My company case for camera gear.

Worked well with my ND filter.

The filter is very well packaged and makes a high-quality impression. I've only been able to test it so far. It simply screws onto the lens and is easy to use.

This product works well. I expected better filtering, but that's okay. Looks very good quality. Super well packaged for transport. Received quickly.

It's a nice pair of sunglasses for my Olympus

It's a good product.

does the job

This is the first lens filter I have ever used. I've always read/heard that a good filter can make a significant difference, but until now I've never gotten one. This polarizing filter is very nice! The high-quality construction of glass and metal is easy to see. In my pictures you can see that the filter is attached to my camera, but I was able to attach my lens hood directly to the front of the filter. It has front pickup threads in addition to the rear threads. A really nice feature is that the front of this filter rotates freely. This way I can now easily rotate the tulip hood to the best position without the risk of the filter or hood loosening. I couldn't do that with the hood connected directly to the camera. But does the filter make a difference? I am happy to say that it works very well! I often take pictures through a window and it's very common for the picture to have some "haze" that wasn't there when I took the same picture outside. I took a picture through the window with this filter and was pleasantly surprised to see a picture that looked like I took it outside. I don't know exactly how this works, but it does. Just like polarized sunglasses, this filter "steers" the light in a way that enhances what you see. I am impressed!

Fast delivery, typical CPL packaging in the plastic box, nothing special until then. Very good anti-reflective coating without loss of sharpness with the CPL 55mm diameter D series. I've always lacked that little bit of sharpness, even that was remedied by, among other things, higher-contrast imaging. The picture uploaded here shows a 100% crop on the left without a filter and on the right with a filter. I was concerned here with the sharpness image, made with a Sony a7ii and a kit lens on 65mm with 1/100 f5.6 ISO 800. The second picture shows left without reflection and right with reflection. I didn't want to try if it was scratch resistant.
