I borrowed my girlfriend's La Sardina and this is my first roll with it. Both of us have noticed that generally, the left part of the photos are coming out blurry as compared to the right side of the photos. Thoughts? / This photo was an accident - sometimes the film advance knob doesn't stop when it reaches the next frame and winds up opening the shutter to take a picture (without the button being pressed); it then continues winding until it hits the next frame. This picture was taken while I was winding the camera.
