The Sony pinch caps seem to hold better than other brands lens pinch caps .I don’t know about canon or Fujifilm but use Nikon and Sigma . Live the new Sigma Magnetic Caps the best . Nikons pinch caps are just ok and the Sigma pinch caps are hard to get on and the square edge on the outside of them let them get knocked off easy . I’ve lost quite a few Sigma Art lens caps by popping off from knocks . The Sony caps hold tight and are shaped not to have an edge to catch .

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.

There’s something simply divine about the 35mm focal length — and this lens remains the only native option for the RF mount. I’m coming from an EF Sigma 35mm F1.4 to this lens. I do miss the slightly wider aperture of the Sigma — and the additional blur it creates. But at the end of the day, this lens is pretty much just as sharp and so much smaller than the Sigma, especially once you factor in the adapter. Not-quite-macro close focusing is another major perk, and is quite useful for small animal photography. Overall, a tremendous bang for buck.

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've used this with my 35mm f/1.4 E-Mount . By far, this polarizer has not came off my lens when i took it out for travelling to Hawaii. It gave my shots more contrast, darkens the highlights to the point where I can use the image and of course, see through reflections. As a polarizer, it does what most polarizers do, I definitely would recommend this filter!Highlights:- Tiffen helps with maintaining the sharpness- Blocks reflections- Ups the contrasts in your shots and reduces highlights

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

I bought this to go along with my 24mm stm pancake, 18-135mm kit lens and my sigma 18-35mm art lens. For $125 you really can't go wrong. The stm focus is loud especially compared to the kit lens which is basically silent. I paired it up with a JJC LH-68 hood and the whole package is light and small. Not sure if I need the 24mm pancake now.
