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.
