Lens lock w/o battery? I'm wondering what film based cameras do not use the battery to lock the lense open in bulb mode...mainly canon cameras that would take an FD lense...I've got an ae-1, and I'm pretty sure it does use the battery to lock the lense open...maybe it doesn't..does anyone know? Thanks!! 4/20/2007 8:57:53 AM |

Since you have an AE-1, find out on your own. Keep the shutter open by locking the cable release and take out the battery.

Canon A-series and T-series bodies have electronically controlled shutters. The F-series bodies (F-1 and older Ftb) have mechanical shutter systems and the battery powers the meter only.

wrt "lock the lens open", the lens aperture defaults to wide open. To stop down to a particular aperture, all the F-, A-, and T- series bodies that take FL/FD mount lenses use a fully mechanical linkage for operating the aperture during the exposure. There is no battery drain from that.

Hi Olen, I think you mean lock the shutter open, right? I just took a test with my AT-1. When I took out the battery in bulb mode, the shutter closed and the lens returned to its widest aperture. But I think Jon is right that the lens opening will not drain the battery. 4/21/2007 6:26:23 AM |

Minolta's older SR series cameras work mechanically without the battery. Like the sr-T101 which is completely functional sans battery. The only power dependant feature is the needle meter in the pentaprism. I have one and use it without the battery and make some wonderful images and will continue to do so for years to come. I hope.

yeah, sorry, I meant lock the shutter open...just wondering, cause the batteries are like 9 dollars...and I don't want to have the shutter suddenly close when I do long exposures or night shots or whatever.
