I have the 7d & 5d3 along with 100-400 and 70-200f2.8version2 and the 1.4v3 extender

I usually use the 5d3 and 70-200 combination and it its superb for the likes of BTCC (British Touring Car) but at times I need more reach, for example Silverstone and Brands Hatchh circuits.

I find the 5d3 focus ability much better than the 7d's

What would be the best option?

7d 70-200 & 1.4 = 157-448 at f4
5d3 70-200 with 2x mk3 extender = 140-400 at f5.6

I tried the 5d3 with 100-400 and 7d with 100-400 and results weren't amazing (like the 5d3 & 70-200f2.8) and it struggled as it got dark

Any ideas?

I guess the 300f2.8is is what a lot of photographers (press) use but that has no zoom.

Many thanks in advance.

This won't be much help. The approach here is to not use a teleconverter, but a single super telephoto lens, a Sigma 150-500mm.

Exposure Bias: none

White Balance: Auto

The Sigma lens goes on the camera and stays on. There's no concern about losing or dropping extra devices or introducing dirt into the camera. The effort goes into taking pictures instead of swapping gadgets.

It's decent but not great. The 70-200 f/2.8L IS MKII is an awesome lens. It is super sharp and the colors are vibrant. With a TC attached you lose the following:

Sharpness
IQ
Contrast

And the most important thing is you lose the natural setup of the optics that provide the creamy bokeh. Even when used in a panning environment you can see the different between the two. End result is flat photos and that do not look as good as they could.

Would highly recommend a solid prime to tackle that longer reach. Or only use a 1.4X TC. Results are much better but still noticeable.

Thank you for your reply
I guess that's the 300f2.8 or a 400 prime then?

How do you thing the mk2 70-200 with x2 extender would compare to the 100-400 for IQ and focusing etc??
Thanks again
Colin

I've used the 300 2.8 and find it works very well. I've also used a 1.4x converter on it and still had quality images.
