I need a sports camera and I'm not sure which one to get. I already have a canon 70-200 f2.8 is so then Canon would make more sense however the sony has far better specs so it would also make sense with a converter. Which one should I buy! Another thing will the converter slow down the lens and quality much?

Please help.


I didn't find the right solution from the Internet.
