I bought the Tamrom filter as protection for a high-quality Nikon lens. Even the packaging is clearly different from the "hama" -üblichen Blister: The cardboard box itself is a stable plastic box, in which the filter rests on foam. So it can be (if it is not to remain permanently on the lens) comfortably and safely transported in the camera bag.
The coating is free from defects, the quality of the images suffer in any way if the filter in front of the lens. Strong buy recommendation, I would at any time prefer the comparable Hama products against.
