This filter is well made and features a metal ring that is easy to hold and rotate. At first glance it is not a slim or flat ring, being thicker than my other slim filters. The concern relates to possible vignetting when using a wide angle lens. The product description claimed that it can be up to 14mm wide without vignetting. While I don't have an extra-wide lens that wide, I tested it on a 12mm fourth-third lens, which is equivalent to a 24mm full-frame wide-angle lens, and I saw no signs of vignetting and the ring is lighter hold and rotate than some ultra-thin filters. Overall, this filter offers good value for money and is cost effective to protect your lens.

Despite the mention in the description, saying that is not good for wide angle lenses, I purchased it for a Viltrox 16mm f:1,8, EF mount. The results are outstanding across the entire range of the filter. No X cross, no vigneting. At least for this specific lens, the filter is perfect. Is true, the size of the barell is twice the size of the front lens, leaving enough room for any kind of filter.

I needed an ultra-thin UV filter for my wide angle lens and this filter works great! I was still able to screw in the lens hood and not get any vignette in the corners. This filter also seems to alleviate some of the glare I experienced. The surface of the filter is super clear and doesn't interfere with my camera's autofocus. We recommend.

Made from high quality materials. Precision built. It offered the least amount of resistance I've had when screwing on a new filter. It's very thin so it doesn't interfere with wide-angle lenses (as much as possible).

Using a full-frame DSLR, I made side-by-side pixel-level comparisons between shots with and without a filter. One photo was a wide angle shot of the included sky on a high UV day.

Results: Well, I didn't see any difference in color or richness in the high-UV shot, so I wouldn't buy it just for that. Most of the time, people just buy these as lens protectors (and believe me, they've saved my bacon a number of times on high-end lenses now!). As a lens protector, you want it to be as unobtrusive as possible, and I'm happy to report that I can't tell a significant difference in any test shot - color balance, sharpness, contrast - they're all so close I've never been could definitely say that every tiny difference was due to the filter.

The filter works best if you have a lens that is greater than 35mm. When the lens is too wide angle is when you get the X looking area

Hi use the filter on my wide angle lens. Unfortunately, at the max setting, a lens flare forms, which unfortunately doesn't look so great. At min setting it is ok (no lens flare) Processing is super. Unfortunately only conditionally usable. ML

I bought this ND filter for my wide angle lens and am very satisfied with one thing. The filter is well processed and makes a high-quality impression. But when the filter is on the lens, unfortunately the lens hood no longer fits on it because the front ring is slightly larger than the lens diameter. So far I could not see any color cast in the pictures I have taken so far.

I needed a UV filter that would match the wide angle zoom lens I bought and make it an ideal complement.
