I have a etrsi and am wondering if I can use any of the many flashes available without harming the camera ? I have read so much of how some flashes can fry the circuits of cameras that I'm a little bit leery. I know that on Digital camras you must be very careful but I'm unsure when it comes to older cameras such as my Bronica. Specifically, I have a Vivtar 352 flash I'd like to use with my Bronica. I have this flash so thought why not use it ? I have used it with my Yashicamat's with no harmful effects. thanks in advance for any info.
