<p>Argus/Cosina STL10001 was my first SLR. I loved it and have many good memories of using it. When a spring in shutter mechanism broke I had to move on but repaired it and would still use if I could get the light meter to work well. Not having the correct battery available any more means the meter was off. I have used hearing aid batteries which worked but did not last long. Best wishes for fun times with your Argus/Cosina. I had a little device that came with the camera that slides on the eyepiece and gives a shoe no connections so not a hot shoe.</p>
