I don’t generally purchase or condone the purchase of third party lenses, but if you’ve got one of those fancy new 4/3 system digital cameras and you’re looking for a prime portrait lens then Sigma may have something for you. The 50mm f1.4 EX DG HSM has an aspherical lens, nine rounded blades and promises fast and quiet AF. Sigma is mum on the price, but the regular equivalent of this lens goes for $730.
