I have a question about the need for a mid-range zoom. I have a D700 with Nikon 14-24 2.8, 50 1.4, and 70-200 2.8. Last week, a couple of friends who consider themselves "Semi-Pros", whatever that means, kept raving about how much their mid-range zooms were the greatest lenses ever made. I currently don't own a mid-range zoom and don't plan on getting one. I shoot landscapes with the wide-angle zoom and portraits and sports with my tele-zoom. For everything else in between, I use my 50 and reposition myself. Am I really missing out by not having a mid-range zoom?
