I have been looking at possibly getting one of these two lens, the Sigma 50-500 OS DG APO HSM or the 150-500 OS DG APO HSM for some wildlife photography. Now the 50-500 is a 10x zoom lens, so I presume that some image quality (sharpness) will disappear at the far extreme ends of zoom, whilst the 150-500 is only a 3.3x zoom, which should be better throughout its zoom range.
So my question is, has anyone had experience of both these lens, as the 50-500 looks more useful, but if image quality suffers (especially at the 500 end) then I would go for the 150-500 as it is a lot cheaper anyway.
