My personal favorite is the Rodenstock 180mm Apo Sironar-S. Nice lens, optimized for a wide reproduction ration (can us it for "macro"), but it isn't the smallest thing around. The Fuji 180A is a nice choice if you backpack or take it on long hikes, but was always flare prone in my experience - so I ended up selling mine and using a 200mm Nikkor M when I wanted a light lens, but I really prefer the 180mm focal length and the Rodenstock is nearly always what I carry.
Depending on your focal length tastes, the 200mm Nikkor M should also be on your short list. BTW, this lens is also rated to cover 5x7, but will illuminate 8x10 evenly at f/22. The corners on 8x10 aren't very good, but I also haven't tried stopped further down. It also seems to do very well at moderately close distances.
Just for hoots and giggles, I also picked up a little 7" uncoated Berlin Dagor that's clear as a bell and covers 8x10 stopped down although the corners my not be quite as sharp as the center. As small as the Fuji 180A. Does a surprisingly good job controlling flare being a 6/2 construction, but I wouldn't recommend it if it's to be your only lens. In that case get the 180mm Apo Sironar-S.
