I\'m putting together an extensive comparison test of primes at the 180mm focal length. I\'ll be measuring actual focal length at various distances, running Imatest, doing Diglloyd-esque A-B comparisons of static subjects (some of which will test resolution, some chromatic aberration) at various apertures, and doing \"field testing.\" If I can figure out how, I\'ll even be testing transmission (finding actual T-stop, vs. claimed F-stop).
I\'ve acquired these lenses (multiple copies of most):
Hasselblad Sonnar 180/4 CF
Leica APO-Telyt-R 180/3.4
Nikon AF Nikkor 180/2.8D ED-IF
Nikon Nikkor 180/2.8 ED AI-s
Sigma APO-Macro 180/2.8 EX DG OS HSM
Tamron SP180/2.5 LD(IF)
Vernon Edonar 180/3.5
Voigtlander APO-Lanthar 180/4 SL
Zeiss Jena DDR Sonnar 180/2.8 MC
What other tests should I do? What other lenses should be included? (Unless FF mirrorless [other than the VG900, which would be an expensive hassle] happens soon, this will be done on a D800E, so Nikon\'s flange distance is a limitation)

I\'m putting together an article with side-by-side comparisons and tests of some 180mm lenses. Hopefully I\'ll be doing this again in the future with other focal lengths.
I have a Nikon 180/2.8 ED AI-s and just acquired a Leica 180/3.4 APO-Telyt-R. I may also pick up a Hasselblad 180/4 Sonnar.
What other lenses should be included? (Unless FF NEX happens pretty soon, this will be done on FF Nikon, so flange distance is a limitation)
Edit: (Probably Final) Line-up Includes:
