so i picked up a mercury 2 for a decent price and then realized that the focus doesn't work (yah duh moment there). The ring that adjusts it wont turn at all. I cant remove the plate on the inside of the back of the camera for some reason it just doesn't want to come out. Any ideas on how to fix? |

saturate the focus mount with lighter fluid. let it soak. it will move again. the lens is removable/interchangeable. you may want to remove it while you work. |

My Mercury II was also very stiff when I got it, and barely moved. The focus thread is pretty simple but seems to be vulnerable to corrosion and sticking. Do the lighter fluid and it should eventually come to life. |

I just did the stuck focus repair on one of my Mercury IIs; I had to use Kroil to loosen it, then cleaned it with lighter fluid and compressed air computer cleaner. I removed the lens first, of course. When I was working on it, the knob on the focusing ring was loose, then popped off. It is only press-riveted in, so I took it to my shop and used a punch to re-rivet it. A simple job, but a part that would be easy to lose in the field. If yours is loose, I would recommend fixing it. |
