Here are some spyshots about the upcoming Zeiss/Sony Vario-Sonnar 24-70 f/2.8 SSM (SSM = USM in Canon-speak), timed to arrive when they would be introducing their FF camera (A900) next month.
Rumors have it that there is either a Zeiss Vario-Sonnar 16-35 f/2.8 SSM or a Vario-Sonnar 14-24 f/2.8 SSM, along with a Zeiss 70-200 f/2.8 SSM Vario-Sonnar also to be introduced during early 2008. A couple of Zeiss primes (wide) will supplement the current Zeiss Planar 85mm f/1.4 and the Zeiss Sonnar 135mm f/1.8 in their range.
This should roil the waters a bit in the dSLR landscape, since these lenses (being a Zeiss with full metal body and even the lens hood being Aluminium) are supposed to have mindblowing performance, corner to corner.
