Q: 5. Will this fit on a Nikon 50mm lens?

A: No, 50mm is the focal length and not the outer dimension of the front of the lens. You will need to measure the outer diameter of the front of your lens to determine a push on cap size.

Q: 6. Will this work on an Olympus C-210 teleconverter?

A: As the Olympus C-210 teleconverter has been discontinued and is no longer available, and I see no specifications listed for the unit online, I would simply have to recommend to measure the outer diameter of the teleconverter in millimeters (or convert your available measurement into millimeters). If the outer diameter measures between 56-58mm, then it should fit. If not, you would have to find the size that is equal or slightly larger than your outer diameter measurement.

Q: 7. What is the material?

Q: 10. does the 81.5 mm fit an 82mm step up? why 81.5mm?

A: I'd measure the outside diameter of the the step up with something accurate like vernier calipers or a micrometer. I purchased the 90mm push on Cap to fit a Schneider centre ND filter which I measured to be exactly 90mm outside diameter and the cap was a fairly tight fit.
