Isn't it 65mm plus the depth of the body? I didn't think about that, so
maybe the 80mm won't focus to infinity on the auto-tele-tube. And the
bellows fully collapsed seems to be 40-50mm deep, so added to the body depth
maybe that wouldn't work either. Olympus only says the 135mm works to
infinity (but for distance shots I'll use my 135/2.8 instead!)
