Heres the question.
How does the Canon 300mm f4 IS L lens with a 1.4x conveter (canon L) compare to a Canon 400mm f5.6 L.
Now, what im thinking is, the aperture would be the same at f5.6, but the lens would benefit from IS, compared to the 400mm f5.6. I know the 400mm f5.6 is fast and bitingly sharp, but what would the IQ of the other combo be like compared to it. The lens would be for aircraft photography.
Any insight would be grateful.
Thanks
