This lens is so good I bought a second one to keep with me! Seriously, I've had a lot of lenses, but this one gives the sharpest image for its size and weight. Of course there are even sharper lenses available for Sony, but due to their weight you won't be lugging them around all day on vacation. What other telephoto lens delivers the sharpest images at the long end? Canon L lenses definitely do not fit! I would highly recommend this lens to anyone looking for a sharp, compact and lightweight…
