My pictures no longer seem to be sharp. I generally use meter to select focus point and use manual settings to click pictures. Since some time i noticed this change. Could this be an issue with my camera or lens? Do i need to change any of them? I got my camera in 2011 and my lens around an year ago.
I am attaching a few sample pictures.
In the following picture, focus is on the tree. Aperture = 1.8. Exp = 1/2500 In the second picture, the focus was on the woman.
