The Zeiss Ikon SW is the 35mm precision camera for uncompromising superwide photographers. Its lens mount takes any lens with M bayonet, in particular the Zeiss high performance superwide-angle lenses Distagon T* 2.8/15mm ZM and the Biogon T* types from the Zeiss ZM range. An accessory shoe directly above the lens takes the corresponding superwide Viewfinder. A second shoe is built in to take a flash, a bubble level or other accessory. The electronically controlled metal focal plane shutter offers speeds ranging from 1/2000 sec. - 8 sec. in automatic mode (AE-lock is available) and 1/2000 - 1 sec. + B in manual mode. Fastest flash synchro speed of the Zeiss Ikon SW camera is 1/125 sec.
