Should you decide to go down the Nikon path (which I would wholeheartedly recommend) the range from 14mm to 200mm could be covered using these premium lenses:
-
AF-S 14-24mm f/2.8 (truly excellent, probably best ultra-wide zoom around)
- alternatively the older, cheaper but almost as excellent
AF-S 17-35mm f/2.8
-
AF-S 24-70mm f/2.8 (haven't tried this myself but reportedly excellent)
- inside the zoom range of the above there are also the faster
AF-S 24mm f/1.4,
35mm f/1.4 and
50mm f/1.4 primes if you prefer
-
AF-S 85mm f/1.4 (brilliant, super bokeh, a classic)
- alternatively the
AF-S 85mm f/1.8 (at least as sharp, much cheaper)
-
AF-S 105mm f/2.8 Micro VR (brilliant allrounder, not just macro)
- alternatively the older
AF 105mm f/2 DC (perfect portrait lens, bokeh control ring)
- alternatively the
AF 135mm f/2 DC (same as above, a bit longer)
- and finally the
AF-S 200mm f/2 VR (beyond reproach, expensive)
- alternatively the older and much cheaper
AF 180mm f/2.8 D (practically unchanged since 1986, one of the sharpest Nikon primes ever)
- if you prefer a zoom for the tele end, the
AF-S 70-200mm f/2.8 VR (which I don't own but which is extremely popular)
