我部機係裂像對焦+定焦鏡 唔知點樣較好個焦距
有時會影到成張相都矇晒
I took off the bottom plate, looked around for something that looked like the pin mentioned earlier, and guessed right at which thing it was. I moved it so that the winder would move freely, and wound 4-5x, and the stuck mirror came back down. I moved the pin back and fired the camera a bunch of times; looks good.
