Its large aperture allows make beautiful pictures in almost any situation, his ring to attach it to a tripod is very well designed and provides good support in hand, facilitating the use of focus and zoom rings. If you do not have a "full frame" sensor does not forget that it will turn into 70-200 112-320 on an APS-C sensor for example.
The objective is really fast in focus despite my little Alpha 33 ... The development is extremely quiet and smooth. Its finish is excellent. This lens enables manual focusing even in AF (AF resume although the top, we can help or simply try different developed without having to disable AF).
Not knowing before you buy: This objective has fixed dimensions, no external part of the goal is moving in the autofocus and lens does not extend to zoom in, everything goes inside.
In short, I recommend it openly!
However remember that it is not stabilized!
