Canon gives you more stuff. Wow, I have the Sigma 2x. I didn't realise how much smaller the front element was compared to the Canon. I'm guessing that your going to selling the Sigma. 5D mkII | 35L | 16-35mm F4 L IS | 50mm f1.4 USM | 135L |

Actually it is called gray code CircuitR wrote in post #13638087 Wow, I have the Sigma 2x. I didn't realise how much smaller the front element was compared to the Canon. I'm guessing that your going to selling the Sigma. Thanks for sharing. Not only the front element is bigger, but the protrusion into the back of the lens is larger diameter too. Both teleconverters will fit Canon lenses that are designed for a TC but the Canon TC won't fit some Sigma lenses that don't have a large enough opening in the back of the lens. My 50-500, for example, fits the Sigma TC fine but not the Canon.
