Unfortunately, this objective worked anfänglichs not on my digital SLR. However, could be seen on the HP of Sigma, that this technical issue is resolved FREE. So sent there the lens and after 3 weeks I was able to take pictures without any problems with it. Service I can be described as good and competent. The lens hood is included as a standard. Due to the relatively high light intensity, it is quite possible to take pictures without flash indoors. The autofocus works precisely, the image quality is expressed in grades with "2" to indicate. Conclusion: A good everyday lens without special strengths and weaknesses. Value for money: very good
