My lens is blurred both in pictures taken and in its viewfinder when zoomed in. When I look at the viewfinder and I zoom in, the subject at which I am looking at through the viewfinder becomes blurry. Because of that, when I take the picture of it, the photo is blurred. It happened after I've done customization in manual mode (M). I fiddled the shutter speed, ISO and aperture, and now all modes are affected, even those standard modes (landscape, night portrait, flower, sunset, food, etc.). They all get blurred when zoomed in both in viewfinder screen and in final photos taken. Please help me. I appreciate your help. Thank you so much in advance.
