I recently became interested in analog photography. After doing quite a bit of research I decided to borrow a '59 Kiev 4A from my father to try out my photography skills. After a short course on the camera's operation I snapped a few pictures from a moderate distance, then close up - at the lens' smallest 0,9m range. Then when I tried to take a picture at range again I noticed that when trying to focus, the image in the small rangefinder rectangle of the viewfinder doesn't seem to be moving. It only only moves very slightly at 0,9m-0,95m focus, then it stops moving. I tried to be as gentle with the camera as possible since it is quite old (and maybe fragile), but it seems something malfunctioned.
My question is is there a way I could fix this myself or do I have to find a repair shop?
If I manage to get it fixed I might share my first ever pictures taken on film here
