Great value in a protective UV filter. This lens appears to have a reasonably high quality ring with a very clear optic glass filter. I have not been able to detect any image degradaton with my Sigma DP2M. Light transmission seems excellent but I haven't tried testing for this. Seems to be excellent value.
A good UV filter that functions well and provides good lens protection in harsh conditions such as field work.
I mainly use it as a lens protector and it hasn't failed me yet. My camera gets banged around alot in crowds shooting in the city and this has protected my lens.
