When the 5Dmk4 was announced, Rudy Winston did an announcement video and in it he said it could do f8 focusing but he specifically said with the version 3 teleconverters. Is that a requirement? Has anyone tried testing the 5Dmk4 with version 1 or 2 TCs? Like maybe a 100-400 II with a 1.4x tc2 or a 70-200/4 IS with a 2x tc2?

Thanks

I am not at all sure when I would be able to get to this, but I do have version 2 T-Cons i can test at some point.

OK, here is what I have, all tests with EOS 5D Mark IV

In a nutshell, you get AF @ f/8 with every T-Con combination I tried equaling f/8.

If you want to work with all AF points, it has to be a MkIII T-Con

EF 500mm f/4L IS MkII With EF Extender 2X MkII RESULT: AF Works FINE! 9 AF Points are selectable.
AF points three positions left or right, and 1 position up or down from center are available. Put another way, 7 across center, 3 up and down center. Total 9 AF points.

EF 500mm f/4L IS MkII With EF Extender 2X MkIII RESULT: AF Works of course, All AF Points I think.
Lost count, looks like an awful lot of AF points selectable! 11 across, 7 up and down, and you don't need to stay in line center.

EF 100-400mm MkII with EF Extender 1.4X MkII RESULTS: AF Fine again. 9 AF Points are selectable.
Same as 2X, only 9 AF points available for selection. Same result with SIGMA and Kenko 1.4X

I don't have a Canon 1.4X MkIII yet, but suddenly I have a reason to want one ;)

Yes, he specifically mentioned the v3 for compatibility and the B&H event today.

It is already on the B&H site if you want to learn more about the 5D4. I highly recommend it.

Awesome Jake. Thanks. I wanted to make sure to be as future proof as possible. I was thinking about picking up a cheap used 1.4 II but I'll stick to the III if I go that route.

The manual which I found a copy of somewhere on line lists which points are available for which combinations of lenses and which versions of converters.

The great news is that what they specify in the manual matches Jake's real world findings above.


A coupla bodies and a few lenses

I was just about to say that it takes no more than reading the manual to find this out. But you beat me to it.

I think the point of testing was that sometime, often in fact with Canon, a thing will be rated conservatively, and one can at times push Canon's expectations and get results a little better than expected.

Until we actually test, we don't know if this is one of those cases or not.

But yes, all this test proved was that what Canon printed is in fact accurate.

Also, please note the initial question. There may have been some confusion as to whether AF @ F/8 was possible at all. This test clears that up.

All in all, having shot with 1D bodies for so long, this is quite amazing to me to be able to use more than just the center AF point @ f/8! And to get 9 af points @ f/8 on a "bad" combination is outstanding and better than any 1D body ever offered (1Dx not included)

The manual says nothing about the actual performance, of course. It only says everything there's to know about which AF points you can select with different lenses and converters.
The 1DX allows f/8 focusing with center point, or center point with four point expansion only. So five points is max, where only the center one can be the primary one.
Probably the result of the 1DX getting this capability as a fix after launch, but the 1DX Mark II was designed to provide f/8 AF. Then the 5D Mark IV just follows suit.

Seeing how I don't own the body at least yet, I wouldn't know its in there in the first place. I am mulling over longer lens options than my current kit offers and I just wanted to make sure I was keeping it as future proof as possible given when we know now.

These will have to be later tests. i did the above confirmations in my office @ night.

In the case where I had both MkIII and MkII side by side, (2X on 500mm MkII) Even in the office, it was clear that with the MkIII T-Con it was not only giving me access to more AF points, but it's response in this case appeared superior.

Previously with the bodies I own, I have been reporting little to no improvement in performance going from II to III 2X t-con. But I've never had a current state of the art body like 1Dx, 1Dx to test it on. With 5D4 I am finally testing on a body closer to the current state of the art (ie: 1Dx2)

Well, I've used my EF 300 mm f/2.8L IS II USM quite a lot, both as it is and with converters. Both my converters, 1.4X and 2X, are version III. Here performance is very good, with all three combinations. But they don't exceed f/5.6, of course.
If I use a 2X converter on my EF 70-200 mm f/4L IS USM, or use the 1.4X with my EF 100-400 mm f/4.5-5.6L IS USM, then the most prominent limitation is of course that it's only the center point and the four nearest assist points that are useful on my 1DX. Especially with the older, and long range zoom, 100-400, general performance suffers a bit. But it works, for sure.

Um,... I did some tests.
https://photography-on-the.net …showthread.php?​p=18140093

In short, the 5D4 is such a huge upgrade in AF performance with T-Cons vs. any other body I have shot, it's no contest. It doesn't matter if you use MkIII or MkII, the AF speed and accuracy is off the charts vs. any older bodies.

I have to assume that right now only the 1Dx2 and 5D4 are this capable. 7D2 is slow in comparison.

I am literally blown away by the difference.
