The main aim of using a medium format camera is to produce higher quality images than is possible with a small format camera and the Pentax 645Z certainly delivers in this respect. Images have a superb amount of detail and colours are generally natural, yet vibrant straight from the camera. As mentioned earlier, you need to keep an eye on the exposure when there are bright areas in the scene, but that well within the capability of the type of photographer who will be attracted to the 645Z.
Another benefit of having such a large sensor is that it's possible to restrict depth of field dramatically. This is immediately apparent as soon as you start shooting with the 645Z and many photographers will find that they need to use smaller apertures than they are used to in order to produce a wide enough sharp area.
It will be very interesting to see how the 645Z sells, especially now that we have tiny full-frame compact system cameras like the Sony Alpha 7R and versatile high-resolution SLRs like the Nikon D810.
