Im using it on my Nikon 28mm f/1.8 and Nikon 85mm f/1.8. Same diameter on both lenses.

This UV filter has been a great addition to my Tamron 35mm for my sony. This filter is definitely more of a protector than a modifier at least in my use case, it helps to protect the exposed focusing mechanism of the lens and makes sure that no dust or particulates get into the lens. Overall I would say that this is a great filter to put on any lens as it adds a barrier between the front element and the world, and I didn't notice any negative effects on image quality by having this filter on the lens.

I use a Nikon D3100, I bought a Nikon 50mm f/1.8D AF Nikkor Lens. That lens has 58mm threads. I bought the 58mm Tiffen Circular Polarizer filter to use on that lens. At the time of my order it was sold and fulfilled by Amazon. I paid for shipping and received the filter in less than four days. The filter came in a hard plastic box that I use for storing the filter. It looked new and works fine. No filter problems and I give it 5 stars. The only issue is screwing it onto the lens is a bit tricky because you only have half the width to work with but I blame that on my fingers and lack of any real nails. I have noticed that if the filter doesn't go on straight it may make a glare effect but when I see that, I rescrew it on and that takes care of the issue.

Inexpensive filter protection for my 85mm lens. Fits perfectly!!!

I do not use these for the UV filter but as a good quality, low cost lens protector. That said:My 1st Tiffen was a 55mm UV Protector I got for the kit lens that came with a Sony a7ii; an FE 28-70. I was so happy with the purchase that I have since purchased three additional Tiffen UV Protection Filters. One is on a Sony E 55-210 I bought used and one is on a Samyang 35mm I bought new. The one I am writing this review for I assume is still on the Sony FE 50mm I bought new but returned and forgot to remove the filter.The point? I treat my lenses, new or used, like I treat a cell phone. That being the phone stays in the box until I have a protective case for them and lenses stay in the box until I have a protective filter to pair them with. And the one I forgot to remove from the returned lens? That is how confident in the Tiffen filters I am. Once I put one on a lens, I never need to think about it again.I have used several brands in several sizes ranging from the cheaper Altura and Polaroid to the mid range Hoya and B & W.Where does Tiffen fit? Well they are no Hoya or B & W but I am no professional photographer. I am an amateur who mostly enjoys street photography when I travel and for my money Tiffen is the best. Yes, you can spend more and get better glass and if you really have reason to worry about ghosting you should look for a higher end lens. That isn't me saying ghosting has been a problem for me. I normally use a lens hood and I think that helps cut down on light reflection. I have noticed some minor issues with it on some shots I have taken in direct bright light conditions but not enough to justify the higher price.I do not stack filters as I haven't had a need to so I can not give an opinion on that topic. I would assume that the risk of ghosting would increase.The short version is this. The Tiffen UV Protection Filter is well made with good quality glass and a metal ring with threading I do not worry will cross thread or strip. They do what I need by protecting my lens. If I was buying a ND or polarizers I might buy a more costly brand but for everyday protection, Tiffen is all I need and the best for my money.Tiffen say it best in their own product description; A small price to pay to protect your investment.

Fits right in to my Canon 17-85mm IS USM lens. Does what its supposed to do without any degradation in image quality.

Amazing colors and smooth picture quality with the Sony a7iii and Sony 85mm f/1.8 lens

you get what you paid for. It's not a product like B&W.Wonderful for sony zeiss 55 1.8. I touched the glassed in the lens and made some scratch and then decide to get this one. This filter can really protect the lens from unintentional touch.
