A new Sigma 24mm f/1.4 Art lens is rumored to be released in October 2014. The new lens will most likely be announced at Photokina in September. The price of the 24mm f/1.4 is expected to be higher than the current 50mm ($949) and 35mm ($899) Art versions. Still no information on a possible 135mm f/1.8 Art model that was rumored a while back.
