+: Perfect fit and protects the front lens
-: Imaging performance of Objetivs leaves more than noticeably
Ghosting / distortion when zooming in on the PC and you
visible on the camera screen clear.
So it is clear why other filter brands are much more expensive and the photo quality
not (so strong) influence.
No Star can not forgive you, so 1 *
For me a clear: No thanks!
