They're really quite different focal lengths. At 8 ft, the GH2/20mm combo gives a field of view 7' 2" across, whereas with the K-r/35mm it's almost a foot off of each side, at 5' 6". That's a difference of almost a third.
You're right, and thanks for the correction. With the GH2/20mm you'd have to stand at 6 ft to get the same magnification. At 6 ft the GH2/20mm gives 1.4 ft DOF.
So the DOF difference between these two kits turns out to be negligible.
A Fuji X100 user would stand at 5 ft and get 1.25 ft DOF with the 23mm f/2 lens.
A DA 40mm/2.8 user would stand at 9 ft and get 1.8 ft DOF.
They all seem to be shooting for the same size hole, from different distances, using different clubs
