Tiffen 58mm UV Protection Filter

Bought for a trip to Alaska for use on an all in one lens. Saved lens from salt spray and rain throughout, and I would much rather clean the cover than the lens. Shipped fast!

I haven't tested it a lot yet, but it fits perfectly well on my Panasonic Lumix FZ28. The build quality looks fine to me, and the protection against finger prints is all I wanted.

Construction of the filter is great with a metal ring that can protect your glass. However, the product produces a glare. As I found in the reviews below, this it is very apparent for everyone. I tried flipping the filter to see if it made a difference but it did not.
Also, the filter I received has imperfections that are visible under direct light. They show up as shiny specks in the glass. No amount of cleaning would remove them.
I'm returning this because the issues stated above render the product useless. Lesson learned, look at reviews first and like one user stated, "look for Multi-coated."

Great filter to protect my lens, great service and quick delivery. The only problem i had is my Canon L lens will have problems sometimes focusing with this filter on.

Just wanted to warn, that this filter on my Panasonic 20mm 1.7 lens causes a lot of flare. Be aware. I'll likely buy a nice B+W filter soon to avoid this. With any bright light source there is a noticeable amount of flare. Thank goodness with digital you see it before you take the photo!
