Key Features
  • Pentax 645 Mount
  • Aperture Range: f/4-32
  • 35mm Equivalent Focal Length: 96mm
  • Super Multi Coating
The smc FA 645 120mm f/4 Macro Lens from Pentax is a medium format, manual and autofocusing, short telephoto/portrait prime lens that provides a 35mm equivalent focal length of 96mm when used on a Pentax 645D or 77mm on a film 645 camera. The super multi coating (SMC) significantly increases the amount of light transmission. The lens offers a 1:1 magnification ratio and focuses as close as 15.4". The focus limiter can be used to set the focusing distance range for increasing the speed of the autofocus. The maximum aperture of f/4 can be stopped down as far as f/32. The lens was developed using computer-assisted optical design technology for a high degree of precision. It uses a floating mechanism and an independently-moving aperture mechanism. It also features extra-low dispersion (ED) glass to correct for chromatic aberrations, helping to deliver sharp imagery with high contrast and clarity throughout the focusing range.

Has anyone compared this to the older manual ...

Has anyone compared this to the older manual focus 120mm f/4 A lens? I have it and it gives focus confirmation beep, I can't imagine it being much shaper but I don't use it for portraits because I don't want the delay of finding focus using live view and zooming in...
Asked by: Paul
The Pentax smc FA 645 120mm f/4 Macro Lens is improved from the older version, because it has better muticoating on the lens, giving the photographer fewer hazy images with improved contrast and sharpness.

question

Hi there, I am new to Medium Format Cameras, does this lens have Vibration Control?
Asked by: Orighomisan
Shake reduction built into the lens is already old and redundant technology. The newest technology is Pentax's shake reduction done on the sensor instead of the lens. Already rolled out on models like the K1 and KP. Let's hope they include it into the next version of 645.
