Some Help Please

Your second shot is at 1/100s shutter, which is too slow for a crop camera and a 135mm focal length. The issue on that one is almost definitely blur from camera shake (and possibly subject motion blur too).

The first and third shots are at 1/200s, which is the bare minimum for that set-up. 1/320 would be better. But I think your issue is actually a focus problem. What AF setting did you use? Center AF or did the camera automatically select the AF point? If the latter, that would explain why some of the girls to the side are sharper than the speaker in the middle. Or it could be a combination of camera shake and the wrong AF point.

AF was set to single and I was using the center point. Given the fact that the camera was already opened as far as it would go I guess I would have had to increase ISO? I was concerned about noise.
