The Asahiflex IIa had no 'IIa' model designation on the body but was just labeled Asahiflex like the other models. This camera came later than the 'IIb' model (which continued to be available), had the instant return mirror and introduced slow shutter speeds which were set through a dial on the front. The IIa retained the secondary eye-level viewfinder.
