After investing into the sony e mount range, this lens was my next step. My wife covers me in shooting the 24-70 nikon, and she wishes to stick with it.
This lens creates the best images from a 70-200 lens I have ever seen. It is only after using this lens you sense an anger towards canon and nikon for the lack of innovation and groundbreaking technology sony has managed to conjure.
The bokeh is pleasing for a 2.8, the lens is sharp!
It is on the heavy side, i may suggest using some form of strap attachment to the lens because I have heard of one sony strap ripping off due to the weight of this lens from a user.
The autofocus however leaves a lot to be desired, you need to know the limitations of this lens although eye af helps, out of 20 fast moving shots, around 6/7 will be in sharp focus and an extra 4 maybe can also be used. With the nikon I know I nailed the shots pretty much 99 percent of the time.
Also this lens has a tendency to hunt, it is not a quick lens by any means, hence you have to know its limitations. I would rather use a 85mm batis with a bride walking down the aisle then trust this lens.
Buy but be aware, although it produces the best images you will see, the af is slower then nikon/canon systems!
