Title: Protects lens, but blurs photos
Review: I got this as a cheapo lens protector - with some UV filtering as a supposed bonus. I liked it - until I just got back from a trip shooting wildlife on my Canon 70-300mm f/4-5.6. All the images with that lens were slightly blurred. Those I focused manually, those that auto-focused, wide-open or stopped-down. Slow or fast shutter, even on a tripod. All detail was blurred.I got home to shoot some test photos, and I found that when I took this filter off, images were perfectly sharp. Look at the fencepost comparison photo I included in the images. All settings are the same between the two shots, just the one on the right is with the Tiffen 58mm UV filter, and the one on the left is without.FYI - I also have a BW 77mm F-Pro MRC UV filter that I tried on that same lens with an adapter, and the images were crystal clear. Tiffen is going in the trash and I'm buying a different brand.
Is the review positive or negative?
