As a person who didn't use rear button focus at all I found this information very helpful. I shoot underwater video and stills. I see how this can be applied. Its a journey on my R5 and you have been helpful.

My R5 has single point BBF set on the AF-ON button and have assigned Eye Detection to the STAR button. It doesn't get any easier than that, it's so cool to be able to assign different functions to various buttons etc.

Just bought an r5, this video was perfect, set up bb 2 button in 10 minutes (had it on my 7d). Thanks, great help!

I use a combination of front and back shutter buttons. My front shutter button is set to tracking with animal or bird eye auto focus all the time since it works the best and I enjoy using it. For sudden action or birds in flight or almost anything I only need that front shutter button. I have one back button set up to drop the shutter speed for a lower iso and a second back button set to switch to single point auto focus To grab a single subject out of a busy background. Either of the back buttons will override the front button's auto focus settings if you hold 1 of them down 1st . There's no reason not to also have the front button set up and I have a fast shutter speed so that I can quickly respond to action or anything with only the front button and nothing else needed. For those special circumstances I can use one of the 2 back buttons. This is working well for me with my Sony and my Canon system.

Great to the point video without the uneeded stuff!!!

I have my R5 set up so that the single point focus is on the shutter button, and the back button gets the camera in eye tracking. You get the single point focus on the person, animal etc you want tofocus on, then hit the back button to jump to eye tracking. I think this is the quickest and easiest way to switch modes.

very good video. combining this with Fv mode is making me understand and act faster. thanks

Awesome, I'm glad it was helpful.

Thank you for this video. I have been looking for information on the Info Detail tab when in AF Servo mode. I do use dual back button focus and had it set up like yours but just changed it yesterday and am going to try a different configuration by not using face tracking for birds in flight. If I go back to using Face tracking in AF Servo, I will now understand what the Info Detail setting actually does.

Great video, thank you. Would love to see an even more detailed one about customizing the R3 with all the increased ability like eye tracking, etc that would be covered. Subscriber.

I would really like to do some work with the R3 too, as I really want to test the Eye AF. Unfortunately, I don't get free gear, so I'd either have to rent or buy it. And the kind of testing that goes into a subject like this requires more time than a short term loan or rental simply because you need a lot of shutter time to really understand how things tick. Ultimately, that means I don't have an R3 presently, and likely won't have one any time in the near future.

you can also do three rear button focusing

Is there a way to single-button toggle between animal and people auto eye focus other than assignment of two of the custom mode buttons?

Unfortunately, no. The only way to change the subject to detect is to go through the menus.

I used back button focus for 3 years shooting sports with the Canon 5D MK4. However I have found leaving the shutter button on it's default (focus and exposure) is actually more efficient. Why not let the the camera do some of the basics task an image so you can concentrate on other things, such as composition.

I suspect what's most efficient is going to depend heavily on your style and subject matter. I find myself in a lot of situations where not using back button focusing has been a much bigger hassle. Frequently, I don't want the camera to constantly refocus between shots, and I've been burned by switching the lens form AF to MF then forgetting to switch it back later on. Though your comment prompted an interesting though: given that mirrorless cameras have near 100% AF coverage, one of the points for BBF in the past, being able to focus and recompose without having to be in one-shot mode, isn't really an issue anymore.

I'm glad that works for you. I tried that, and it was the worst possible option for me. Having to push a button to negate an action isn't something that clicks with me. It's much easier for me to push a button to initiate the action I want or not push it if I don't want it. This is also an example of why I think it's a good thing that cameras are as configurable as they are now too. You can get the optimal setup for you and I can get the optimal setup for me and those setups can basically be completely opposite in function.

The problem with leaving focus on the shutter is that you can spend all this time getting focus right and then when you snap your shutter it changes the focus plane. Back button gives the best of both worlds vis a vis single shot v servo. Press and hold for servo. Press and release for one shot.

Can you have back button focus with animal eye detection and keep AF and metering on the shutter for initial metering?

@PointsInFocus

So you have 2 options, I think. You can't save the subject to detect to the focusing button (though that would be a really nice feature to have), but you can save the AF method. So one option is to configure the shutter button to be AF+Meter, and use whatever AF method you want (spot, zone, expanded, etc.), then set the AF-On button to AF start, and set it to always use the "face + tracking" AF method. This would also require the subject to detect to be set to animals, and eye detection to be enabled. The second option would be to set the AF-On button to "eye-detect AF" and that will automatically switch to the face + tracking (full area) method and turn eye detection on. The only thing it can't save is the subject to detect, so you'd have to always be in say animals mode, for it to detect animals. I suspect, this is probably closer to what you're trying to accomplish. Either way, the AF-On button will override the shutter half press AF function, if you're pressing both of them simultaneously. One other thing, with back button focusing, the AF-ON button will also start the meter, so you don't have to half press the shutter release, then press the AF-On button. Hope that helps.
