This thing screwed on perfectly to the Sony 35mm 1.8. No complaints. Also have this on my 50mm 1.8L Canon.

I was unsure if this would fit the Sony FE 50mm F1.8 lens… fits perfectly and appears to be the exact same lens cap model that lens comes with!

49mm is the go-to size for Sony NEX lenses, the kit zooms and the 16mm, 20mm, 35mm, 50mm all have 49mm threads. This is a well-made replacement.

Fits perfectly on my Sony full frame 50mm f1.8. So satisfying to replace a missing lens cap!

This UV filter has been a great addition to my Tamron 35mm for my sony. This filter is definitely more of a protector than a modifier at least in my use case, it helps to protect the exposed focusing mechanism of the lens and makes sure that no dust or particulates get into the lens. Overall I would say that this is a great filter to put on any lens as it adds a barrier between the front element and the world, and I didn't notice any negative effects on image quality by having this filter on the lens.

The way I use this filter is by combining it with a fast lens like the sigma 18-35mm f1.8 art. I use this filter in combination with the fast apertures to blur out the backgrounds in broad daylight without letting too much light into the picture. If I want to make it lighter or darker all I have to do is turn a ring at the edge of the filter.The only thing that gets me is when I turn it too much and it ends up unscrewing the whole filter out of the threading a little bit. But that's not a bad thing, its just a part of the experience.I bought it 8 months ago. This has been, thus far, an excellent purchase.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

This is a great tool assuming you have the Sony FE 14mm F1.8 GM Lens. If you *do* have this wide angle Sony lens, this will allow you to use both 1.1mm thick and 2mm thick filters in the 100mm Kase system. This is just the filter holder kit for the aforementioned lens--you'll also need a magnetic 90mm CPL filter. Excellent product for the specific lens/use case.
