I don't think I've ever looked forward to getting a lens so much in my life, and yes that includes my tilt-shift lens'. This Sigma 50mm 1.4 Art lens is comparable (and even better in some areas) to the Zeiss’s 55mm f/1.4 Otus. Only 1/4 of the price at about $1000! With a bit of luck, I'll be shooting with it this weekend!! Check out the awesome review at GIZMODO (image sigmaphoto.com)
