Best camera for the sigma 17 40mm f 1 8 dc art?

The Sigma 17-40mm f/1.8 DC Art is made for APS-C, so I'd pair it with an APS-C body and get its full field of view at full resolution. My picks:

You can also fit it to a full-frame body in crop mode, but you'll be throwing away resolution, so I'd only do that if you already own one. For more on sensor sizes, see Sensor sizes.
