70-300mm telephoto zoom comp page.

A quick comparison page has been posted with the usual boring, but still useful stamp crops, put
side-by-side, for those interested in the Tamron or Sony 70-300mm telephoto zoom lenses.  Both lenses have their pluses and minuses as far as sharpness goes, it all depends on the zoom setting and aperture.  The Tamron is a little longer (things are closer) at all focal lengths than the Sony, but not enough to notice unless both images are directly compared.

I always try to warn people about placing too much emphasis on sharpness.  Accurate AF, focus hold
buttons and focus limiter switches can be very important in action related photography.
