These digital cameras filter are used to alter the properties of light as it enters a camera's lens. This process is meant to improve the quality of the image as it is recorded by altering things like the color, contrast and sharpness of an image. High quality optical glass for maximum clarity and vivid picture and camera lens filter absorbs ultra violet rays without an increase in exposure to provide a clearer picture as well as protection for your valuable lens. A digital cameras filters serve to protect your lens from all dust, dirt, scratches and fingerprints. The camera lens filter also absorbs the ultraviolet rays of the sun thereby reducing or eliminating distortion. The ultraviolet-blocking filter effectively reduces or eliminates photographic haze in areas where the atmospheric conditions contain a heavy concentration of dust particles, water droplets, and pollution. The 58mm UV lens filter filters out ultraviolet light enables the capture of vivid colors and sharper detail.
Pros:The primary purpose of the filter is to protect my lens from dust and scratches. The filter is a very good quality glass and does not compromise the image quality. I have bought three as it is better to damage the inexpensive filter than the lens.
Other Thoughts:This is a nice protective filter. It's not really a filter it's to protect your main lens. Very clear, I can't see any difference in image quality. Screws right on to my fz100 lens and I can still put my lens cap on. I would definitely buy this again.
Other Thoughts:This is just your basic protective filter. It is not multicoated but you can also wash it, wipe it with your shirt and do whatever else without damaging it. I will not de-rate it because "oh, it is not as good as a Hoya Digital" because, well, it isn't and it is not priced as such either. You get a decent protective filter for fifteen bucks, if you need multicoating - buy a different filter.
<br/>I use it in place of a lens cap and will remove it on occasion, shooting into the sun, to reduce glare. In 90% of what I photograph, it is not noticeable. I also read that Tiffens are pretty tough mechanically but I did not yet have a chance to find out.
<br/>The threaded ring holding the glass can unthread a bit with use. Just tighten it with a pointed object if it does.
Other Thoughts:I have this on my Lumix FZ35. For those of you who are not sure how it fits on, it screws into the threads on the inner lens barrel. I took two identical shots inside at full zoom and noticed a slight difference in brightness which is expected. At the lower zoom levels, it is very difficult to see a difference. This is really beneficial outdoors but if you are like me, you want something you can just leave on there to prevent dust from getting inside. You can't go wrong with this especially for the asking price.
