About ProOptic

This cap features a front pinch style lens attachment, that does not protrude beyond the cap's diameter, rather than the snap-on outside grip style. The center pinch type is therefore much easier to attach and detach when a lens hood is mounted.

It stays on


from Oakland Ca  -  Hobbyist/Enthusiast

Just a lens cap? Still important to protect an expensive lens. This product goes on easily, stays on (more importantly) and comes off easily. What more could I want


Adorama Shipped the PROCLF77 Edge not


from Clearwater FL  -  Professional

Adorama shipped the PROCLF77 77mm Edge Pince lens cap. IT IS NOT WHAT I ORDERED. IT doesn't match the description as it is edge pinch and no lanyard. And FREE SHIPPING is a joke.

Lens Cap Review ... Seriously?


from Bloomington, IN  -  Semi-Professional

Can't believe I'm writing a review of a lens cap, but it's definitely necessary. Just wish I could write this as a generic review for all sizes of this cap so people would be more aware. This is by far the best lens cap I have ever had, quite a surprise considering it's the cheapest by far. I have mostly Nikon and Sigma lenses but I have also tried Tamron lens caps. None are as well designed as this one. Cap fits much better than others of the same size in my Sigma 10-20mm lens. Center pinches are very solid. Best of all, the included lanyard. It took me a second to figure out what I was supposed to do with it, but then I noticed the small hole in the lens cap. There's a small hole in the side of the cap and a slot in the side of the cap below that. You put the loop into the hole, pull it out the side slot, and run the rest through that loop. So simple and yet I have not seen this on any other lens cap from Sigma, Nikon, or Tamron. It does not in any way affect the fit of the cap in my lens, even with the lens hood. I hike a ton with my camera and the stock lens cap on this lens was the second big one I've lost while hiking. I tried the stick-on type lanyard to secure the cap on my big telephoto but just didn't like it. This is much nicer and just such a nice touch that it's included in a five dollar cap. Top quality, everything you could possibly need, and an awesome price...don't waste your money on the original equipment stuff unless you just want to advertise! Will definitely be buying more of these for my other lenses
