Right.... For exteriors, I find 15mm, 20mm, 28mm PC, and 35mm PC
(and sometimes longer lenses) are useful. For interiors, the 15mm,
20mm, and sometimes the 28mm PC are the most useful, with a 16mm
or 8mm fisheye also sometimes used. None of the above are cheap
lenses. Of the lenses listed, the Nikkor versions that I prefer
are: 15mm f5.6 over the f3.5 (lower distortion, and better corner performance), 16mm f3.5 over the f2.8 (better performance at wide
apertures), 20mm f2.8 over all others (better sharpness, though
the original large f3.5 is excellent stopped-down), 28mm f4 PC
over the f3.5 (better shifted sharpness), 35mm f2.8 latest AIS
over all others (better shifted sharpness). An older-style 20mm
may be a good way to start (and I just happen to have one for sale
in nice shape for $250....;-).
Hope This Helps
