If we only want to compare the relative DOF when moving a specific lens between imagers of different sizes, both FOV and and DOF can be computed by multiplying with the crop factor. For instance, if we use a 50 mm lens at f/2.0 at a full frame camera, and then move that lens to a 1.6x crop camera and set aperture to f/2.0, the result will as if we've used a 80 mm lens at f/3.2 at a full frame camera in terms of FOV and DOF. But not in terms of speed, the f-stop would still be f/2.0.
1. I'm sure that Sony want their cameras to be known as SonyNow Sony is running the Minolta Konica venture... I think it would be smart to re-release the Minolta name in the future especially considering Minolta had been around for 78 years.
