35mm F1.4 DG HSM Art Lens

This SIGMA prime lens delivers a 35mm focal length with a bright F1.4 maximum aperture for full-frame and APS-C Pentax cameras. A ring-type ultrasonic Hyper Sonic Motor provides quiet, high-speed autofocus with full-time manual override. The optical design incorporates SLD and FLD glass elements to correct axial and chromatic aberration. A floating internal focusing system maintains performance at close distances down to 0.30m.

Photographers wanting wide aperture prime

Suited to photographers who need a fast 35mm prime for low-light work, environmental portraits or street scenes on Pentax K-mount bodies. The 67mm filter thread accepts standard screw-in filters for creative control. Not for photographers who require zoom versatility, image stabilisation, weather sealing or autofocus compatibility with camera bodies that lack an in-body focus motor.

F1.4 maximum aperture decides low-light fit

The F1.4 maximum aperture is the single specification that determines whether this lens meets your exposure and depth-of-field needs. At 1.4 it gathers significantly more light than slower primes or zooms, enabling faster shutter speeds and shallower subject isolation. If your shooting demands a wider maximum aperture or a different focal length, this is not the right part.
