You guys make my head spin. I keep trying to get into these kinds of situational outfits, but when I try it, I always end up wishing I just had my general, chosen gear instead. No matter how I want to justify other lenses, the Sigma 18-35 f/1.8 always ends up being the best choice for general, walking around use. It's really big and freaking heavy, but no lens matches it for function, versatility and how I tend to shoot. The fact is, even though I'm startled by how heavy it is every time I pick it up, once I start walking around, it stops feeling heavy. Once I start shooting with it, I'm glad I decided to go with it.
That doesn't mean it replaces specialized lenses, like an 85mm f/1.8 Nikon, 50-150 f/2.8 Sigma and macros when they're needed, but I can't imagine being glad I took a fixed, pancake lens in place of it.
Currently I'm tempted by the new Tokina 11-20 f/2.8, which would completely round out the whole lens system. I have a (original version) Tokina 12-24 f/4 that's passable, but has less than thrilling image quality. It was perfectly fine on the D200 but it really doesn't measure up with the D7100.
