Q: 4. 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.

Q: 5. 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: 7. 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.
