B+W #310 49mm Snap-On Lens Cap

You Pay: $6.88
Product Highlights
  • Made in Germany

The B+W Snap-On Lens Cap #310 model has two spring-mounted claws at opposite sides which attach to the inside of the filter or lens threads.  They work on any lens or front-threaded filter with the filter size that matches the size you see here (49mm in this case).  If you have a filter on your lens which has no front threads, you would instead need a B+W #305 model cap.

      Comments about B+W #310 49mm Snap-On Lens Cap:

      The important selling point of this cap, for me, was how securely it supposedly stayed put, and also how thin it was, as I intended to use it in the field, in the cold, meaning my camera rides under my jacket with cap in place until it's time to shoot. It's fairly secure, but pressure on just one of the releases can release the cap, so it's not actually usable in the field for lens protection in lieu of a protective filter. If you don't keep the cap attached once you start shooting, this won't be a problem. It's very well made and better looking than any other cap I've seen, but don't expect too much in terms of performance ahead of other caps of this type.

          I use the cap whenever not using the lens hood and when storing the camera.
          This cap is thin, works well and is nice looking for a lens cap. The cap has a textured look which blends with my Fuji X100.

              A solid and attractive lens cap with a nice looking texture. It fits under the lens hood of my Pentax DA 15mm lens. There is absolutely no rattling or play. I have purchased two from B&H. A recent copy came in a cardboard package which was a bit of a disappointment because the one from two years ago came in the standard B+W plastic filter case.

                  This is a great little lens cap. Very nice and secure side mounted locking tabs which for me are much preferred over non-side locking tabs. This cap stays snug and secure when affixed to a B+W UV lens filter. And the cost was very affordable.

                    Lens protection on an expensive lens. Nice and simple design and quite well made.

                    Does the job.

                      I bought these for my Pentax prime lenses. The slim size adds minimum size when packing my lenses in a lens case or bag, and the pro look is perfect on the classy Pentax prime lenses. Clip on action is strong but easy to release. Highly recommended.

                          Comments about B+W #310 49mm Snap-On Lens Cap:

                          I was looking for a snap-on lens cap for my Pentax DA Limited lenses which have gorgeously build metal lens cap, but not practical due to their screw-in design. There're many third-party 49mm lens cap choices available that I've tried, but I finally settle on B+W for all my Pentax Limited lenses (all of them share the same 49mm thread). This made-in-Japan B+W cap is really well-made, solid and has an expensive look/finish. The lens cap comes with exactly the same packaging as any B+W filter, which is excellent. It has no letters/brand name on the front (a great feature!), instead it has a really nice textured design which complements the rubber skin of most DSLR very nicely. The design of the front lens thread and lens hood of my Pentax DA 15mm & 35mm Limited lenses allows this B+W snap-on cap to work as it should with collapsed lens hood. So, the way I use it is: take off the cap, then extend the built-in hood. But if your lenses have fixed lens hood design, you should first consider how you'd like to use your lens cap. Because this B+W cap doesn't have 'center-pinch'-type of finger grip. If you don't use lens hood at all, of course there's no issue whatsoever. Highly recommended to consider.
