I am currently looking for a single lens that I can carry for landscape photography and someone has offered a reasonably good price for the Canon 28-300 3.5-5.6 L. I've checked the samples here at the forum and they all seem to be not as good as other Canon L lenses in terms of sharpness, color and contrast.
I'll be shooting mostly F5.6 and about so the aperture doesn't bother me.
Any feedback on this lens please? Any alternatives from 3rd party vendors?
