(For a particular value of 'good')


With some exceptions most people who buy reflex's relegate them to a
shelf at some point after the initial blush of pleasure wears off. They
are usually (always?) manual focus too ... which can be a challenge for
the wearier eyes out there.


Some cameras, at least my Nikons, have some type of in focus indicators
available in the viewfinder.




That said, with today's low noise sensors, f/8 is not the barrier to
some photography that it used to be. (Shooting in the woods, for example).
