It could be that with the speed cam off, the shutter is going into T mode. That seems consistent with what you are seeing, and might be perfectly normal for this shutter. Here is how to fix the focus. Do this when the camera is back together except for the front element. In daylight, set the camera on a tripod pointed at something practically infinity (like a few hundred metres) away. Lock the shutter open with the T setting, open the back, and stick a piece of magic transparent tape across the film guide rails so it's taut and at the film plane. That will be your groundglass for focus testing. Now to screw on your front element. I will assume that you have not removed the housing with the focus scale from the element and that your camera was properly calibrated to begin with. Screw the front element on, making note of how it is orientated when it first engages with the threads (i.e. cannot be pulled straight off). There might be only one point at which this can occur, or there might be 2 or 3 separate screw tracks. Screw it in, watching the image projected on the clear tape (it helps to use a magnifier) until faraway objects appear in focus. Now look at the lens -- is the scale at or near the infinity position? If so, you've successfully screwed it in the way it was before, just screw the stop post back in and have a beer. If not, note how the focus scale is oriented. If for example it is about 180 degrees from the infinity focus, then you know you have to unscrew and try again starting about 180 from where you did this time. Repeat as necessary. Remove tape, have beer. August |
