Hello, in and of itself, this is a perfect product which is meticulously crafted. I have this protective filter for my NEX-5 ordered (49mm). Unfortunately the edge of the filter is slightly thicker, so I can not unscrew the lens at the sun visor. In other filters (Pol, Graufilter ..) this works fine. So I will probably unfortunately the filter return. Who does not disturb can access here as protection ..
