xcellent cps + nd variable, compact and easy to use. I would have preferred a through thread at the exit or the option of attaching a lens hood.

Bought for a Sigma Art Sony 24-70 and the Sony 28-135 (with Step Down), it is now permanently on my lenses. Additionally, having an ND and a polarizer on the same filter is a really nice surprise, especially at this diameter. For video recording and holding at 1/50 or 1/100 in broad daylight, this is best. A highly recommended essential.

It is a variable and polarizing ND filter. The ND is 5 steps, there are double, 10 steps (ND1000, 1024 to be exact). The polarizing filter eliminates light reflections on surfaces, cars, water, glass and also enhances the colors of the sky, leaves, asphalt, etc ... (search the internet for more information) Personally, I use it for videos so as not to by closing the shutter to lose depth of field (f9 up, now I can go to f2.3 without burning the frames due to too much light). I haven't removed it from my 35mm in a long time, I'm thrilled.

I tested it and it gives a good image quality, effectively not showing the x shadow. As a polarizer it gives what is expected. After getting used to the way of adjusting the mounting ring, polarizer ring and ND variation knobs it is alright. I mounted it on a canon 15-85mm, f3.5-5.6 USM with no problems.
The only disapointing issue is that i could measure the range of ND variation and it is not 4 stops (ND2 to ND32). I expected a 16 times light filtering variation but i got just 10 times. At same ambient and exposure conditions the shutter speed of my canon 90D changed 1 to 10 times slower. Just a little above 3 stops.
Despite, it is still a good quality and value for money having a double funtion.

Efficient circular polarization filter and very practical ND filter for long exposures in broad daylight, you can gradually switch from ND2 to ND32 (there are benchmarks to be found out). A very good manufacturing quality. Avoids having multiple filters to take with you. On the other hand, there is some vignetting that needs to be removed with LR, PS or others without any major difficulty. No external thread for attaching a threaded sun visor. Comes with a protective cover and a microfiber cleaning cloth.

During the window test when we set ND to its maximum value, I didn't notice X.

Excellent filter for the price. I think every lens should have a polarizing filter, so I bought this for my new lens. I can't tell you how beautiful the glass is...buy it and see what you think. I don't think you will be disappointed at this price!
