Think about it; He can't get closer then a "meter" (39 inches) on 6x6 with an 80mm lens for a head shot. My question is, what kind of head shot does he want to produce, what enlargement size is he going for and how much is he going to loose cropping? I just checked with my Rollei and he should have no problem cropping to 11x14, and maybe larger. A tube will just get him limited DOF and distortion, which he may want, and the reason for his post. Otherwise we all know, a 150 or greater for perspective.
