|comment:||Well, this lens has been used on the a200, a33 and recently the a77. So far, this is what I can say about it.|
The IQ is quite nice. I haven't seen much ghosting or CA which is good as at this range, I would expect it. The bokeh is quite nice to use if you stop it one stop down. Iwouldn't say the f2.8 is bad, just not as sharp as you want. The reach helps a lot with the motorsports I shoot with. The weight is quite comforting given it is feels built like a tank.
However, there are quite some downsides as I noted. You need to stop it one stop to be quite sharp. In high contrast locations where I shoot, the AF was quite pathetic. Shots that could have been sharp came out quite soft on the subject compared to the background. It might not be a problem in other locations or with the use of a flash but I highly suggest you test this before you part with your cash. In normal light, it's decent but don't try it in low light as it hunts and hunts and hunts a lot.
Overall, should you buy this lens? Perhaps. But I do suggest you look at what you're shooting and decide yourself. If in doubt, I highly recommend saving more and buying the Sony G-version.
