If you want super-sharp images then stick with primes. I notice you have a 50mm F/1.4, this lens is going to give you the sharpest images at the expense of flexibility of focal length of course.

Yes, but that's assuming perfect focus. Even being slightly off with your focussing will remove any sharpness advantage a superior lense will give you over a crappy lense.

I trust my AF far more than my eyes when using a matte focus screen. With a proper split-prism focus screen it's a different story, but otherwise you're probably better off sticking to used-defined AF points (none of this auto-AF-point nonsense).
