Q: 1. what is the inside diameter?

A: It will be a few thousandth of an inch under 85 mm. That provides slip on at low effort with grip strength from the resilience of the plastic material snug on the outside of the lens barrel. Dimension based on outer diameter of barrel not filter thread size.

Q: 2. Hi, Is this made of rigid plastic material or rubberized malleable style?

A: Kaiser 80mm Push-On Lens Cap is not rigid, you can vend the cap if you put enugh force. However it would not fit into larger diameters.

Q: 3. Can you please verify if this cap will fit on a 80mm hasselblad lenses?

A: If the focal length is 80mm, it doesn't mean the cap/filter size is 80mm. It depends on which version of 80mm lens it is. Typically a push on lens cap should be about 2-3mm larger than that of the filter size. For example is the lens has a 77mm filter thread, a 80mm push on cap should work. The older Hassy lenses took Bay 60 filters, that would be about 60mm in diameter , so a 63mm push on cap would probably work.

Q: 4. 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: 5. Does this fit the Leica APO-Summicron-M 35mm f/2?

Q: 10. Will this fit a mamiya medium format 90mm lens?

A: That depends on the exact lens you are using. This is not for lenses with a 90mm Focal Length, but for a lens that have an outside diameter of 90mm. With a vintage lens you will want to use a tape measure to see what the outside diameter is. From there this listing has a drop down menu that shows different sizes, there may be a size that better fits the lens you have.
