With the only exception of the 500mm f/4.0 (and the new lens kit announcement) Sony didn’t show new Alpha Mount lenses at the CP+ show. Don’t worry new lenses will be announced along the A77! Meanwhile Sigma announced four new interesting lenses at the Cp+ show in Yokohama. Sadly Sigma has not specified when and for which mount the lenses will be released.
A good news: Sigma Japan also announced that the 85mm f/1.4 for Sony will be available on February 11th. You can preorder the lens at Adorama. That’s a good quality and cheaper alternative of the Zeiss 85mm f/1.4 (Click here to check price at Amazon) lens.
