" We’re told the next Art series lens from Sigma will be an 85mm f/1.4 DG HSM Art. However, it’s not coming any time soon. There’s still a small possibility that a new 135mm Art series lens will arrive first, but Sigma feels there will be a higher sales volume likelihood with the 85mm focal length, and will do their best to get it to market first. A new 24-70 f/2.8 OS DG HSM Art is also a possibility, as the chance of an f /2 version has diminished due to costs of development and production. One of Sigma’s biggest marketing strategies is a significantly lower price than the Canon or Nikon version of a lens. That just wouldn’t be possible with an f/2 wide angle zoom for a full frame camera. One example of a lens that hasn’t done well because it wasn’t cheaper than the comparative Canon has been the possibly discontinued 24-105mm f/4 DG OS Art. Yes it would be a stop faster, but would people spend more on a Sigma lens that is a stop faster than the Canon of equal focal length? A stabilized f/2.8 Art version could probably be made for far less money and would carry much less risk for Sigma." " http://www.canonrumors.com/2015/02/sigma-85mm-f1-4-art-lens-nex

感觉之前都是适马自己放出去的rumor, 其实根本没有做F2 zoom的技术 不然如果是市面唯一的f2 zoom + OS 就算价格高一点 也不会超过原厂的24-70 而之前的失败作24-105已经体现出了适马再zoom方面根本还不足以和原厂分羹
