Review-
Using this camera for mainly portraiture so I will review it as portrait camera, so far I haven't been able to use this camera for landscapes which I know it will succeed in that form as well. This camera has been used for two professional shoots, one during a quite rainy day which to be honest terrified me, but with the sealing on this camera and the 85mm Art it held up quite well. That leads me to the issue of durability and build quality.
The camera itself is build like a tank especially considering it is only $1200 hundred dollars at time of writing. The fit and finish is top notch, the camera is made from a magnesium alloy and covered in a leather-est type of plastic that has a very pleasing feel. The camera itself is surprisingly light considering it's size, but that pleasant fact is negated quite quickly by the length and weight of the Art Series of lenses by Sigma. The camera is also very well sealed against the elements in the form of a seal around the lens mount and sealed ports as well as the battery compartment which I have heard described as a submarine door, it is a twist lock and seal which has very quality feel to it. The buttons have very solid feel to them and in my opinion is that they won't wear out easily. The dials have very definite clicks and are very well implemented on the body and are easy to reach. As to whether the body is comfortable to hold I had my doubts if it would be comfortable but i was pleasantly surprised as it was very comfortable to hold and shoot even after a relatively long shoot.
