It's like comparing a car to a lorry. Both are vehicles, but each can do things the other one can't.

Note that E-TTL pre-flash isn't just one single flash. A series of flashes, encoding binary data, are sent first for each E-TTL flash group to do the measurement. Then a longer series of data is ...

I would assume that's why Canon created the concept of setting the flash up via the camera's menu system.

You can indeed vary the exposure with a fixed aperture. The camera, or you, can change the ISO or the exposure time. The time can only be changed within certain limits, since you can't have a time ...

The 580 EX works, but does not support setup through the camera. You have to set it up on the flash itself. Flashes like the 600 EX II-RT will also support everything the 1Ds Mark III can do via ...

I don't have any 6D version, but it sounds like the 6D Mark II works the same as the 1DX. It got a lot of critisism, and the 1DX Mark II is very different.

I can't say either, not seeing your setup. The pre-flashes are much weaker than the "real" flash. Perhaps your manual flash doesn't see them? When using optical communication with an E-TTL slave, ...

E-TTL can do what you are asking for, provided you use E-TTL for both flashes. Due to the extensive pre-flashing E-TTL uses, a "stupid" slave, just firing when it sees any flash light, can't be used.

This seems to depend on the camera body. My 1DX Mark II does implement all the modes, for example, for video as well.

The first flash supporting the setup through the menus of the 1D Mark III and 40D (the first cameras with this feature) was the 580 EX II .

Exactly. Where the light from the controlled flash overlaps that of the manual one, you get overexposure, unless you tell the controlled flash to illuminate less and lower the strength somewhat of ...

The buffer starts filling as soon as you take the first picture. At the same time , another process in the camera starts emptying finished images and push them to the card. If it's the first or ...

Is it a Canon lens? Sometimes third party lenses don't give all the functions you otherwise can get.

There's no front wheel, but there is a rear one. Or, using Canon's terminology, there's the main dial, near the shutter button, and the quick dial, at the back of the camera.

The sorting option has been in EOS Utility for a long time. Handy if you want the most recent image to show up on top.

I don't even have any 6D Mark II , but Canon publishes manuals for a reason. It clearly states in the manual that the interval timer doesn't work in conjunction with using Live view, movie ...

Start augmenting your stills with video, and the cards can't be big enough.

Yes, the AF-ON can have other roles. Exactly which depends on the camera. The least complex is OFF, i.e. it doesn't do anything at all.

Apparently you had to add that, since how would I otherwise know? I don't want to be rude, but without knowing all facts it's impossible to give accurate answers. Now when I know that piece too, ...

You have to delete the files from the card and reset the camera's numbering sequence. The camera will remember the last used number and compare that to the highest number present on the memory ...
