Help Wanted -- 5D Mark II or 1D Mark IV?

[Jon Ruyle]

Just so we're clear, I was making the comparison between comparable effective FOVCF.

Both clear and valid. []

My assumption also was that the 135mm f/2 was an exceptional lens optically, and comparable to the 200/2.8 if not exactly as good as the supernatural 200/2.

Sure, the 135 is nice. But if you use it wide open and crop it, it won't compare with the uncropped 200 f/2.8 used wide open. I'm just saying you don't pay all that money for full frame and get nothing in return.

Obviously if performance includes frame rate, the 7D leaves the 1Ds in the dust.

Well, if performance = frame rate, then yes. Those who require FF with 7D+ frame rate need not consider canon.
