Pentax 50mm f/1.4 overview

  • 1Description

The FA 50mm f/1.4 SDM AW Lens from Pentax, part of the company's Star Series of lenses, is a standard length prime lens with a bright maximum aperture that enables accurate low-light shooting as well as providing a wide range of depth of field control. While designed for full-frame Pentax K-mount cameras, the lens can be used on APS-C format cameras where it provides a 76.5mm focal length.

Aero Bright Coating II and HD Coating on the 15 lens elements reduces flare and ghosting even when shooting in harsh lighting, and a front element SP Coating repels water and fingerprints from affecting the front of your lens. Autofocus is powered by Pentax's Ultrasonic Motor SDM, providing fast and accurate focus while shooting. Additionally, the rounded 9-blade diaphragm produces smooth bokeh for portraits or other types of shots. This lens is also weather sealed, ensuring consistent performance during adverse outdoor shooting conditions.

  • Ultrasonic Motor SDM enables smooth and speedy autofocus 
  • Aero Bright Coating combined with HD Coating on lens elements reduces ghosting and flare in extreme lighting situations
  • SP Coating on the front lens element repels water and grease
  • Weather-resistant design enables consistent performance during adverse outdoor conditions
  • Rounded, 9-blade diaphragm creates smooth and creamy bokeh

    Pentax 50mm f/1.4 reviews

    HD FA 50mm f/1.4 SDM AW Lens is rated 5.0 out of 5 by 4.
    Rated 5 out of 5 by from Wow Why pay this amount when if you had a C or N they would charge 50%. Sigma do but this Pentax is a classic. I bought it because my favourite lens is my 300DA*. One touch in the store and I was sold. I am super happy with my 24-70 but this HD 50 is so tack sharp you also need another graphics card to keep up. Beautiful build and proper all weather to go with my K1. F1.4 will make me think about focus accuracy (as per the film days. Quality incomparable with the old FA50 1.4 which was soft until f5.6 and then mediocre this hit the nail from 1.4. Back to grass roots normal aspect photography making you plan and frame your image. Remember that only can that the shot once.

    Rated 5 out of 5 by from Pentax pulls out all the stops!! This lens is absolutely hits it out the park in just about every way. Well balanced with a full frame K-1, stunningly sharp wide open and top notch at 2.0, with fast, confident autofocus. Couldn't be happier. One of those lenses that will make you smile with the results. Worth every penny.

    Rated 5 out of 5 by from Most performant lens I've ever used Sharper than the Sigma Art corner to corner. First ring type AF motor in a Pentax lens: we've finally entered the 21st century. Going from all manual lenses, my possibilities feel endless. Have shot one bridal shower and it's the amount of keepers I got was 4-5x as much as usual.This lens should have easily cost $1500 and I wonder how they're even making money on this 15 glass element monster at this price point.
