Lens Description: Sigma\'s 50mm f/1.4 EX DG HSM is high quality, professional optics and you’ll know it the minute you pick it up. In the past few years, camera manufacturers have overlooked the need for a reasonable fast prime lens that is compact enough for everyday use, yet provides the necessary image quality to meet the highest expectations. Now, with the advent of the APS-C cameras, the long popular 50mm focal length takes on double duty as a portrait length lens of approximately 75mm on most of the small chip cameras.

Photography Life Review Summary: Don’t waste your money on this lens – it is simply not worth the $500 Sigma is asking for. When compared to other 50mm lenses currently available on the market, the Sigma 50mm f/1.4 has the worst price-performance ratio. Even the much cheaper and lighter Nikon 50mm f/1.8G performs better in most tests in comparison. Read the full Sigma 50mm f/1.4 EX DG HSM Review by Photography Life.
