Just do not buy! 4

Property me this filter as a protection, and of course bought as a UV filter for my Tamron VC 70-300DI USD. The lens is really awesome for its price, which is why it has then surprises me more and more over time, why I am so dissatisfied with the image quality. My friend brought me to the idea of ​​time to make comparative photos - with or without the UV filter (same aperture, same exposure time, same ISO value.
The loss in the imaging quality of the lens with a filter were enormous. Far too strong Farbverzeichnungen, and a huge decrease in sharpness. The part ends up with me in the garbage.
Compare pictures will follow.
A lens is now times only as good as its worst lens ... But it has so enormously bad effects, I would not now expected. Especially not with mostly good reviews. Have learned from it, anyway.
