Every so often I see a claim in a lens description: "These scratches don't affect the quality of your photo."
What does one think when writing this type of statement? That you don't see the scratch on the photos? Even if a half of the lens area is covered by scratches you might not see the scratches on the photo.. Well, this is a somewhat rhetorical question: "How do you know that the scratches don't affect the quality of your photo?!" Personally, I would say that all scratches that are within the entire beam diameter used in imaging DO affect the quality of photos. So, the meaningful interpretation of the original statement would be: "I didn't have the way of knowing any better image quality". Would you agree? Igor
