Hi everyone!
I am sorry to say that my lens has stopped working properly. My Sigma 28-200 IF aspherical lens is not functioning properly. The lens has a closed aperture and won't open. Unfortunately, there is no manual aperture setting on this lens. When I take shots, I can hear the aperture trying to open but being blocked by something.
Is there a video of this model being disassembled? Is there a similar model that can be used as a learning resource, or does anyone have a video of this model being disassembled?
Any comment or feedback is valuable, regardless of the response.
have a good one
