As daugirdas says, the 24-105 gets wide on full frame.
I have a 7D but if someone was going to buy me a camera it would be a 5DII which will probably be my next purchase anyway
Can we be abit careful in whats being said in this thread.
The 24-105mm f4 on a full frame camera is the same as a 24-105mm f4 on a cropped sensor. The difference is caused by the sensor on the cropped body. It doesn't change the focal length only the way the image is framed. So on a cropped body the 24-105mm frames like a 38.4-168mm lens.
For me personally I wouldn't recommend the 24-105mm lens for a cropped body because you lose the wide angle capability, then you get suggestions like "then you need the 10-22mm to cover UWA" obviously people have money to burn, the 17-55mm f2.8 EF-S lens would been a better lens option.
In your other thread, you mention indoor photography, personally wouldn't use the 10-22mm either, it distorts the image due to the fisheye effect, you would be better of with a prime lens for this purpose.
Ok, your boss has said, buy a camera for work, but you'll have almost sole use of the camera and lens(es). I would base the purchase around this rather than kit for your motorsport (sorry) and the 5D MKII would be better option for this than the 7D.
Why - The larger sensors (FF) generally provide more control and greater artistic flexibility, but at the cost of requiring larger lenses and more expensive equipment. so there's pro's and con's to whether you go full frame or crop
The 24-70mm would be an ideal lens to use for your work photography, warehouse express has this package currently at £2549.00, Kerso (Ian, you can PM him here on TP) would probably be able to do this package slightly cheaper, but not sure how this would play with your finance department.
The 70-200mm f2.8 (non IS) would be a perfect partner to this lens if you when FF, but it depends on finances and what you boss will agree too.
