You Pay: $4,296.95
Product Highlights
  • Medium-Length Macro Lens for Pentax 645
  • Fast f/2.8 Maximum Aperture
  • Quick-Shift Focus System
  • HD and Aero Bright Lens Coatings
  • Weather Resistant Construction

The Pentax 90mm f/2.8 D FA 645 Macro ED AW SR Lens is a fast, medium-length lens (equivalent to 71mm in 35mm-format) for use with Pentax 645-mount medium format cameras. The f/2.8 maximum aperture provides greater control over depth of field and features rounded 9-blade diaphragm construction. This lens has the Pentax Quick-Shift Focus System for rapid switching between auto and manual focus modes, and integrates a Shake Reduction mechanism for countering the effects of camera shake or image blur.

Both an HD Coating and Aero Bright Coating are applied to lens elements in order to improve overall light transmission while reducing flare and ghosting. A Super Protect (SP) coating is also applied for protection against the elements and to ease cleaning of the lens. In addition to the SP coating, the overall construction of the lens is also weather resistant and dustproof.

Compatible with Pentax 645 AF2 lens mounts.
Medium portrait-length lens is equivalent to 71mm in 35mm format, giving a slightly longer-than-normal angle of view.
Fast, bright f/2.8 maximum aperture helps control depth of field and enables greater versatility when working in low-light conditions.
Quick-Shift Focus System allows you to instantly switch between auto and manual focusing modes.
HD, Aero Bright, and SP coatings help to improve light transmission, reduce lens flare and ghosting, and aid in greater protection for the lens surfaces.
Dustproof and weather-resistant construction provide increased protection when working in poor conditions.

          Comments about Pentax 90mm f/2.8 D FA 645 Macro ED AW SR Lens:

          The more I use this lens, the more I like it. While it took a small amount of learning curve to figure out the Pentax 645Z, the use of this lens surely helped. It is tack sharp and compares favorable with my Canon 85mm 1.2 as well as my Canon 100mm Macro lens. Ive used it with and without a Polarizer and looking forward to testing it with ND Filters. It is considered heavy by some, but Im use to the 70-200, seems about the same.

          Comments about Pentax 90mm f/2.8 D FA 645 Macro ED AW SR Lens:

          I have had the lens for approximately one week, and so far I have been quite pleased with it's performance especially at f2.8. The software upgrade to the camera was strait forward with no problems encountered.
          The anti shack system works well but can not be used in combination with HDR. At first I thought something was wrong until I shut off the HDR.
          The auto-focus did a lot of hunting, but in close up work focusing manually
          is the best way to go.

            Comments about Pentax 90mm f/2.8 D FA 645 Macro ED AW SR Lens:

            I can't speak for its macro abilities (as I have not tested them), but this 90mm is in the same category with the other absolutely recommended lens for the 645 system, the 25mm f/4 AL (IF) SDM AW. Both lenses are pricey, but well worth the investment, as they won't disappoint. Both offer fast and accurate focusing, as well as amazingly detailed images. The silent built-in image stabilization works well, adding about 2 stops advantage in real world applications.
