At a range between $7 and $10, this is one of the best values and investments out there. What is it actually used for? A UV filter has two primary purposes: to filter out unwanted ultra-violet light and to protect the lens. For most general photography applications, you will not notice the difference in UV light. Only when you have intense sunlight at a specific angle will you start to notice the UV light. It will not alter your photos and their lighting negatively, so you can pretty much leave this filter on all the time. This filter doesn't do that great of a job in actually filtering out harsh light at the ultra-violet spectrum, but if you're an amateur photographer, you won't need that function. If you do encounter a lot of harsh UV light (you live out in the desert or in Alaska), then you should consider a different filter. As an advanced but non-professional photographer who averages 500 photos indoors and outdoors per week, I have not yet encountered any harsh UV light that this filter cannot block. I use this on my Canon 18-55mm f/3.5-5.6 lens, and I pretty much never take it off. This filter will protect your lens from scratches to the glass. When you get smudges (which you will) on this filter, you just wipe the filter or remove it and clean it. It's much easier to clean this filter than the glass on the lens. But the most important part is that this filter serves as insurance for your lens. If something comes flying at your lens, you have a choice of replacing a $7 filter or a $150 lens. It's a no-brainer! Now, this filter is useful for either the amateur photographer or the advanced photographer who has a relatively cheap lens (a $150 lens is considered CHEAP compared to $950 for the Canon 17-55mm f/2.8 IS). If you own a more expensive lens, you'd want to go with a better filter, such as one from Hoya or B+W. But if you own the Canon Canon 17-55mm f/2.8 IS or an L lens, you know that already. All in all, I gave this filter 5 stars because of its great value. If it costs $20, I would have reduced it to 4 stars. Considering its use, you cannot beat this product.
