Third-party reviews

Based on 1,517 buyer reviews from online shops.
Reviews last updated: July 2026 · How we calculate this

What we like about Pentax SMC DA 35mm F2 4 AL

  • Excellent value for money and highly affordable
  • Superb center sharpness even wide open at f/2.4
  • Extremely compact, lightweight, and portable
  • Good performance in low-light conditions
  • Produces smooth, pleasing background blur (bokeh)
  • Fast and accurate autofocus performance
  • High contrast with minimal flare and distortion

What we don't like about Pentax SMC DA 35mm F2 4 AL

  • Cheap plastic construction, including a plastic lens mount
  • Noisy autofocus operation due to the legacy camera-driven screw system
  • No weather sealing or moisture protection
  • Lacks Pentax's 'Quick-Shift' manual focus override system
  • Noticeable vignetting when used wide open
  • Does not include a lens hood in the box
  • No focus distance scale or markings on the lens barrel
  • Low maximum magnification ratio, making it poor for close-up photography

Verdict

The Pentax SMC DA 35mm f/2.4 AL is a lightweight, 'normal' prime lens designed for APS-C sensors, offering a 53.5mm equivalent focal length. It features a fast f/2.4 maximum aperture, hybrid aspherical lens elements to reduce aberrations, and a Super Protect (SP) coating to repel dust and grease. Its main pros include an incredibly compact 'pancake-lite' design weighing only 124g, impressive sharpness even wide open, and a very affordable price point. However, cons include a plastic mount, the lack of a Quick-Shift focus system, and a noisy, screw-drive autofocus motor.
