Often called the mysterious Canon, the II AX was named 'Flash-dedicated Camera' during its development. It was a II A with 1/40 sec. X-sync and a side flash rail with built-in flash sync contacts. Shutter speeds slower than 1/8 sec. were not provided. The slow shutter speed dial hole was covered by a round patch like the II A. Altogether only about 20 II AX and II AF cameras were made.
