Sharpness + Noise Issues with 70D

[JohnTrav]

When you frame your shot and focus for the first shot. After it locks focus turn AF off to keep they same focus and that the three or however many shots you take. See if that helps. It's possible that it's refocusing between frames.

If you are letting the camera pic the focus point using AF it might not be focusing on the right part of the frame either.

OP, to find out if your equipment are the issue or not, it is better to do some tests under an control environment. The environment of the photo you post was not an ideal environment for judging if your gears have problem or not.

Do you have access to another body to slap your lens on? If you can, set up a subject in a controlled environment, use manual mode to make everything identical but use AF (same focus point if possible), and see what happens.
