EOS R6 won't focus on the spot I choose

DayB — Thu, 11 Apr 2024 13:58:23 GMT

Hi All

I have my camera set up in animal eye autofocus and servo mode. I have back button autofocus set up so when I press the AF-On button, it focuses and then when I press the * button, it activates eye autofocus.

My issue is that when I set the camera for single spot focusing, no matter where I move the white square to, the camera focuses where it wants whether it is inside the white dot or not. The little blue squares will lock onto an object and it just focuses where this blue squares appear.

I have tried one shot and servo modes but this doesn't make any difference. I have tried on different lenses and no change. I updated the firmware and tried a reset on the camera.

So either I am being a bit stupid and making a fundamental error, (which has been known on more than one occasion) or the camera could do with a check up.

Any ideas that I may have missed please?

TIA for any help 🙂

Welcome to the forums, DayB. We will need a little more information about your camera settings and shooting scenario.

What are you trying to photograph and how far away is it?

What lens are you using? Are you using Servo AF or One Shot AF?

Why are you trying to use Spot Focusing, while expecting the camera to perform Zone Tracking?

Hi there

Thanks for your reply 🙂

I am trying to photograph kingfishers (hence animal tracking). Distance is variable and could be 30 meters or further. I'm using a 500mm lens with it and the camera is in Servo AF. Im wanting to be able to move the white square onto the kingfisher if it is partly hidden behind foliage to get the camera to lock onto the bird and then use the eye tracking to fine tune the focusing. This is standard for shooting animals.

However, even if I put the white square over the kingfisher (in this example), the camera still will focus on foliage that is closer to the bird and well out of the white dot area. As a result, I am having to manually focus roughly onto the bird and then animal eye autofocus kicks in. But it will just as quickly then focus back onto the foliage.

Hope this answers your questions?

“ I'm using a 500mm lens with it and the camera is in Servo AF. “

What lens are you using? Is it a Canon lens? Is it an RF mount lens? I ask because not every lens is compatible with the advanced tracking features.

If you are using BBF, then why is the camera refocusing? Are you causing it?

Re: Canon R6 Focusing

DayB — Mon, 08 Apr 2024 20:29:56 GMT

I'm using a canon 500mm f4 mk ii lens but have also tried it with a canon 80-200mm f2.8 mk I lens. Both are EF lenses using the adaptor.

Apologies but I don't know what BBF stands for?

My query is exactly that....why the camera is refocusing? I don't think I am causing it but I can't be 100%...hence my question on here incase I am doing something I'm unaware of

So this video may better explain my issue. You will see initially that the white square is placed on the dragon in the foreground and the camera's blue squares hit that when I press the AF-On button on the back of the camera (as have back button autofocus set up). Then when I move the white square to the pot in the background and press the AF-On button again, it still focuses on the dragon in the foreground. What I don't understand is why moving the white square over the pot doesn't get the camera to focus on the pot...why are the blue squares still going for the dragon?

DayB, everyone has there own methods but I don't use Servo for stationary subjects. I shoot a lot of birds and use the "Fine" AF point in "One-shot AF" mode. That allows me to isolate my birds from any clutter in front of or around it. I will sometimes switch to Eye tracking/servo when really close, say, under 30 feet and even that depends on the size of the bird. Any other time, eye is disabled. I will also use Servo with Face+Tracking for Birds In Flight (BIF). I have C1 configured for BIF and have my control ring bound to my focus points. I can quickly activate Face+Tracking by turning my control ring 1 click. (FYI: Face+Tracking was removed as an AF point selection in the R6 mark II and renamed "Whole Area Tracking" in the AF menus, but it's the same function.)

Thirty meters is a reach for eye tracking with most smaller birds like your Kingfisher, even with a 500mm (I use the RF 100-500mm L), particularly on the 20mp R6. It will lock onto a birds face or body, but may struggle to find the eye and it's AI will just focus on the face or body. It may appear to be focusing on the birds eye, but it is more than likely focusing on the head/face area. At the distances you referenced, it's [eye detection] not going to make a lot of difference as the Depth of Field (DOF) is going to encompass the entire bird anyway, at least that's been my experience. My largest aperture at 500mm is f/7.1 and for the smaller birds, DOF only becomes a problem sub 30 feet (10 meters) and if the light is dim, which is typical for forest canopy and floor, I will up my ISO so I can use a smaller aperture and increase my DOF.

As for not being able to lock, as far as I know you can not lock focus in Servo. The manual for the R6 seems to confirm this in the troubleshooting section, page 829.

The acronym “BBF” stands for “Back Button Focusing”. When it has been “properly” set up, the [AF Start] function is removed from the Shutter Button. I suspect that you may not have reprogrammed the Shutter Button.

In other words, your camera could be refocusing because you are pressing the shutter, which causes it to refocus. I tried to find video content by Canon that explains the basics of BBF.

You probably just need to simply turn off all tracking.

Like Newton, I have my cameras set up to use Custom Shooting modes. I have C1 set for Servo AF, tracking enabled, BBF, and other settings. I think of this mode as “birds in flight” mode.

I have C2 set for Single Shot AF, tracking disabled, BBF, and other settings. I think of this mode as “bird on a branch” mode.

With your current setup when you press the * button to activate focus then the camera switches from your spot AF point to face + tracking, activates eye detection and starts focusing. The problem is that the eye detection doesn't take any notice of where your spot AF point was. So you actually need to do something different to get the effect you want.

That different thing is this set of steps... (screens from EOS R6, but its the same for R5)

Set the * button to AF + metering start - just like the AF-ON button, but then press the INFO button to get access to the extra settings, and make sure that the AF method is set to Face + tracking.

Secondly you need to make sure that eye detection and animals is the selected subject to detect. You can only change the eye detection setting while face + tracking AF method is selected, so do that if needed, then switch back to your spot AF point.

Lastly you need to change the initial servo AF point for face + tracking AF, and change it from auto to the middle of the three settings.

With these steps completed then when you press the * button the camera switches to face + tracking and eye detection is already active as is animal subject detection. However you will have an initial AF point - slightly larger than the spot AF point, but it will be shown in the same location and that is where the camera will look initially to find the subject. Actually the initial AF point is closer in size the the 1-point AF method.

What is important to realise with the EOS R5/R6 is that they don't do subject tracking at all when set to spot AF, 1-point AF, AF expansion cross or surround AF methods. Also eye detection for people or animals is only possible when the AF method is set to face + tracking. Zone AF will do subject detection within the frame of the zone, but it does not do eye detection.

Later models such as EOS R3, R7, R10, R50, R8, R6 Mark II can all do eye detection and subject detection with any AF method.

Hi there

Thanks for the time you spent searching for the above video. I did watch it all the way through and my camera is already set up this way. The shutter release is disabled for focusing. I'll check the below comments as well but thanks for your help 🙂

Re: Canon R6 Focusing

DayB — Tue, 09 Apr 2024 12:15:17 GMT

Thanks for your reply.

What I took from your answer was the usefulness of using C2 to set for alternative scenarios. I just use C1 at present but will start using C2 for birds around foliage and animals in clear settings. Makes perfect sense when I read that.

I used the kingfisher as an example as that was my last outing but I shoot deer and other birds. The songbirds are the ones I often have issues with as they sit between branches and pressing the autofocus may get the bird but also many times gets a branch and won't accept the bird as the target focus. That was why I was looking at trying to get a single focus point (using the white square) in order to tell the camera that that was the target and not a branch. Birds in flight don't have this issue so that side is fine and depth of field is also ok. It's just finding a way for me to tell the camera what a target area is when there are enough other distractions that can (sometimes) fool the autofocus.

Re: Canon R6 Focusing

DayB — Tue, 09 Apr 2024 12:18:43 GMT

Yes, this is exactly what I picked up when I read Newton's post.
Will definitely follow his and your examples and set the camera up for different scenarios.
As you said, birds in flight and birds in trees are very different scenarios and thus far, I've pretty much had C1 as my general wildlife settings. So definitely time to refine that and see how that works.
Thanks for the vid and the feedback...really useful 🙂

Perfect...yep, this is exactly what I was looking for.

Thank you so much for the explanation and the images...I'm very much a visual understander so this really helped.

You're a star so thank you so much for this 🙂

Re: EOS R6 won't focus on the spot I choose

photopro — Tue, 11 Jun 2024 01:49:23 GMT

Hello! i have the mark 2 which is a little different but the same issues can happen and this is my take after much experimentation and settings changes... first, the spot focus is flawless when using the touch screen. You touch the screen on any focus area and focus is achieved regardless of the foreground being closer. I experimented for an hour using different lighting and ISO and results were consistent with the touch screen. Why isnt viewfinder focusing as precise using the spot focus?.

2. by now we know, at least in the mark2 and i suspect the r6, that ALL eye/face focus, Animals, cars, etc. must be turned off in the Autofocus menu, and the custom button used for focusing with the spot must be set to focus and meter only, and not any eye etc. focus. The button customization will override the settings in the menu. ( i use C1 for eyefocus, and C2 with all that turned off). BUT you can have eye focus in the main menu and setup one button to focus with the spot and no eye focus; i think thats described above. My af on button is eye, the * button is focus and meter, no eye or face and it works most of the time.

3; i have seen suggestions to turn off Whole area focusing to use spot focusing. I believe that is incorrect. I tried it with viewfinder shooting, and whole area definitely works much better for spot vs. having it off. It also was better with the LCD touch focusing also. I dont know why you would turn it off, as the spot should be more effective when using the whole area, unless the spot overrides the setting and uses whole area anyway.

4; don't know if its available on the r6, but using the focus areas with the rectangular area, or expanded spot is a starting point for camera focusing, but there's no guarantee it will stay there. I suppose the sticky adjustment helps but as many have said, the 5dMK4 does not have these issues. I suspect it starts and stays within the designated area of autofocus unless focusing is not achieved on the subject. Sometimes i think the Mark 2 focus is so good its too good and makes one think its malfunctioning, when its doing its normal thing. Hope this wasn't confusing, my descriptions are not 100% accurate.

I've been following this issue of the proper settings for AF for animals and Eye detection. When I get to my R6 I'm going to try Brian's instructions. However if you want to share your solution I am interested.
