Kaiser's 80mm Push-on Lens Cap is for any camera or enlarger lens, binocular, tele-, micro-, or spotting scope lens. Measure the outside diameter of the lens barrel. Cap dimensions are the inside diameter of the cap, not the size of filter they fit. This measurement, in millimeters, is the size push-on lens cap you will need.

Push-on lens caps are not as effective as snap-on lens caps. They don't affix to the lens as securely as snap-ons, so they are easily lost. However, if your lens does not have filter threads this may be your only option. If the rim of your lens barrel is extended from the glass of your lens... you may be able to slide a push-on lens cap over the rim.

You Must Measure the Outside Diameter of the Lens or Filter You are Fitting
