Rocketfish RF-UVF55 UV Lens Filter
I purchased this to protect my Sony 70-210mm lens. So far the clarity is great and it doesn't add much noticeable distortion to the photos. It was much cheaper than the alternatives. Though it is not the best quality you can buy, it's close to the best for this price range.
This is a must have to protect my lens from dust or damage. This is a replacement filter glass for one that I broke when I accidentally bumped the lens into a doorway frame. My fault so the cost of the lens filter saved me a ton of money in a replacement lens. Is totally worth the price.
I'm always skeptical when buying something so cheap but, this works exactly like it should. No distortion and it keeps my lens clean and dry.
Ordered the wrong size but made use of it with another project
The filter is fine and arrived in perfect condition, however I ordered the wrong size. For a 55mm lend you need the 52mm filter not 55mm. Otherwise, the product itself is fine.
It is serving me good.
