Interesting thread. For what it's worth with my 645z set to diffraction control I shoot at the second smallest aperture without worrying about quality loss. At the smallest on most of my lenses I notice a slight tailing of sharpness at 100% viewing. To maximise DOF when using teles I either focus manually on the most obvious subject to the eye or the main bulk of the scene as I see fit and then view on the back of the camera to assess if the DOF extends to the points I want. When using wider angle lenses I'll focus on a pojnt about a third into the scene. I did use the DOF markings on the lenses but found them to be misleading and not producing satisfactory results. I use a FDA25, 35, 55, 75, 150 and 300 A.
