This review is for: K&F Concept 72MM UV Filter — HD Ultraviolet Filter Scratch Resistant Lens Protector Filters with Lens Cap, Cleaning Cloth for DSLR Cameras (Nano-X Series). While UV filters are helpful in film photography to remove color casts, UV filters are no longer necessary for the image quality of most consumer digital sensors because a UV filter is installed in the sensor stack (unless modified or made for astrophotography). On the other hand, UV filters are also commonly used as lens protection for digital devices. Although I don't usually leave protective filters on my lenses, I do use a UV filter in adverse conditions (wet, dusty, dirty). This filter offers excellent transparency: - I can't see any anomalies in the glass - No noticeable degradation in image quality - No noticeable discoloration - Low reflectivity coatings designed for easy cleaning and scratch resistance - Well-shaped ring and threads - Satisfyingly thin form factor - Nicely anodized ring - Knurling aids in installation and removal - Hard case - Add 72mm lens cap, lanyard, and microfiber cloth Value Misses? - There is no label on the filter case. Since I don't like carrying boxes, I make my own label. - The filter case is a bit large since it is designed to hold the filter with the lens cap installed. I usually look for ways to make my kit smaller. - The added items detract somewhat from the value proposition if you are just looking for a good filter. No major misses, but worth pointing out. I have had several K&F products over the years. Well designed and with great attention to detail. The quality has never disappointed me. This is no exception. Worth considering. Recommended accordingly.
