I don't know, that is why I am asking about shutter speed. I think of the GA645 as a 35mm lens camera, so tend to shoot with slow shutter speeds. However, the lens is in reality a 65mm one so I might be over doing it with my slowness. Here are a few examples. The monochrome image has light leak as the roll did not wind properly for some reason. But you can see that nothing is in focus. I dont have the shutter speeds used for these in front of me right now.
