I have these on at all times because they barely darken anything. Meaning high light transmission. I had to really look at some scopes to find a difference. I gave up and just assumed any light loss is meaningless. For sharpness, stopped down in the sweet spot with the new Sigma Art lenses, I can't tell a difference on my 42 mp camera. My Tamron 35-150 is pretty much perfect for 42 and 61 mp sensors, and its the same. Even the g masters my friends have shown it is pretty much the same with or without it. But, I can tell better contrast and micro contrast with landscape and city shape. It's basically dehaze in camera. And, a bit of clarity. I have had photography friends what I'm doing in editing to get clearer images, and it is using these and a cpl if I need to. Also, my lenses are expensive. They're insured but I would die if a front element got scratched. I work a lot of events and shoot video in weird places. Many years ago, I did actually trip and my Sigma 85 hit a rock. I didn't want to look. Luckily the lens was perfect and this filter took the hard scratch. Ever since, I buy knf concept nanox uvs for all my lenses. I spend the bit of extra money because the lens sharpness is intact. Color is all there. Dehaze in a filter. And, if a tragedy were to happen, I am out like $40 over $2,000. Or waiting forever for my replacement and insurance claim to go through. Read more

Unlike some people I believe that a UV filter is a must on a lens for the protection it provides and for the ability to decrease atmospheric haze and glare. But having said that I also believe that the filter must be of high quality with good coatings so that it does not negatively impact your photos. I think that this filter meets these requirements. I have run some simple test taking the same photo with & without the filter and see no negative impact from the filter. The filter is also a good quality filter from a construction perspective and I see it lasting and providing a useful function for a long time, and for a good price. Read more

Best bang for the buck. Using with Sigma f/1.4 16mm. The absolute best is from Breakthrough Photography. Be ready to spend 4-8x for marginal improvement in IQ. Read more

Great filter for protecting expensive lenses. My previous filter cost twice as much as this one and actually was a great filter but it didn’t have scratch resistant coatings. Over the course of a couple of years the lens cap actually scratched the old filter along the edges. This filter has the anti scratch protection the other one didn’t and it has anti glare coatings as well. I am unable to detect any difference between images taken with or without the lens filter. Some people prefer to shoot without filters in order to capture the best possible image. I prefer protecting a $1600 lens with a filter that doesn’t affect the image quality in any way I can detect. The filter came with a nice container as well as 3 micro fiber lens cloths. It’s a mid range priced filter and I’m happy with it. Read more
