Recently, I took out my RZ 67 with the AE Prizm Finder I after it had sat unused in a backpack for several months. Previously it had worked fine, but when I attempted to use it this time, there seems to be something wrong with the electronic interface. Mechanically, the camera works great, but when I put the Finder on it and depress the shutter halfway, instead of a meter reading, all I get is the center red warning light which (according to the manual) means the darkslide is in place even though the darkslide is not in place. It has a new battery. Any thoughts or suggests for what I could do before taking it in for repair? Is it the Finder or the body?
