Not true. You *will* get greater depth of field from the 50mm on the
E-1 vs 100mm on a full-size 35mm frame. That even accounts for a
smaller circle of confusion on the E-1 owing to the need for greater
magnification from the E-1 to produce equal size prints.
Read the details in my earlier post where I have actually done the DOF
calculations.
