Digital BW, The Print

The focus past infinity seems to be a growing necessity on modern lenses,
probably due to focus shifts at different temperatures.
 
Fortunately most of my legacy lenses work just great on my D3 along with
focus confirmation, which is good for me due to eyesight not being what it
was 20 years ago.
 
But I do miss the aperture and depth of field indicators on modern lenses.

Definitely. 

The auto-focus cameras could be programed to automate much of this. 

I think pro video cameras have pre-set stops at least at the ends (never had
one to play with, however). 

Many AF lenses (e.g., Canon) don't even have an infinity stop where you'd
want it. They need their eye-controlled AF to be linked to a fast dual or
multiple-focus system.
