Hello friends! I have a Canon T1i and the lens that comes from the factory is having a failure, when I shoot the photo in the viewfinder it tells me that it is focused but it is not, I already checked the auto focus function and it is selected, what do I do in this case ? Is there a way to solve it at home or is it my turn to buy a new lens?
I suggest mounting another lens to determine if it's the lens or the camera causing the problem.
And of course other way round, too: Mounting the lens onto another camera.
