<p>Brad, wait for a minute... there is something here that just doesn't sound right. I've never seen a Canonet with stuck aperture blades (altough I've seen plenty with stuck shutter), and i cannot begin to understand how this could possibly be.</p>
<p>Let's start from the beginning. With the camera in manual mode (that is, with the aperture ring on any value but "A"), turning the ring will visibly close or open the diafragm. Does this happen in your camera? Pressing the shutter and recocking it will not cause the camera to return to full aperture, because this is not a SLR. The diafragm will remain at the set aperture, because this is the normal working mode. Or, are you saying that turning the ring will only close the diafragm, but when turning it in the opposite direction the aperture will remain where it is? In this latter case I'm afraid it is not a matter of a CLA and there is some major damage.</p>
<p>On the other hand, with the camera on "A" cocking the shutter will bring it at full aperture. When the shutter is pressed, the diafragm will close at the aperture as selected by the meter, and will stay there until the shutter is recocked. Does your camera do this, or are you saying that several firing/recocking procedures are needed? If this latter, what is the camera's behaviour in manual mode?</p>
