I'm starting to get (or, more likely, starting to notice that I'm getting...) green and red fringing on some of my shots -- especially on the edges of white areas, and on the periphery of pictures; and I'm worried that it might be my camera, rather than my lenses (which is what the research I've done on the web so far would actually suggest -- so I'm probably just being paranoid; and should probably just accept that this is what happens unless one pays serious money for lenses...).
See here for an example (...look at the window-frames to the right of the photo).
I have a Nikon D200, and I've noticed the fringing using two lenses, so far: my Sigma 18-200mm f/3.5-6.3 DC and my Sigma 28-300mm f/3.5-6.3 DG Macro. Interestingly enough -- well, to me, anyway... -- is the fact that the shots that I've taken that prompted me to post this have all been taken on incredibly bright, sunny days, with lenses with quite a large zoom range....
I've yet to do more extensive testing; but I will go back and try some more lenses (e.g. my Tamron and Nikkor ones) in similar conditions, and then report back: but I just wondered if anyone here had any thoughts in the meantime....
Thanks for listening...!
