Set the camera to aperture priority with (say) a 50/1.8 lens set to f/2.8, then activate the DoF preview -- and through the viewfinder you'll see no change at all in most cases. | |

All DSLRs have a focusing screen — just not usually optimized for manual focus

Lens with the maximum aperture opening of f/1.4 will allow you to see more than the lens with the max aperture of f/2.8. Since the lens stays wide open while you’re focusing, and until you press the shutter. | |
