Canon 6D Mark II Autofocus With Teleconverter

Sigma 60-600mm For Canon



"Hi,

I have a sigma 60-600mm sports lens with the sigma TC-1401 teleconverter mounted on a Canon 6D Mark ii. I am unable to change or even see the AF points on my camera. By default only the center focus point is there and none of the other focus 44 AF points show up. Is there any way that I can (fix) that?

Thank you."


Hello Arun,

Thanks for your question about autofocus with your Canon 6D Mark II, a 1.4X teleconverter, and your Sigma 60-600 lens.

The quick answer is no. You lose all autofocus with your 60D Mark II for all focus points accept the center point. I called Canon USA before I purchased a new telephoto lens and was told it "should be fine."

I now have a Canon Pro "L" lens, the Canon 100-400mm f/4.5-5.6 IS II USM and I lose autofocus with the 1.4x teleconverter also. The center focus point only shows up when I am in Live View mode.

Canon Teleconverter Autofocus

Only f/4.0 lenses and faster, like a Canon 300mm f/4.0 or a Canon 70-200 f/2.8 will maintain focus points. I've heard that the newer Canon DSLRs will maintain autofocus at the smaller apertures, but I don't have any proof of that.

I tried the teleconverter with both my 70D and 5D Mark II-they're both "old" in this technology driven field-and both don't give me the autofocus I want with the Canon 1.4x teleconverter II.

Sorry for your troubles, Arun, but that is the limiting feature we face with this lens combination.

Thanks again,
Bruce

"I have the canon 6d mark ii for shooting video. The white box that focuses when you touch the screen turned black/gray and would not focus when I touched the screen. Why did this happen."

Hi Brycelyn,
Thanks for your questions about the focusing issue with your Canon 6D Mark II when shooting video. Sorry for your troubles. Your 6D II is a fine camera.

6D Mark II Focusing Failure

The change to black/gray is the 6D Mark II telling you autofocus can't be achieved or isn't available. Without knowing your camera settings or the exact situation you were shooting in, it's difficult for me to diagnose the problem.

Can you send a photo of your 6D Mark II screen and describe the situation as well as give me your camera settings when this occurs?

That will be beneficial to you as well as other 6D Mark II shooters.

Thanks so much,
Bruce
