To avoid any vibration affecting the shot, a lens cap can be carefully put on, or something opaque can be held over the front of the lens while moving the switch back to A.
The range on the shutter dial goes to 8 seconds, but there is a B (bulb) setting on the ETRSi only. The only way to manually take exposures beyond 8 seconds on the older models is to use the A/T switch. The B setting on the ETRSi uses battery power the whole time the shutter is open, so Bronica recommends not using B for more than 1 minute.
Thankyou lxdude for your kind response, so just to clarify, I switch to T then use my cable release to open shutter, place cap over lens whilst resetting tab back to A, (closes blades). Also does the ETRS use battery power for leaving the shutter open for long exposures?

Thanks again.
