The 38mm 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 38mm; this size differs from the threaded filter ring diameter of a lens.

Q: 1. Is this a replacement cap for a Pentax digital spotmeter?

A: The Kaiser 45mm push-on lens cap is a rubber lens cap with an internal diameter of 45mm that works on a variety of lenses and devices with the same diameter. We recommend using a measuring device (measuring tape or vernier calipers) to measure the front diameter of your Pentax digital spotmeter to find the correct fit.

Q: 2. 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: 3. 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: 4. 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: 5. 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: 6. 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: 7. 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: 8. 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

Q: 9. How well this Kaiser push on cap fits on a B+W CPL Slim MRC filter 77mm. Any other suggestions besides the original B+W (Schneider) push onThank you

A: I really like these lens covers, as an alternative to push-on caps:OP/TECH USA Hood Hat, SmallB&H # OPHHS35B Mfr # 8001112This will be the correct size for a 77mm.

Q: 10. Anyone willing to take a guess as to whether this would stay on a Canon fd 300mm f4, which originally came with an 84mm push-on metal cap? Thanks in advance.

A: Hi Tom, I have been using it on my 85 mm wide angle, it definitely stays on just a bit of a pain to get off with lens hood. Glen
