I have a small digital stopwatch with an LED display to countdown my exposures. Advancing to the next frame drops the mirror back down. For exposures of 8 sec or longer, this has no visible impact on the image.Ħ. When time is up, I hold a ball cap or something similar in front of the lens as I slide the switch back to "A". The shutter stays open until you slide the switch back.ĥ. Using cable release, trip the shutter (it's very quiet without the mirror flapping up). Camera on tripod, focused, composed, aperture set. Once you've done it a few times in practice, it's very quick. The set screw just serves to lock the switch on "A" when you are not doing time exposures longer than 8 sec. You turn the set screw on the lens all the way out beforehand, which allows you to slide the T switch without any fiddling. but if it can work for once in a blue moon, I'll work it out. so it's not like it's going to be my main technique or anything. If this is just NOT the right camera to try this. so I've apologized there (and repeat that I apologize for not noticing the exclusion before clogging their bandwidth). Yes, I did post it in the Bronica sub-group, but then I discovered the group was actually and specifically excluding the SQ-A. If you have experience with this operation, I'd appreciate hearing from you. All the while of course you need the camera on a tripod and the mirror locked up. 'cause I can't figure out what I'm really trying to do to/with the set screw thing. 'cause I haven't figured out how to move these slides for the life of me. I may not have the details completely right. If I get it right, you have to find a way to release the unthreaded set screw on the lens so you can move the slide on the "A" ring, press the shutter button, count down the exposure, use a sheet of cardboard or something similar to cover the lens, and then re-shift the slide to close the lens again. Seems like you have to manage like a one-armed paperhanger. By this, I mean is it possible in a practical way? With the Bronica SQ-A I'm curious about the rather fiddly long exposure option.
