Q: 1. Will this push-on cap fit my Minolta MD Rokkor-x 50 mm 1.7?

A: A 50mm lens does not typically refer to the filter threads and or lens diameter. This lens happens to take a 49mm filter but that is the inner diameter of the lens. Your lens is probably anywhere from 51-54mm. Most people buy 2 or 3 different sizes and return the ones that don't fit.

Q: 2. Does it fit on Heliopan 62mm Variable ND filter?

A: If your ND filter have the female thread to receive it, it will work. This one have no female thread, only the male one, so it must be the the last one to be mounted.

Q: 3. Will it fit OK with a step up ring? I'm planning to use these with some lenses that have step-up rings to 82mm.

A: No, suggest just using a threaded screw on cap if really needed.

Q: 4. 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: 5. what is the inside diameter of the cap?

A: This is a 65mm push on cap. It is designed to go on a lens with an outer diameter of 65mm, meaning the inner diameter of the cap will also be 65mm.

A: Unfortunately, we cannot guarantee the Kaiser 41mm Push-On Lens Cap would work on your listed equipment. The Kaiser 41mm Push-On Lens Cap is designed for lenses that have an outer diameter of 41mm, or 1.614 inches, so 1.625 inch or 1.630 inches may be too large. However, I would recommend that you can purchase the push-on lens cap and try it on your equipment. If it does not work for your usage needs, you have 30 days from the purchase date to return the item for an exchange or a refund.
