The Exa IIa is a 35 mm SLR camera made by Ihagee in 1963-4.
It is a upgrade of the Exa II and it featured a fixed pentaprism with either a ground glass or split-image in the center of the viewfinder. The film advance was also shortened in the IIa from 180 to 90 degrees.
As in the Exa II, the shutter is a vertical-travel cloth Focal Plane shutter, with speeds from 1/250-1/2 and B. A shutter lock button can be used to keep the shutter open for long exposures in lieu of a cable.
The mirror is not instant return, and only goes down when the shutter is cocked.
Specifications
[1] It is similar to the Exa II, but has the sloped ends to the top housing of later Exas. It has the standard Exacta bayonet lens mount, a fixed pentaprism viewfinder, and lever film advance. It does not have an instant-return mirror. It does not have a hinged back; for loading, the back and base of the camera detach completely. Like many Exacta cameras, authorities recognize sub-types; however, McKeown only identifies a type 1 without strap lugs, and type 2 with them.
