david_love2 Posted May 11, 2008 Share Posted May 11, 2008 I have a 645 Pro (manual everything) and very often use the bulb setting for long night exposures. In this mode, the battery is automatically shut off to save battery life. I am interested in getting a (used) Mamiya 645 AF or AFD. Does anyone know if the bulb setting on these models automatically disable the battery as well, or, do the "automatic" features of these models require the battery to be active. Also, does anyone have an opinion on the Mamiya 1manual focus 105-210mm ULD lens? Thanks, look forward to your replies. Link to comment Share on other sites More sharing options...
reichard Posted May 13, 2008 Share Posted May 13, 2008 Yes, the 'tronics shut down to save battery life. For bulb, you set the on/off/timer to "timer" and then the shutter speed to "B". In this setting, one click of the shutter release opens the shutter, the next closes it. If you have the the on/off/timer set to "on", the shutter will be open only for as long as the shutter release is held in. Link to comment Share on other sites More sharing options...
david_love2 Posted May 14, 2008 Author Share Posted May 14, 2008 Thanks for your info. This is a good feature that I have come to appreciate very much on this camera and am glad to hear that the newer AF and AFD provide the same. I have tried to use my Nikon F80 for long shots at night, but the battery dies quickly, especially on cool nights. Link to comment Share on other sites More sharing options...
reichard Posted May 14, 2008 Share Posted May 14, 2008 I have four rolls of 120 at the local pro shop (still) waiting for the prints. Hopefully my bulb shots came out. Good luck! Link to comment Share on other sites More sharing options...
