Depth of Field
Todays automated cameras are nice, even with top of the line cameras for the most part you just point and shoot and the camera does the work of determining the exposure and focus. But that leads to one thing I really miss, and that is being able to select depth of focus. Smaller aperture, more of the depth is in focus, large aperture a more limited range of focus. And depth of field preview does not exist. Younger photographers using older camera seem to have no idea what depth of field preview is or how to use it. Stop the lens down on the above image and everything would be in focus.
