This filter came elaborately packaged suitable for gift giving. It also looks great with a gold colored inlay showing its pedigree. Please see the image that’s part of this review for a look at part of the gold colored lettering.It sure does look the part. I tried some test shots with the filter on and off the lens and then did the best pixel peeking I could noting no difference in exposure or color cast. To be fair, I’ve never noticed this with any high quality filter. I’ve never bothered with bargain basement filters because I have no interest in Lomography or its related ilk.The manufacturer says this is thin and it is. Please see the image where I compare this filter with another UV that costs less than half as much. Both seem thin to me. I don’t see how thickness makes that much of a difference because adding any filter will require the removal of this one or you’ll get image quality robbing refractions from between the two filters.I considered using a micrometer to measure the thickness of the lens itself but gave up the idea because I had no way to assure that I’d not scratch either this or another filter I’d use for comparison.In sum, this does work well as a UV filter and it does not in any way alter the images when compared to the same lens without this filter attached.

This is a very nice filter but is a bit pricey compared to others from K&F. This is very thin and well made but doesnt offer as much as say their CPL filter does. This doesnt have the same grip and texture though thats probably due to the slimness. Of the higher end filters K&F makes I dont see the same aesthetics with this one. Optically this still performs well.

 The lens looks and feels nice. It seems to be of good quality and would last longer. The storage case looks elegant and comes with a wipe to clean the lens. The few pictures I have taken seem reasonable, and the lens doesn't cause any issues with the quality.

Got this to combo with my Canon R5 and the nice all-around RF 24-105 4 L lens. Fits nicely, and the lens cap is secured. Its UV protection is a nice feature to have. It keeps my pictures free and clear from those pesky UV rays when taking pictures outdoors, especially at the beach. My kitty ended up being the celebrity for the day while we were getting some sunshine hehe. Definitely worth getting, especially for anyone doing outdoor photography with the 70-200 2.8 L lens or 24-105 4 L lens (77 mm diameter).

K&F’s build quality has been second to none in the last several years. They’ve created a series of extremely high-quality filters using very slim precision machined brass rings ( brass is a much better material to use for this purpose than aluminum. It’s much less likely to strip threads or to cross thread) and excellent optical glass.This filter is no exception. It has absolutely no optical distortion whatsoever. It filters UV and pretty much nothing else I think it has about a 99.9% visible light transmission.Most people use UV filters to protect their lenses but it’s also helpful to filter out UV light for photographic reasons. It can help to increase the life of your camera sensor and prevent distortion in the images.The anti-reflection coding on this is extraordinary. This competes well with my expensive high end German filters that cost up to four times as much money.This filter is slim enough that it should not interfere with the image or create any vignetting even with wide-angle lenses.This is my review for the UV filter but honestly every K&F filter I have purchased has been extraordinary.Look at the photo and see if you can tell any difference.

This new line of pro grade filters from K&F Concept is truly fantastic.These filters are super slim, with smooth threads that attach easily to my lens.The UV filter doesn't have any color cast or produce any optical aberrations in general.Just a crystal clear filter to keep your lens safe.Comes with a padded case for safe storage.

I like to use UV filters for lenses that aren't in the studio enviornment. Nothing sucks more than having the elements contimanate your lens and having to hault the shoot to fix it. The major downside to this approach is the bulk and loss of image quality with inexpensive UV filters.This filter perfectly addresses that need. It has a very slim profile that is barely noticable - yet still functions great for attaching the lens cap. The small profile also produces less distance between your glass and the filter.I haven't noticed any ghosting, chromatic aberattions, or other distortions from using this filter. This is very rare - and marks the K&F as a winner in my book.

I have had many UV filters from multiple brands. This is now one of my favorites. It is exceptionally clear, light weight, and well built. The included storage case is also top notch. I'm going to have the leather flap labeled with a laser. The box converts into a picture frame which is oddly cool.

67 mm fit just right on my Tamron. If you use an expensive lens, I recommend getting one of these to protect the glass.
