I mounted the 244t into my AE-1, set the shutterspeed at 1/60 and turned the flash on. The red ready light of the flash turned on, and when i pressed the exposure preview switch on the AE-1, the flash blinked a rapid flash which is supposed to set the aperture and shutterspeed automatically according to the distance of the subject, at least on T-50. According to this, i believe that 244t is compatible to AE-1 and its automations should work.
