Depth of Field

In EOSpedia it was stated that all you need to remember is that a large aperture decreases depth of field, while small aperture increases it. True, but the second thing to remember is the effect of focal length on depth of field.

Absolutely….
there are many articles within photo publications that don’t talk about all factors…I think we have to assume that no other factors are changed.

Absolutely, I've had better depth of field from longer focal lengths than I do with my 50mm f1.8

And the third thing to remember is that DoF increases with subject distance...

I seem to remember reading that subject distance is the factor which has the most marked effect on DOF.

Certainly does, Nigel.
