has anyone had a problem with camera shake on the mamiya's. I hired one the other week and when I got my shots back they looked a little soft, not the pin sharp I was expecting. I was using an 80mm lens i think. In hindsight the camera made a huge clunk everytime i took a shot which for the size of the camera I thought may of been normal, but now I'm not so sure. My focus on the subject was fine and it was mounted on a heavy manfrotto tripod. The fact it was hired may of had something to do with it.......
ta for your input,
