I warned you I am a wide-angle nut: I use an 8mm f4 Sigma, 8mm f2.8
Nikkor (both sometimes with TC14A converter), 16mm f3.5N (+ TC14A),
15mm f5.6N, 20mm f2.8N, 28mm f2.8N AIS, 28mm f4N PC, 35mm f2.8N PC,
35mm f1.4N, 28-135mm f4-4.5 Tamron SP, 35-105 f3.5-4.5N. With these,
I haven't missed the 18mm and 24mm's I sold. For my own work, the
20mm and the 16mm (with or without the TC14A) are the favorites,
along with the 35-105mm and 15mm (plus occasional very long lenses).
For travel, I like the 16mm, 20mm, and 35-105mm (or 85mm f2 and TC14A). For commercial people work (including non-wides), the order is: 35mm f1.4 (way up there!), 20mm (up there, too), 85mm f1.4, 80-200mm f2.8AF (with or without the TC14C) (or 70-210 E, and TC14A), 16mm, 28mm, 50mm f1.8, 50mm f1.2, 28-135mm. For architectural work: the 15mm, 28mm PC, 16mm, 8mm (plus TC14A), 85mm, 105mm MF macro. For aerial work: the
105mm f2.8 MF macro, 50mm f1.8 compact, and 35mm f2.8 PC. While I am
at it, my favorite macro rigs: 90mm f2.5 Vivitar Series I + 1:1
adapter + TC14A or TC200 (at marked f11-16) (with or without 6T
achromat, tubes, and TC14C added or substituted); or the 200mm f4 non-macro Nikkor + Sigma achromat + PN-11 or TC14A or TC200 added
(at marked f11-16). O.K., for longer lenses, I like the 80-200 f2.8
with the TC14C, the 300mm f2.8 EDIF Nikkor with or without the TC14C
and TC300, and the older 500mm f8 mirror with and without the TC14.
And, for that desert isle one-lens-only stay: the 20mm f2.8 (at least now - in the past, it has been the 16mm, 15mm, 35mm PC, and 55mm f2.8 [times change ;-]).
Hope this helps.
