Summary: I have tried this on seven lenses, five Zuikos listed on the chart for the adaptor and two of my other manual favorites. All of them work very, very well. The only thing to watch for is the proper f/stop range. All of the lenses seem to lose sharpness if the apature is too large or small. A few minutes with a good test subject will let you get it worked out for each lens, though.
Summary: I purchased this adapter in hopes I can find used om lens at reasonable prices. My plan is working. I decided to get the Olympus brand instead of a knock-off. I think you will be as happy with this product as I am.
Summary: With this adapter, I'm able to use three OM lenses that were given to me by a co worker. The adapter fits quite snugly on my E500. The three lenses all work great, taking into account the limitations of the auto focus and metering. Worth the price if you have old OM lenses.
Pros: Durable, Easy To Use, Improves Product Function, Lightweight
