[Adam Belle] ” Is it also worth renting a 7D for the crop sensor and that little bit extra zoom?”
No, it’s not, because it doesn’t really get you anything. For example, a 200mm lens is a 200mm lens no matter what camera and sensor you are comparing it to. You might think you are getting a tighter zoom with the smaller sensor camera, but that’s only because the sensor is just using a smaller portion of the image projected by the lens. The end result is the same as if you shot everything with the larger-sensor camera and just enlarged the image enough to match the field of view of the smaller one. It’s definitely no reason to wag an extra camera body along.
[Adam Belle] “Will the f4.5 be low enough to shoot hand held at 400mm in less than perfect light with the 7d?”
Probably not. To shoot 400mm handheld you will need a pretty darn high shutter speed or your images will be blurry. So if you force a high shutter speed with a lens that slow in poor lighting, that’s going to require a very high ISO for good exposures, and you are much more likely to get unacceptably grainy/noisy images. I think you’ll at least need a tripod, monopod, sandbag, or other support.
