The used Pentax SMC FA 645 45-85mm f/4.5 is a legacy standard zoom lens that’s compatible with the Pentax 645Z. Key features include:
35 to 66mm-equivalent focal range after crop factor
Excellent for landscape and portrait photography
Clutch design for fast autofocus/manual-focus switching
Advanced optical design for high-quality images
Standard Zoom. With a focal range equivalent to 35-66mm after sensor crop factor, the 45-85mm f/4.5 is a high-quality zoom that covers the moderately wide to short-tele/portrait focal lengths. Its range makes it a great choice for landscapes, portraits, or any other type of photography where you’d need standard-range options.
Autofocus/Manual-Focus Clutch. The 45-85mm f/4.5 uses a clutch design to switch between AF and MF, giving you fast access to make minute manual-focusing tweaks.
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.
