Ultra-compact 35mm f/2 wide-angle prime for Pentax K mount with superb SMC optics.
The Pentax SMC Pentax-M 35mm f/2 is a compact wide-angle prime lens for the Pentax K mount system. The M-series designation indicates the ultra-compact design philosophy that made Pentax lenses some of the smallest and lightest of their generation, perfectly complementing the diminutive ME and MX camera bodies.
Optical performance is excellent with the Super Multi Coating delivering outstanding contrast and flare resistance. At f/2 the lens provides a useful speed advantage over f/2.8 alternatives for low-light shooting and selective focus. Stopped down to f/5.6 and beyond, sharpness across the frame is genuinely impressive.
The compact dimensions are remarkable — this lens barely extends beyond the camera body, creating one of the most portable wide-angle setups possible. Build quality is typical Pentax M-series with a smooth metal focus ring, positive aperture click stops, and a solid feel that belies its featherweight construction.
Highly sought after among Pentax K mount users and adapted mirrorless shooters, the SMC 35mm f/2 offers outstanding wide-angle performance in a tiny package. On the used market it commands premium prices for an M-series lens, reflecting its combination of speed, compactness, and excellent optical quality.
