Sounds interesting but it is 240 grams heavier than the Sony 85 GMII.
Granted the Sony is more expensive but can anyone seriously see differences between the excellent f/1.4's from Sigma and Sony and the f/1.2's?
Let's do the math...The DOF at 10 feet for an 85mm lens @ f/1.2 is 3.72 inches, for an 85mm lens @ f/1.4 it is 4.44 inches, a difference of 0.72 inches, less than one inch.
