Hi everyone,
Im looking for some input, where possible.
Ive come across this intermittent phenomena whilst using a recently purchased Canon 70-200mm f4 (non IS) lens. (see dark edge/shadow/smudging to outline of flowers) It seems to happen in harsh light, where white is against a darker background. I have images surrounding the one above that do not carry this issue. Ive also seen a slight paler edge as above on the top of a Gulls head (in dull light) and against a darkish green background. (see attached image)
Does anyone have any experience with this? Is it a form of chromatic aberration or something to do with the Camera image processing or sensor? I must admit, Ive done a few test shots, unfortunately all indoors, and have not seen the problem occur when the lens was used with my 50D. The above image was taken using the 1DMK2N. Im hoping to try the lens with both bodies, outdoors, later today!
I must add, the vast majority of images taken with both the 70-200mm and 1D body, have been fine; im just slightly unsettled by the above occurrences.
Ive done lots of searching, but cannot find anything to replicate the above. If anyone has any idea or clues as to what could be happening, I'd love to hear; particularly if this is either a lens or camera issue.
Exif data is included.
Tripod used
1/800th sec
f/5.6
ISO 640
Spot Metering

No post processing
Best wishes and thanks,
