Sony A850 and flash trigger
I have a Sony A850 and want to trigger my Sony HVL 43AM flash off camera.
I do not want to use a TTL cable or the Sony HVL 20AM flash to optically trigger the HVL 43AM flash.
I do not want use a radio trigger.
I am looking for just an alpha shoe mount flash that will have the only function to optically trigger the off camera HVL 43 AM.
