If you use a Canon 7D in the editorial work, the Society 18-200 mm lens is the best option. I use Nikkor 18-200 mm VR on my D300 around 85% of the time when the fashion shoot, wedding, sporting event or track, the target 24-70 mm f/2.8 and f/2.8 70-200 would my first choice (two of them, not just one or the other)
