    The aberration should appear in the viewfinder, but of course it'll be small. Hmm, disasembling the lens doesn't sound promising though....

    What kind of lens/camera is it?

    Nikon F100 shot through a Nikkor 28-70mm f/3.5-4.5.

    Ah, crap. I've noticed that the rear lens element (the part that slides in and out with adjustment the zoom ring) is a little "loose" on the wide end of the zoom and it jiggles a bit inside the lens. Since I was shooting these inside the cramped quarters of a semi-abandoned building, all of the photos that I took on the problem roll were at or around the wide end - 28mm. Could the loose lens element be causing this? If so, this may just be a matter of tightening some screws.

    Did you get a CD of the scans which were used to make the prints? If it's the lens, then the problem would also be on the scans of the negatives.

    Good point, but unfortunately I was going for the cheapest workable develop/print solution, so I opted out on the CD.

    I guess the ultimate question here is whether or not the chromatic aberration could be caused by a mistake or two in my disassembling/reassembling of the lens and/or a loose rear lens element (not sure if that's the correct terminology)...

    The lines are too sharp to be chromatic aberration. The colour isn't quite what you see in chromatic aberration either (though that's hard to judge through a computer image).
    I wouldn't think the lens is at fault.

    It could be something you did, sorry to say, but if you have some way to print or scan your negs yourself that would be very helpful. Then you would know if it is a lens issue or just poor printing on their side. All machine prints these days are from scans so there are two ways things can go wrong on that end.

    I sincerely hope you're right. I'll post a couple more examples soon.

    Trust me, I would give anything for the negatives right now. They're still in Chicago where I shot the roll and had it developed. I'm at college in Missouri and I had a friend send me these after a short visit up there - unfortunately he forgot to drop the negs in the envelope. I'll check them when I return in a week but until then there's really no way for me to get my hands on 'em. I have another roll shot that I could have developed at an actual photo shop in town, but it's B&W, so the results probably would not be very conclusive.

    Here are more examples as promised:






    The original, for scale:


    I don't exactly have EXIF data but I can tell you that all of these were taken w/ my Nikon F100 through a Nikkor 28-70mm f/3.5-4.5 at around f/3.5 in about 1/40 or 1/60. The film, again, was Fujicolor C200.

    Tough to tell, too bad about the negs. The fringing does seem sharp, but there is sharpening that is applied both in scanning and in printing so it's hard to judge. The B&W still could tell you something, if it is the lens it would show as softness, something like a "glow" that true soft focus lenses give. If nothing else, you would have some negs to look at, so you can eliminate any digital effects. Eliminating digital, what apug is all about.
