SX-70 with external flash not synching

Messagepar Lie34 » sam. 13 avril 2024 / 23:22 pm

Hi all,

On my polaroid sx-70 (Alpha model), i would like to add some external electronic flash. (Fuji EF X20). I bought the Realfilmreel Flash adapter , but the images come out black with the flash on.
As if not synching togheter?

An one knows what to do. Is this normal and is there a way out?

As I remember, the speed of the flash musn't be too fast.
Electronic flashes are often too fast as opposed to the original (and chemical) flash cubes flashbars.
That way, the shutter finishes opening when the flash is already off.

If possible, set it to 1/60s or less.

As far as I know the SX70 sets a slow speed of ~1/40 automatically as soon as you insert a flash bar or a flash adapter. The aperture is then set according to the distance setting. So electronic flash should work fine, as it does with plenty of Polaroid and non-Polaroid electronic flashes.

There are adapters for Sonar models, which are different and not compatible with the ordinary SX70, but these should not fit into an ordinary SX70. So maybe the adapter used does not trigger the flash mode correctly...
