I want to expand my workflow to large format camera and lenses with my IQ160. At the moment I use Phase One DF body with 80mm LS and 120mm macro lenses - that is all I need for studio still life and product (rarely wide angle).
I though that logical choice would be Schneider 120mm f/5.6 Apo Digitar M Lens or Rodenstock similar macro lens. And my experience with large format is none.
Reading at this forums and lens specs I found out that this lens for digital backs is designed to be used wide open at f/5.6 (but you can stop down to f/8 at 1:1, and to f/11 at distances further than 1:2).
So, how can I get usable DOF for product photography when everything needs to be sharp? Is focus stacking a must here, which I hate, that shallow DOF would need like 20 exposures? I know that camera movements solve this problem in some applications, but there are numerous objects that just don't benefit from camera movements (like rounded objects, square ones etc), and at 5.6 even these movements won't help.
Is the difference in sharpness so obvious when stopped down to, at least, f16?
So, what's the workflow for large formats digital lenses for extended DOF in studio applications?
