Apeture settings

I noticed that different lens manufacturers disagree on depth of field for lenses of the same focal length and aperture. Not surprising because depth of field refers to the observers tolerance for blur. I think Leica tables are more conservative than most and for a belt and suspenders approach I would close down one more stop than they recommend. However camera shake comes into play as well and I try never to use longer than 1/200 sec The old Olympus Trip 35 produced consistently sharp pictures because it had a fixed 1/200 shutter speed (when not on flash).

We all want full frame sensors, or maybe an 8x10 Deardorff, but one trick for getting more DOF is to go to a smaller sensor camera. I've shot some stuff using an old Panasonic FZ-20 that would have been impossible with even a DX sensor.
