Currently I shoot 35mm slide film with a Pentax system. I am considering the Mamiya 7II to add as a system for my travel photography. For day shots I always use a hand held light meter to measure incident light and set the aperture and shutter speed manually. But for night shots such as a city skyline or a lit up street I set the camera on a tripod and use aperture priority. The camera decides the shutter speed and it can often go up to 2 minutes with my Pentax LX set at f/11 or f/16. I was wondering, with the Mamiya 7II, in aperture priority what is the slowest shutter speed the camera can perform? Also, has anyone shot night shots with a Mamiya 7/7II using this technique? Is the metering of this camera in the dark reliable for night shots?
