When it came I noticed the "Sony A33 / A55 compatible" sticker and thought to myself: great ...
Unfortunately, there seems to be a later update from Sigma, because on my A99 & A77 of AF was not working. So I convinced myself first by MF of the image quality and chose then the lens to send the update. Although annoying, but because of the unbeatable price on Amazon I have accepted. Even more annoying: I had to pay for the shipping of Sigma (despite warranty !!!)
But the objective it was all worth it. The picture quality is brilliant, even at full frame. The AF is very accurate and had to be adjusted to any of my 2 Bodies.
The case also makes a high impression. In addition, it has 3 years warranty.
My conclusion: Those who do not want to necessarily make the Zeiss, who can confidently pick up the Sigma. According to tests, the Sigma is the Zeiss eh after in any way. Therefore, full 5 stars. The service provided by Sigma I would give only 2 stars.
