Hi at all,
I ran into an unsusal problem while shooting some vertical images. It seems like the shutter moves to slow (mechanical shutter mode) and leaves a regular trace accross the images. On the right side, two of these lines are visible, on the left side there is one more at the bottom. In the middle (for me) it is not percievable.
Interestingly, they don't appear in all images, only where I cover the ground, which is lit by some tungsten lamps.
So, might the sensor already expose before the shutter fully opened? Anybody had this problem before or knows a solution?
