am a photography enthusiast and I often use the reflex not only for passion but also on construction sites for work. To protect the lenses of the best optics, I decided to test this very low reflectance UV lens, which allows you to protect the front glass of the lenses from dust and possible splashes, but also from light accidental impacts that could otherwise scratch the original lens. The filter I bought is 72mm and is perfect on my Tamron 17-50 2.8 that I use a lot. It arrives in a cardboard box inside which there is a semi-rigid box that in turn contains the filter and also a 72mm cap that is really well made and equipped with an orange wrist strap, also well made and convenient for having the cap always at hand. The kit is completed by a microfiber cloth for cleaning the lenses. The frame of the lens is made of very well painted aluminum. Excellent feeling of the material and perfect threading. The response on the photos is excellent: it does not alter the colors and does not create focusing problems, ensuring greater protection of the main lens of my optics. I consider it a good purchase to have greater protection on important optics, especially if used in "risky" contexts. Well-made product and at a price perfectly in line with the general quality of the product: in addition, with the purchase you have a spare cap, really excellent for preserving the original ones and being worry-free.
