The picture is big. This camera shoots frames that are 6cm by 4.5cm in size, which is over three times the surface area of a 35mm frame. That means three times the detail, and three times the control over the exact point of focus.
I loved this camera, and used it until the frame advance motor died. When that happened, rather than replacing it, I "upgraded" from this 1984 camera to the newer 2001 version: the Pentax 645NII. These cameras get a lot of attention online because they are a great place to start with the larger formats, which is exactly what I did.
I highly recommend them if you're doing the same.The Pentax 645 side-by-side with its successor, the Pentax 645Nii
Here's some of my favorite photos shot using this camera.
