Its a UV Filter. Works as expected. Clear glass no anonalies in the surface protects the new Pentax 50-200mm Zoom I purchased well.

Tiffen filters are always reliable; they're the only ones I use. 

Tiffen 49mm UV Protection Filter

It's a Tiffen 49 mm UV filter, an industry standard. No magic here, it just works.

Nice uv 62 mm lens. These lenses will protect my lenes. Great price good quality,

This morning, my camera fell and hit pavement directly on the lens.I had this UV filter in a closest since 2011. For some reason, two weeks ago I stuck it on my Sigma 30mm.The glass on the UV protector shattered, but the lens seems fine. It took me a while and some serious force to get it off because of the impact.I just ordered two more.

its a simple kit for my budget works great with my t4i EFs 18-135mm STM lens . I use the UV filter to protect my Lens from scratches and finger prints, dirt and sand.

Zeikos ZE-FLK58 58mm Multi-Coated 3 Piece Filter Kit (UV-CPL-FLD)









Nice lens filter kit. Contains a good assortment of much needed filters, including a clear UV for all-time lens protection. I bought the 67mm for my Nikkor lenses and feel they're an excellent buy for the price. "Name brands" are a lot more expensive and really don't provide much more to compensate for the difference in prices. I would definitely buy these again!

Had tried another UV filter that I had got free with the lens purchase on my Sony FE 4/24-105 G OSS lens and found that it was causing some vignetting even though it was a slim filter. Did some research and came across a site that did extensive testing of UV filters that were priced cheap to pretty high and the reviewer there too said that he was very surprised at how good this Hoya 77mm HMC UV (C) filter was and is one of the best even when compared to the pricier filters. I have used this very same filter (albeit 72mm) on my Sony 2.8/16-50 SSM lens used on my A77 camera and never had any issues or complaints.Based on my personal experience and the review I mentioned, I bought this filter and was not disappointed. It did not cause any vignetting and the images are sharp and though it is now said that a UV filter is not really required for digital cameras it just feels safe and not much of an investment to just have it on for a peace of mind that the lens will be generally protected from minor nicks and scratches. Though this can be easily achieved by just having the lens hood on at all times.Well all that said and done, I'm going to have this on my lens forever!
