I think 7D has focus problem by design
No, it does not. It's capable of fantastically sharp images, used properly.
Husain, this nonsense has been bounced around the internet since the camera was released more than three years ago - do we really have to go over it all, all over again?
Maybe yours needs AFMA; maybe yours has a fault; maybe you need to understand that by definition, densely-packed, small-pixel sensors may need a different sharpening approach; and maybe your approach to evaluating sharpness is flawed.
But the 7D does not have a "focus problem" - it wouldn't be the world's most popular APS-C sport/wildlife camera if it couldn't focus and couldn't produce amazing sharpness.
