Super-quiet and fast auto-focus (HSM) makes for a lens larger than most f/1.4s. Slightly sharper by a hair than the others—price is higher, too.
Similar in size, features, and price (though not format) to Sigma's 30mm f/1.4 high-speed "normal" prime for DSLRs with APS-C sensors, this 50mm full-framer ($500, street) also belongs to Sigma's EX family of pro-quality glass. Unusually expensive compared with 50mm f/1.4 glass from Canon, Nikon, Pentax, and Sony (the Pentax streets for $200), the Sigma scales up to an 80mm on most DSLRs, and is available in all popular mounts except Four Thirds.
