Sigma 50mm f/2.8 EX DG Macro - Pentax K
Sigma 50mm f/2.8 EX DG Macro is a Pentax K-mount macro lens with 1:1 reproduction and autofocus. This compact 50mm macro was designed for full-frame use, so it also works well on APS-C bodies where it behaves like a short telephoto, making it useful for close-up work, product photography, copy work and general-purpose detail shooting. The EX-series build is solid for its class, with a straightforward extending barrel during focusing and a classic Sigma finish that feels more substantial than many kit lenses. Optical performance is typically strongest stopped down a little, where sharpness and flat-field rendering suit macro subjects, while the f/2.8 aperture gives a reasonably bright view and modest subject isolation at closer distances. It is not stabilised and is not weather sealed, so careful handholding and sensible storage matter. On the used market, check that autofocus runs smoothly, the focus ring turns cleanly across the full macro range, and the front and rear elements are free from haze, fungus, scratches or separation; also inspect the mount for wear and any signs of impact or excessive dust inside the barrel.
