In the Nikon line, a 15mm plus a 20-35, or a 15, 20, 35 set of primes
would work (expensively!), but there is no single lens in any line that
would cover the whole range... If you can accept a considerable drop
in lens quality, there are aftermarket lenses (claiming) 18/19-X
zoom ranges... For a very wide single lens of very high quality and
not unreasonable price, I would recommend the Nikkor AIS 20mm f2.8
or a used AI 16mm f3.5 fisheye.
Hope This Helps
