Using this filter on a Nikon 16-85mm lens causes lens flare when a light bulb is in the frame. Lens flares were clearly visible with the filter. No flares occurred without a filter nor with a multi-coated filter of a different brand (which happens to be less expensive).
I haven't tried this filter with any other lenses or very many lighting conditions so I am not sure how widespread this issue is. The glass clarity is good, but the flares can be very distracting.
Lens Flare with Filter
Tags: Made with Product
The first accessory I buy when I get a new camera is a glass UV filter. I wouldn't be without one. Not only does it give UV protection for my photos, but it also provides considerable protection for the front on whatever lens I am using. I always have one permanently on each of my lenses. This is the first B+W brand filter I have bought and it seems to do a better job with UV than the less expensive filters I have used in the past.
When I purchased my Tamron 17-50 f/2.8 lens, the salesmen recommended that I should purchase a uv filter for it. It's purpose is to protect your glass from the elements, and it does just that. The filter comes in a little plastic case w/ cushioning. The ring seems to be made from metal and it feels sturdy and strong.I would purchase from B+W again.
