This rumor makes no sense. There is already an e-mount 24 Zeiss 1.8. It's a wonderful lens. Sigma's president says they try to do something that hasn't already been done. I would just like them to adapt the existing Art lenses to the E and FE mounts. The lack of fast lenses keeps these cameras from being able to compete with their dslr peers. The 18-35 f 1.8 would be awesome on the emount cameras; and the 35 and 50 1.4 lenses could potentially give the A 7r the low light capability and image quality to go head to head with the Nikon D810. Hope Hope.
