Minor scratches will not do what you are suggesting. I my experience, when scratches become significant the cause an OVERALL loss of contrast/sharpness .eg. flare, due to stray rays, but specific halos/glows? Never seen that. What is happening in the shadow areas of your images? Are you getting visible flaring? Does stopping down to the point of getting those scratches out of the optical path change the "glowing" any or make it go away? jco

It seems like a very nice lens. It has to turned A LOT in order to focus, actually the smallest exchange rate I have ever seem on a Pentax lens. Also the focusing is very smooth, thus accurate. Only down side is the rather long closest distance - appr. 4 feet. I've seen some "glow" around white letters on black background (the shots of my AF280T flash), which could possibly be caused by the scratches on the front element (like vaseline at the edges of a filter - David Hamilton-like)o - just guessing, of course. I got this one for 40 USD at ebay - the near MINT ones seem to go for 150-200 USD. It may be a great portrat lens - 45-125 seems tobe perfect for portraits. Also F.4 all the way through the focal range is convenient for studio work. We'll see :-) Jens Bladt http://www.jensbladt.dk +45 56 63 77 11 +45 23 43 85 77 Skype: jensbladt248 -----Oprindelig meddelelse----- Fra: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] vegne af J. C.
