Prime lens for Pentax K-mount DSLRs

The Sigma 35mm F1.4 ART DG HSM is a premium prime lens built for Pentax K-mount DSLR cameras. Its fast F1.4 maximum aperture excels in low light and creates shallow depth of field for portraits and street photography. The optical design uses Special Low Dispersion and aspherical elements to minimise aberrations. A ring-type ultrasonic Hyper Sonic Motor provides quick, quiet autofocus with full-time manual override.

Suited for low-light and portrait work.

Photographers who need a wide maximum aperture for indoor events, environmental portraits or creative background blur will benefit from the F1.4 design and 35mm focal length. The 67mm filter thread supports circular polarisers and ND filters for video or long exposures. Shooters who require variable framing or telephoto reach should consider a zoom lens instead, as this prime offers a single fixed focal length.

35mm focal length with 52.5mm APS-C equivalent

On full-frame Pentax DSLRs the lens delivers a classic 35mm perspective, while on APS-C bodies it provides a 52.5mm equivalent field of view. Minimum focus distance is 0.30m (11.81in), allowing close-up detail work. The lens accepts 67mm front filters and stops down to F16 for extended depth of field when needed.

Questions about this item

How does the f/1.4 aperture hold up during long low-light sessions?

The f/1.4 maximum aperture gathers ample light for extended low-light shooting, while the nine-blade diaphragm maintains smooth background blur throughout the session.

Does the Hyper Sonic Motor run hot or loud during all-day video work?

The ring-type ultrasonic HSM operates quietly and stays cool during continuous autofocus, making it suitable for lengthy video recording without audible motor noise.

What Pentax body mount is required for this KAF3 lens to function?

The lens requires a Pentax DSLR with the KAF3 mount; it will not autofocus on older K-mount bodies lacking the KAF3 electrical contacts.
