Well, everything is relative, and to each his/her own. But all of the f2.8 glass is heavier than of slower glass. And in my case, a lot of the time I'm also enjoying the weight savings of the D800 versus the D3s. Together, I save over a pound — which handheld in summer sun for five hours is a lot!
But there's the right tool for the right job. Low light paid shoot is with the f/2.8 glass on the D3s!
