I have it on my D7100 and I'd say it's on there 90% of the time. Only recently I've been shooting landscapes and astrophotograpy so I go with my wide angle.
As for the performance of a FX lens on a DX body, I think it's been great. It's a solid all around lens. If I find myself needing a little extra speed then I reach for my 35mm prime but that's rare these days.
