Hi guys, its me again

This time im asking for a T-Converter on my 70-300L.

Few questions:

- Does it even make sense (i guess because its a damn sharp lens, but will it focus on my 6D?)
- Image quality?
- If it all would work, and since Canons Tele converters dont work on that lens, which Kenko has got the least IQ degradation?

Thanks in advance!

I tried this combo on my 7D...hunted focus a lot. Haven't tried it on the 6D yet, I should and see if it's any different.

I use the kenko in my sig with the 70-300L and 5DII. AF is fine outdoors, but hunts in low light. The IQ isn't bad, actually.

I'll give it a shot tonight if I have a second. I wish Canon would make the 6D AF at f/8 like they did the 5DIII....might help with the keeper rate.
