I use this lens on my A99, and shoot it at f2.8 or 4 whenever possible. It's tack sharp, from f4 on down, and f2.8 is as sharp or sharper than either the new Canon or Nikon 24-70 f2.8. This is also an excellent portrait lens for in the field (I use its shorter Zeiss counterpart in the studio), but it is large and heavy. The color rendition, contrast and sharpness of this mid-tele rivals that of several primes due to its new coatings. Flare and CA are non-existent. The weather-sealing is excellent, and tempts you to take it into the rain-forest (and make you trek with it for hours) for some awesome images. The autofocus is silent and near-instant, great for sports tracking, hot-air balloons, concerts. This is a top-notch hunk of glass that will render images as well or better than what you can imagine, but it is very heavy. Exceptionally well made.
