New Bronica SQ-AI (to me - last Thursday 2-4-16) and trying out the setting and shutter with blank film back, and using multi exposure mode to set the shutter. I have an AE-Prism Finder -S that has the On-Off switch on the left side and Manual-Auto on the right side. Just found out tonight that if I set it to "Auto" no matter what shutter speed is selected on the dial on the left, it sets the shutter according to the metered light and what the aperture is. But!!! I have had the darndest issue with trying to get a reading on the light meter and setting off the shutter. I try to very lightly touch the shutter and I can sometimes get the reading, IE 60, 125, 250, 30 so on. And other times as I am trying to get the shutter to read, KER-CHUNK the mirror goes up and the shutter releases. Is anyone else having this same issue? Or is mine just a very sensitive shutter release?
