Hi All,

I've had my heart set on buying the 100 - 400L for a while now, mostly for Air shows. But recently I've heard a lot about the 300 4L.

Obviously the 100 400 gives more versatility but I'm wondering if the sharpness of the 300 is great enough that cropping in will give similar results to the 100 - 400 at 400mm??

Looking around online most sample pictures with the 300 4L are of wildlife.

Does anyone have experience with this lens at an air show? Any thoughts on in general on cropping to get similar high end range as the 100 - 400?

Thanks for any thoughts/suggestions!!

Well I would imagine cropped the 300mm is similar to the 100-400mm. However if it produced similar results you may as well get the 100-400mm as it would be much more versatile. Personally I would go with the 100-400mm unless you were only going to need 300mm.

A lot of airshow photographers see the 100-400 as virtually unassailable.

It has a lot going for it and if you don't mind push-pull zooms, it's a bit of a no-brainer. I usually use a combination of a 300 + 1.4 and a 70-200. But a 100-400 will give you at least as many options.
