Vivitar Flash with FT-1 : LUSENET : Konica 35mm SLRs : One Thread

I have rarely used my FT-1 for flash pictures, relying on my trust Olympus Stylus instead. I have inherited a Vivitar Auto Thyristor SMS20D flash unit and was wondering if anyone had any experience with this or siimilar units. 1. Can I use this with AE? 2. On the back of the flash are 3 selections, M, A1, A2. I am reasonably sure that these settings only impact the informational windows on the flash unit and do not interface with the camera. Is that correct? Any info would be appreciated.

Vivitar Flash


Dedicated flash units have additional contacts, most often in the hot shoe, that pass information to the camera. In the case of the F series Konicas, two additional contacts set the camera to flash mode,and place flash status in the viewfinder. Some Sunpak models have a module that simulates some of this function. With any other flash, you will have to set the shutter to it's X-synch speed (the orange 60 on your FT-1 dial, though 125 works with many flashes, except some auto-thrystor units that quench the light in <1/10,000 sec. You must also set the lens to the appropriate f-stop depending on the flash's mode. I have a Vivitar that gives a choice of four f-stops. If you use the flash in AE mode, the most likely result will be an incorrectle exposed and possibly partly cutoff image.
