Sigma 18-250 Macro HSM for Canon
I am using it with camera on a tripod, OS is off, and auto focus is on. When I take the picture and switch into preview mode, I can hear that something clicks in the lens. If I look through the view finder during this click, I can see that the whole view shifts down at that time. If I half press shutter button while still looking through the view finder, I can see that view shifts back.
Why does this happen?
Is there a way to stop this from happening?
