Pentax 26725 overview

  • 1Description

The Pentax smc FA 645 45-85mm f/4.5 Lens is a standard zoom lens capable of wide angle to short telephoto focal lengths equivalent to 35.5-67mm in 35mm format. The maximum f/4.5 aperture is constant throughout the zoom range, and it can stop down to a minimum of f/32. This is due in part to a lens construction of 11 elements in 9 groups.

During use, you can switch between auto and manual focus by simply sliding the focus ring forward or backward. It can even focus down to a minimum of 1.6' away. Further benefiting image quality is an eight blade diaphragm that will ensure smooth out-of-focus areas. It also comes with a case and has a 77mm front filter thread.

    Pentax 26725 reviews

    smc FA 645 45-85mm f/4.5 Lens is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from Superb day to day lens I shoot the FA 45/85 on my 645n and it's very sharp for a zoom. This lens gets a 9.33 user rating on the Pentax Forums and deserve every bit of it. The focus is quick, if a little loud.

    Rated 4 out of 5 by from Excellent IQ, high build quality Stopped down one stop, on my 645z I have found this lens to be very sharp at all focal lengths, with a small drop-off at the long end. Build quality is excellent. If you are coming from 35mm, it's big and heavy.
