Standard Focal Length. With a focal length equivalent to 59mm when used on the Pentax 645D and 645Z, the 75mm f/2.8 is a great normal range lens for general use. It produces high-quality images, with a fast f/2.8 aperture for pleasing subject/background separation.

Please Note. This is a legacy lens that was originally designed for medium-format film cameras. We’ve noticed that it tends to slightly front- or back-focus, so you’ll want to make sure you microfocus adjust before you start shooting.
