Top quality glass at a bargain price,
Verified Purchase(What is this?)
This review is from: Sigma EX DG 77mm Digitally Optimised UV Filter (Electronics)
This brand and variant was recommended to my by a Nikon Main Dealer when I recently bought a new Telephoto-Zoom. Cheaper here than some High St stores by a factor of 3 or even 4. Simple to attach, you just need to be careful that adjacent surfaces are properly clean and then avoid attaching your filter in a dusty environment Very highly recommended.
