do you think the new Canon 28-300 L IS lens is any good for aviation photography. Is the quality comparable with the 100-400 L lens...
I almost bought a 100-400 L lens to replace my current 75-300 IS lens, but as I have also the 28-135 IS lens I really like the idea of the 28-300 which mean that I don't have to change lenses anymore (reduce the risk of sensor dust).
Any opinions or experiences with that lens? I know is more expensive than the 100-400.
As always, thanks for your help in advance.
