tested) - SLRgear.com! I must have had a bad copy (I returned it to Oly). Not only would it not catch focus, it was pretty darn soft at 1.8. Softer than these charts would indicate. I might have to try another copy of that lens at some point.
