It zooms up and down, but when it returns to the initial position, it doesn't reset to zero. For example, I reset it to zero with the lens fully open: Value: 1 (I zoom in to maximum) Value: 660 (I zoom back to the initial point) Value: 87, and each time I repeat the operation, that value increases.
I was asking if there's any way we can fix this, since I'm in Argentina, and the shipping costs are high for sending and receiving it again.
