UPDATE: Price Announced - $850 - Preorder at B&H Photo Video. This is now the cheapest Autofocus capable 24mm f/1.4 on the market.  Shipping: March 20, 2015Sigma has announced a new lens in their excellent ART series. The Sigma 24mm (38mm on crop) f/1.4.  We love our 35mm f/1.4 and 50mm f/1.4 from Sigma and this is likely to be another winner.   Why do we love the Sigma ART series? They are exceptionally sharp, very well made and offer a great value, saving you several hundred over the similar Canon L lenses and offering better sharpness!  Christina quickly sold her 50mm f/1.2 after seeing the review and side by side I did with my Sigma 50mm f/1.4, we now own two of these 50mm f/1.4 lenses and one 35mm f/1.4.24mm is a wonderful walk around focal length and you now have several options at this focal length depending on what brand you use.
