Upgraded image quality by applying the latest lens coatings
The development of this new lens was based on the smc PENTAX-FA35mmF2AL — a very popular multi-purpose, wide-angle lens used on film-format SLR cameras — while conducting a thorough review of lens coatings.
The high-grade, multi-layer HD Coating has been applied to the optical elements to produce high-contrast images with edge-to-edge sharpness and free of flare and ghost images; the highly stain-repellent SP Coating has been applied to the front surface to improve the lens’s usability in outdoor locations. The exterior has been totally redesigned to match the design of latest PENTAX K-mount digital SLR models, while its compact, portable body makes it a perfect everyday-use lens.

About Focus Function
Autofocus is activated when combined with a camera that has an autofocus function.
- = Autofocus driven by the supersonic motor in lens body
- = Autofocus driven by the DC motor in lens body
- = Autofocus driven by the pulse motor (stepping motor) in lens body
- Body AF
- = Autofocus using the motor in the camera body
*The autofocus on a body AF lens operates when paired with a camera equipped with an autofocus function. When paired with a camera that does not have an autofocus function, it can be used with as a manual focus lens.
*AF-compatible models for SDM, DC, PLM lens drive: K-70/K-1/K-3II/K-3/K-S2/K-S1/K-50/K-30/K-5 II/K-5IIs/K-5/K-01/K-7/K-r/K-x/K-m/K20D/K200D/K10D FW Ver.1.30/K100D Super
Focus Control System
- Power focus
- = The amount of rotation of the distance ring is detected, and the motor in the lens barrel is operated using an electrical signal.
Since there is little backlash, high-precision manual focusing can be done. When the power is off, the focus does not work.

HD Coating to enhance imaging power
After a thorough review of the lens coatings applied to the popular smc PENTAX-FA35mm F2AL, PENTAX applied the latest HD Coating* to this lens.
Compared to conventional multi-layer coatings, this high-performance, multi-layer coating reduces average reflectance and improves light transmittance to deliver extra-clear, high-contrast images free of flare and ghost images, even in demanding lighting conditions such as backlighting.
* HD stands for High Definition

SP Coating to repel stains
Applied to the lens’s front surface, the SP (Super Protect) Coating is highly repellent to water and grease, making it easy to wipe off any stains.
This frees the photographer from worries in outdoor photography.
New exterior design to match latest digital SLR models
While retaining the overall size of the original smc PENTAX-FA35mmF2AL, this lens features a totally new exterior design, similar to that of the latest DA- and D FA-series lenses. This new appearance makes this single-focus lens a perfect partner for latest K-series digital SLR models.
Since this lens retains the aperture ring, it also accommodates many of the functions provided by film-format SLR cameras and older K-mount digital SLR models, making it possible to enjoy photography using a greater range of cameras.
