You ought to put the camera and lens on a solid tripod and try photographing things that have lots of contrast and don't move. It is difficult to assess a possible problem when you are handholding, photographing what the camera could interpret as different subjects. So share some low ISO photos of a high contrast subject, perhaps a neighbor's house, a park shelter, a mailbox, etc. Use a tripod and a wide to moderate aperture. If you don't have a tripod, set the camera on a solid surface and use a self timer.
