You must have been stopped down to a very small aperture. If you were using a filter, my suspicion would be the same as Peltigera's--that it was cross threaded.

Getting back to the original problem:
Well something must be out of true, assuming the photo is full frame.
Great shot - Photoshop can rescue those corners, but it would be good not to have to bother.

> olroy2044: "Welcome to the group!" > Stephen: If it is the filter, etc., why is it only on the right hand side? I am assuming that the shot is the whole negative, how was it scanned? But then you say it is confined to one lens, sounds like an element has come loose, or the mount is off the centre line, but either should be very obvious indeed. What Nikon body is the lens being used on? ....I am assuming it is on a non digital body as the shot is in B/W. If the shot is now decent scan, the vignetting marks can be removed totally in Photoshop, or The Gimp. > peltigera: On the original picture - is the filter on cross-threaded? > Wayne: You must have been stopped down to a very small aperture.

I have taken the picture with a Nikkormat FT2, but the Nikkormat FTn produces same results. Here is the lens on FT2: The lens looks almost unused to me, and came from ebay. The seller have a 100% positive feedback, but it could be sold due to a defect not noticeable unless tested? Thanks for the warm welcome, olroy! The scan is not the problem, as this lens only gives this problem. The filter is proper mounted and aligned. The lens hood is original Nikon for the Nikkor-H 28mm. It may be som internal defect, as mentioned (loose element). The lens was stopped down to f.11, it should not be a problem, but who knows. I might have to do some testing without filter, lens hood, trying all apertures and then investigate... I can remove the vignetting in GIMP, as I use GIMP as only photo tool. About GIMP, I also use GIMP as I also are on Linux (since 1994). When I started using GIMP it was overwhelming number of menus/features/choices and it was unfamiliar. Later I started to learn one thing and proctice on this one feature. When mastered, I went on to the next learning topic. Today, I use only a few functions, as the healing tool to correct dust and defects in the photo, cutting and cropping, converting color photo to BW, adjust colors and a few more. Using tutorials is our friend learning GIMP. Users of Mac also can install GIMP. Thanks for all the answers!
