For you landscape and architecture photographers out there, Zeiss has just the lens for your wide-angle needs, a Loxia 21mm f/2.8. The new Loxia is designed specifically for Sony's full-frame E-mount so if you're an A7 diehard who has been thirsty for a serious wide-angle lens, there won't be many lenses that can stack up to the quality of Zeiss glass. As with the rest of the Loxia lineup, the lenses are manual focus. No autofocus or automatic apertures, this will require getting your hands dirty to grab that perfect image and for the purists out there, they wouldn't haven't any other way.
Zeiss adds a new wide-angle to its ultra-premium lens line, the Otus 1.4/28
The Rolls-Royce of lenses goes wide.
