Excerpt: I mean, how complex can a thing be? The Sony lens cap works like it should, works with the original prime lens I have, as well as my Hoya filters. The indents in the front, so that you can operate it with easier ergonomics are nice. Definitely a good buy.
Excerpt: I bought this because I had a filter added on my RX100 to enhance my monochrome photography. The filter is from Sony (VF49MPAM) as well. The lens cap falls in a bit tight and gets caught in the threads, probably because of the type of spring system in this cap. It is a nonindependent plastic spring.
Excerpt: After 20 months of taking it off and putting it on my Zeiss Sonnar E 1.8/24 Za lens the lens cap's spring lost its zing. It fell off somewhere, quietly, apparently. This is a perfect replacement. Snappy.
