I can't believe I've started a, "Which lens should I get?" thread. But, I can't seem to decide. I'm about to garner my first pro client, a PR agency. They produce events for entertainment-industry oriented clients. Every photographer I've ever seen on a red carpet typically has an AF-S Nikkor 24-70mm f/2.8G plastered onto his/her primary FX body (and, they all have two FX bodies!). But, lately, I've been seeing more and more of the slower, 24-120mm f/4.0 lens as well. I own zero short FX zooms, since I prefer fast primes instead for all of my personal work--but now, duty calls. Most of the event shooting will be with an on-board SB-800 flash, so speed isn't essential, but I was hoping to expose for the ambient whenever practical to lend as much texture to boring event photos as possible. Since I own a D3s, I suppose I could live with a higher ISO without a problem, and get the 24-120mm f/4.0, instead of the industry-standard 24-70mm f/2.8G. Also, most event shooters don't shoot wide-open (even though I would like to in order to better isolate my subjects), since they often have to shoot groups, so the f/4.0 maximum aperture isn't as much as a handicap as it may appear. Plus, I love VR! Thoughts?
