B&H has the 50mm ART available for pre-order!
by phone only, and according to someone on FM the pre-order amount was $950
This lens has so much win written all over it seriously, watch the used 50L price tank and drop below $800 which I still won't buy lol
I don't see any answer from Canikon which can compete with this. All Canon will do is either a 50LII and charges $2k but still won't be as good as the Sigma, or some lame 50 f2 IS for $800.
