One hundred percent true. But when I shoot sports I have the 300 F4 on the crop because it is equivalent to 480 mm relative to the same lens on the full frame. I use the 70-200 on the full frame. This first gives me the maximum reach and the second is best for when the action is close.
The semantics of this are interesting. It reminds me of something in aviation. Cessna put a 160 hp engine on the 172. Then, later you could upgrade to 180 hp by simply changing the prop. So was it really still 160 or was it 180? The answer is that it is the combination of the two that results in one or the other.
Use it for any reason you like mate! But to use your engine analogy don't try and tell me that changing the prop increases the size of your cylinders!
