Maybe it's the subject matter or just my eyes, but I seem to detect a
bit of image degradation at the edges and corners. Not a lot different
than the FA 28-200mm. I don't think I'd want to use the DA* 60-250mm on
film, ( or a 24x36mm sensor if or when it becomes available on a K mount
body), if critically sharp imaging was required, (not that it would
actually be worthwhile on any of the Film cameras I still own)..
It's a single web image taken and processed under unkown circumstances. As an
evaluation tool (unless you are using it to evaluate how that image looks on
your monitor) it's about as much use as a fire extinguisher filled with petrol.
I believe the image was only intended to show the extent of light
falloff in the corners at max aperture and minimum focal length. It's
adequate for that (unless one is given to conspiracy theories and
suspects Photoshop manipulation and such).
There's no denying that the image circle covers the 24x36mm format,
however there have been lots of lenses made that cover formats larger
than they were intended for. The question is does it do it well. Based
on my view of the sample I'd say not really. Look I'm not saying it's
a bad lens. I'm just saying don't expect it to be better than advertised.
