Ricoh's Pentax 645Z offers a level of consumer-friendliness previously unseen in its class. The 50MP CMOS medium format sensor is complemented by a number of features from the K-3 DSLR, including a 27-point AF system with 25 cross-type points. It can even record 1080/30p HD video with stereo sound. We've added it to our studio scene tool so you can compare its results to the likes of the Nikon D810.
