I purchased a 2x Kenco TC today, I was under the impression that using a TC that you loose F stops
I tried it in the shop on my 400D & Sigma 70-200 2.8 and was suprised I was still getting 2.8
Is this correct or is it just fooling the camera, have nt been able to take any shots yet but will do later
