Sorry for the late reply. I used a 5d3 with the 16-35. Shot @ 16mm ISO12800 1/80 F2.8. Strobe rear left with a 1/3 CTO on a 580EXII 1/64 though a softbox.
I only have a 7D at the moment so I wonder what type of coverage I'll get using the cropped frame? It's obviously not going to be as wide as your photo but I would dearly like to see an image take with a cropped frame camera and the 16-35 if you had one. I just want to make sure I'm buying the right lens. I love the f2.8 DOF as it can be used very dramatically even in motorsports and it gives me a much better quality image in low light which at times can be an issue.
Any help you could give me with this would be greatly appreciated! I would certainly owe you a beer!!
