Pentax me super shutter won't open. won't wind, wont take a picture :(
Have you not used it in a while?
This could be one of two issues:
One, it could be the battteries. The ME super is not a fully mechanical camera like the mx, if the batteries are depleted then the shutter sticks open as it does not know how long to stay open. Turning the selection wheel to 125X usually unsticks it.
Two, the lubricant that pentax used in the 70's and 80's has a very bad tendecy to polymerise and turn sticky and solid. This turns the camera inoperable. Pentax repair service routinely provide cleaning for affected cameras.
Hope this helps, its a great camera
