stopping down a lens means increasing the f stop which is the opposite of shooting at f2.8 which is a lens aperture wide open. If you stop a lens down you get a greater depth of field and more of the image will be in focus- but when you stop a lens down you are reducing the amount of light entering the lens and therefore reducing the actual sharpness of the ...

Stopping down is suggested because many lenses are considerably less sharp when wide open. This does not change on a crop-camera, since it is a property of the lens. There is however for most lenses a difference between center sharpness and corner sharpness. Most of the time, the center sharpness is substantially better than the corner sharpness.
The ...

The need to "stop down" a lens has to do with the construction of the lens, not the sensor or camera. In any lens, there are tradeoffs, and the most significant tradeoffs come with cost. A cheaper lens will produce poorer quality at a greater number of "wide" apertures than a more expensive lens. This is due to the quality of the optical materials used for ...

Yes, you still need to stop down to achieve best image quality and the sharpness and contrast are properties of the lens (unless the lens is so good it out-resolves the sensor).
However, on APS-C (with a full frame lens) you don't get all the problems related to the corners of the image (mostly corner softness and vignetting) because the sensor only "sees" ...
