: I believe the shortest setting of both the bellows and the TAT are too
: long for the 80mm to focus at infinity. The 80mm is a double Gauss design,
: so its rear nodal point is near the middle of the lens, so you would need
: about 20mm or so of extension. That definitely eliminates the TAT.


I've just tried the manual 80 on an off-brand 20mm tube. It focuses at about
1.5m. With the Oly 14mm tube this lens focuses at infinity (only).
