My first post ever!
Manfrotto Outdoor UV Filter 58mm
A decent price for quite an essential piece of camera hardware.
Most places sell it for $20+ not including delivery so this deal works out pretty good.
Not much info on the TVSN website so I'm not 100% sure what the exact specs are.
Says it's a clearance item so stock will be limited.
No need for a UV filter if you have a digital camera, and if what you really want is a way to protect your lens it's arguably better to actually buy a purpose-built clear glass lens protector that will likely be quite a bit tougher than a UV filter. And if you feel the need to do that nothing less than a high quality multi-coated protector will do if you want to minimize optical degradation and reflections.
Personally I don't use any kind of filter, on any of my lenses, unless I am trying to achieve some particular effect. So I don't see them as essential ever-present additions at all.
Each to their own I guess.
