A simple task and presented in order of priority:
- 10.5MM f/2.8 DX fisheye - £450
- 300mm f/2.8 VR - £3000
- 105mm f/2.8 VR Macro - £500
- 400mm f/2.8 (but only if they bring out a VR version) - £5500
- 200-400mm f/4 VR - £4000
- 200mm f/2 - £2500
That only leaves out two lenses that I'd like Nikon to design/release:
- AF-S 20mm f/1.4G prime
- AF-S 28-70mm f/2.8G VR
And perhaps, whilst they're at it, update the 50mm and 85mm f/1.4 lenses to AF-S G types too (f/1.2 would be really nice as well

)
So that makes for just under another £16,000 in lenses to pick up over the next few years - excluding anything new that Nikon might put out. Proof positive that you spend more on your lens collection (investments) than you ever will on cameras.
Sometimes I wonder; if someone had told me exactly how much I was likely to spend on cameras and lenses when turning full-time pro, would I have still done it?? I'd probably have laughed and said "Yeah, right... £28K on camera gear for myself... HA!"
