SKU CH-T190-5YZK9

  • Product typeAccessory
  • Shallow depth of field with F1.4 aperture
  • SP coating repels water and grease
  • Eight-blade diaphragm creates soft bokeh to F2.8
  • 50mm standard on full-frame, 76.5mm on APS-C
  • HD coating reduces flare and ghosting

Standard and medium-telephoto focal lengths

The Pentax FA 50mm F1.4 HD Coating Lens mounts on K-mount digital SLR and film AF SLR bodies. On full-frame cameras it works as a 50mm standard lens. On APS-C cameras the field of view matches a 76.5mm medium-telephoto lens. This single optic covers both perspectives without a crop penalty.

K-mount fit and front-element coating

The lens uses the legacy K-mount so it attaches directly to compatible Pentax bodies without an adapter. A Super Protect coating on the front glass repels water and grease, making smudges and droplets easier to wipe away during everyday handling.

Bright aperture and eight-blade diaphragm

The maximum F1.4 aperture gathers ample light for low-light shooting and creates a very shallow depth of field. An eight-blade diaphragm produces soft, natural bokeh from wide open to F2.8 and reduces streaking from point light sources. The HD multi-layer coating cuts flare and ghosting in backlit scenes.

Questions about this item

What maximum aperture does the HD Pentax-FA 50mm F1.4 lens offer, and what depth-of-field effect does it enable?

The lens opens to F1.4, producing a very shallow depth of field for strong subject isolation and soft background rendering.

Which camera mount does this lens use, and which Pentax bodies will it fit?

It uses the Pentax K-mount, fitting both full-frame and APS-C digital SLRs as well as film-format AF SLR cameras.

How is the lens attached, and what common mistake should be avoided during mounting?

Align the red dot on the lens barrel with the red dot on the camera mount, then twist clockwise until it clicks; forcing it without alignment can damage the bayonet pins.
