I'm 0-2 when it comes to teleconverters. Wanted to get opinions about image quality with the sigma 1.4x between a sigma 150-600 Sports and canon 7d2.
I have a Canon 1.4 mkIII and Kenko Pro 300 1.4 and neither work with that body/lens pairing.
Don't care for the image quality with the canon extender between the 7D2 and canon 400/5.6 prime lens.
Thanks
