Hi.I'm new in photography. I owe a Rebel T6s (w) two lenses and try it both of them in different settings and pictures come out blurry. Also, I have a problem with controlling camera setting in manual mode with the aperture and shooter speed. Is there a problem with me or equipment. Please help me. Thanks.
