Q: 1. does it fit a Pentax da 40mm lens?

A: As long as the lens is 40mm in diameter, this lens cap will fit.

Q: 2. I see that you listed an outside diameter of 110mm. What is the inside diameter?

A: The diameter listed is for the outside diameter of the lens barrel it fits so it's referencing the inside of the cap less a small amount for a friction fit.

Q: 3. Would this fit on a Lensbaby Scout or composer? (I want to store my Scout and Composer without the optic so I can swap quickly. The Lensbaby lens cap fits the optic.)

A: The Kaiser 64mm Push-On Lens Cap will not fit the Lensbaby Scout or Composer. You will need to use the original lens caps from Lensbaby on these lenses. If you need protection for these lenses, you can check out the Lensbaby custom lens case for the Composer http://bhpho.to/1gpQo6H or the Lensbaby System Bag: http://bhpho.to/1hctcKV

Q: 5. Is the inside diameter of the cap 48mm?Thanks,Dave

A: Yes, the inside diameter of the Kaiser 48mm Push-On Lens Cap is 48mm. However, do note that it is often recommended to purchase push-on lens caps 1-2mm larger than the diameter of the item upon which it is to be placed. Getting a size exactly the same size as your item would not fit.

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. 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: 8. Will this fit a Konica c35 automatic?

A: The Kaiser 38mm Push-On Lens Cap is too small for the Konica C35 Automatic--it has a 46mm filter thread, so most 46mm lens caps will work with it.

Q: 9. Can this lens cap fit the Canon AF35M film camera?

A: Being that the camera takes 48mm filters, i would venture to guess that a 50mm push on cap would work. https://bhpho.to/2MZ1WrF
