OK, I sold my D70 18-70 (didn't find the range extremely pleasing with the variable aperture; 24-120 (sold to upgrade to the 18-200 VR II); 24 f/2.8 (not a great match for digital); 50 f/1.4 (too noisy) and Sigma 30 f/1.4 (backfocus) (Grand total $2100). I retained my 70-200 VR; sb-800 and TC 14IIE. I have on order a D200 and another Sigma 30 f/1.4. I can either afford to buy the sigma and the 18-200 VR II or cancel the sigma, forget the 18-200 VR and get the 17-55 only. I don't shoot wide angle so the 17-30 range is a luxury for me, but I do shoot low light. Can I afford to give up the two stops and the versatility of the zoom? Or am I just lusting after the 17-55? Which option would you choose and why. Option A 18-200 VR II and sigma 30 f/1.4 or Option B 17-55.
