The 27mm Push-On Lens Cap from Schneider is a simple, soft plastic slip-on style cap designed to protect the front or rear elements of a lens when not in use. The cap fits lenses that have a front or rear ring with an outside diameter of 27mm; this size differs from the threaded filter ring diameter of a lens.

Q: 1. Will this fit onto a Voigtlander 40mm Nokton lens?

A: Nice lens. I am not sure what lens cap size you need. However, the filter filter size is 43mm. For a screw on clip in lens cap, 43mm would be correct.However, this is a push on lens cap so 43mm may not This indicates that a 40mm Push On Lens cap is going to be too small, without question.Measuring for a Push-On Lens CapMeasuring the Diameter of Your Camera's LensAs push-on lens caps fit over the lens, one should measure the outer diameter of the lens to determine the right cap size. This should be done with a metric ruler, making sure the ruler passes through the lens' center point. The appropriate cap size is the diameter in millimeters.

Q: 2. 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: 3. Does anyone happen to know whether this Kaiser 85mm Push-On Lens Cap will work well as a lens cap for the Tiffen 82mm variable ND filter?

A: Kaiser makes a 82mm Tiffen 82mm variable ND filter version for use with 82mm filters.

Q: 4. Will this fit over a 24mm filter thread ring? Specifically a 24mm Heliopan UV filter on a Rollei 35 Tessar.

A: Yes, the Schneider 25mm Push-On Lens Cap can fit over a Heliopan 24mm UV filter mounted on a Rollei 35 Tessar.

Q: 5. Anyone test these on SLR Magic Microprime Cine's?

A: No, the Schneider 85mm Push-On Lens Cap has not been tested on the SLR Magic MicroPrime Cine lens. Also, as the SLR Magic MicroPrime Cine lens has a front diameter of 85mm, an 85mm push-on lens cap would not work with the lens. For a push-on lens cap to work, it would have to be slightly larger than the diameter of the lens on which it is to be used. The closest option in our inventory that may work would be the Schneider 86mm Push-On Lens Cap (B&H # SCLC85), though a lens cap that fits the filter threads such as the Sensei 82mm Center Pinch Snap-On Lens Cap, B&H # SELC82, may be a more accurately-fitting option.

Q: 6. what type of plastic is made of? Is it more like rubber or hard plastic?

A: It's plastic and hard but thin and therefore can flex just enough to grip the front of the lens.

Q: 7. What is the interior Dia. of this cap?

A: The interior diameter is 41mm.

Q: 8. 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: 9. 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.

Q: 10. 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.
