Well today outside we had cloudy weather so I had even light, well it seems with the kenko at f5.6 it gave me a correct exposure at 1/60th sec and the canon gave me 1/30th sec which is kind of weird, I wonder why?

Does the Canon TC have a larger diameter lens to allow more light in? Did the aperture change or are both TCs reporting the correct aperture?
