OK - DOF preview is not perfect but it is a LOT easier than having DOF tables for 
every focal length you have, especially with zooms. Where would you get them? Where 
would you put them? Another bag to carry?
Perhaps you should review your technique? DOF preview makes the viewfinder dark so you 
have to look it a bit longer so that the eye can adjust to it.
DOF preview is not absolutely necessary, I have many cameras that do not have it but 
are excellent picture takers, like Pentax ME, Leica M6 and Rolleiflex 3.5F (which has 
the best DOF indicator IMO).
All the best!
