55mm MCUV Protection Filter with 28 Multi-Layer Coatings HD/Hydrophobic/Scratch Resistant/Ultra-Slim UV Filter for 55mm Camera Lens Nano-X Series

Just received today. It feels light, even a bit flimsy when I hold it in my hand. Nevertheless, it feels quite high quality. It seems to have a thinner glass substrate compared to the B+W filters I have. Given the 95mm size, I even have a feeling that the glass might warp under stress, although I know that's unlikely. I'm curious about the optical performance. In terms of price, this is unbeatable, what all other UV filters should cost. There's just no justification for seeing a UV at $200 or even $300. Selling a UV for $200-300 sounds to me like people want the money but don't want to work reasonably hard.

Very good

needed to protect the lens on my FZ300 and this filter has some good reviews. The overall quality seems very good and the packaging works well when it's larger than necessary. The filter threads well without affecting hood fit, stows or deploys upside down and shows no vignetting at 25mm. There doesn't seem to be any noticeable degradation in photo quality. The glass seems to attract dust and had to be cleaned several times before I could attach it to the camera with no particles on the inside. The outside needs frequent brushing. I'll update if I find more issues in the future, but this filter seems like a good buy.

Exactly as described

fine

bought this for a rarely used camera. It's still a valuable collector's item that I want to keep in excellent condition and that means I had to protect the lens. I only have filters with the Zeiss "T" coating made of German Schott glass on the cameras that I use a lot because I think they are the best multi-coated filters I can afford, but I can't spend the money on them spend on a camera I rarely use. Any camera that is threaded to accept a filter deserves the protection that comes with a filter mounted in front of the actual camera lens. I would rather risk damaging the AR coating of a filter that can be easily replaced than risk damaging the actual lens on one of my cameras through cleaning and exposure to dust or chemicals in the air. This brand of filter came carefully packaged and the filter holder that comes with the filter is well designed and provides excellent protection for the filter when it is not on the camera lens as I am using a different type of filter. This filter has multiple AR coatings on both sides of the filter and after comparing the results of identical images taken with the same camera using this filter and one of my prized and now unaffordable Zeiss "T" filters, I can say I see no difference can the results. I'm sure an optical lab could document some differences, but in the real world I can't see any differences when comparing the test images I took with this filter and the Zeiss filters I've used. This design works so well that I am slowly replacing the older non-Zeiss filters I have on my older lenses and cameras with these newer designs.

I have no complaints about these filters. I run them on all my walkabout lenses that are carried around. Flare resistance is very good thanks to the coatings, and it's rare that I have to make an adjustment to a shot due to flare. The only exception was when I was taking photos in a museum, pointing up at objects near bright lights. But other than that, they clean well and let me walk without a lens cap for those candid shots.

K&F makes some of the finest UV Filters for the price. The ring also includes groo

Great protection
