The buzz on the 70D is mostly about the hybrid AF system for video and 'Live View'. And while it uses a whole new 20MP sensor, their older and more common 18MP sensor was not as good as Nikon's (Sony's) 24MP sensor or even the 16MP sensor. Even if it's an improvement over their earlier 18MP sensor, that still doesn't guarantee that it's as good as the D7100's 24MP sensor.

Concentrate on what lenses you want and can afford. Then worry about the body.

Which would be your suggestion: Sigma's 17-70mm f/2.8-4.0 or AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR???

Being "budget & Quality-cost ratio" wise...

The Nikon has more Vignetting, the Sigma has a lot more Chromatic Aberration, the Sigma is very slightly sharper, and they both have about the same amount of distortion. The Sigma is faster, but the Nikon is longer.

If you'll be using this for event photography, the Sigma's CA can adversely affect images because of the higher contrast in formal dress.

The Sigma is about 20% cheaper.

Comparing the Sigma 17-70 to the Canon 15-85, the Canon has a little more vignetting, the Sigma has a little more CA, the Sigma is very slightly sharper, and they both have about the same amount of distortion. The Sigma is faster, but the Canon is longer.

The Sigma is about 30% cheaper.

If you want to use this type of lens, I think you should be looking at Nikon bodies.

Given that most Nikon bodies correct CA, would this be less of an issue with the Sigma...?

The lens correction in Nikon bodies is only good for their own lenses, which is true of most camera manufacturers.
