The other night, I got to play with the Pentax 645D—the one medium format camera that I had personally been waiting to try out for a while. Pentax was fairly popular back in the film days for medium format. Their lenses are well known as well as their bodies. Now that Pentax has entered the digital medium format stage, they have created what I would call quite the competitor and perhaps what may be the best medium format experience I have ever had of all the systems I’ve tried.
