EOS R6 Mark II Exposure compensation in Av mode / Backbutton focus

jmoost — Tue, 30 Jan 2024 14:16:15 GMT

Hi,

I have read some forum threads and watched some youtube video's but I can't seem to find the answer. I really want to buy an R6 mark ii but I want the buttons to work in a way I am used with my Ricoh GR iii and (sold) Nikon.

1. I have BB focus set to AF-ON.
2. EVF / Screen of my Ricoh is always showing an exposure preview, based on settings and picture profile
3. Half pressing the shutter wont do nothing, metering is always metering and focus is on AF-ON button.
4. When I want to overexpose on purpose in backlit situations, I can use a dial on the back to EC plus or minus
5. The set EC stays the same, only when I change it back to something else or back to 0.

What I would like to have:

1. in Av mode, metering always on and shutter half pressed does nothing
2. I want to BB focus with AF-ON
3. With the Quick control dial 2 I want to change the amount of EC plus or minus.
4. EC should impact ISO or shutterspeed, can you set that?

Hope you all can help.

Program the [SET] button for exposure compensation.

Is the camera set to use the AF-ON button only for AF only with the shutter button decoupled from AF start at all. Exposure Compensation in Av Mode will adjust the shutter speed this will work differently when Auto ISO is used. The camera will try to use the lowest ISO possible. With mirrorless the camera is always tracking even when the AF-ON button is not being pressed. The shutter button is metering start and must be pressed to take a meter reading. The quick control dial on the back of the camera can be set up for EC. When the set button is programmed to do so.

Thanks, most is clear.

1. The 'always tracking' AF function can be disabled if i am correct, so the AF will only work when the AF-ON button is pressed.
2. Shutter button is metering start, but a mirrorless camera always shows an image preview right? There is always a 'live view' based on picture profile and Av reading without the shutter half pressed?
3. You sure the quick control button nr 2 can be set for EC in Av mode? And not only button nr 1?

You will probably not be able to duplicate the layou and functionality of a different camera brand. If you could, then that could raise copyright infringement issues.

I suggest you program the [SET] button for EC.

I know but the main question is fairly simple. Can you set the custom dial 2 to EC in Av mode?

"With mirrorless the camera is always tracking even when the AF-ON button is not being pressed."

Demetrius, with all due respect, that is not my experience. Before the R6II the menus had an option in the Focus section for Continuous focus on/off. If Continuous was ON the camera would try to focus all the time, which was a great way to drain the battery, so one would normally turn that off and, if tracking was required, use Servo mode with tracking for whatever kind of subject one wanted.
In the R6II, which I have in front of me, there is no such option for Continuous. It appears to have been removed. If I use BBF without servo, once focus is achieved and I move the camera, it does not attempt to find focus at a different spot, I to re-tap the AF-ON or half-press the shutter button (if I am pointing elsewhere). If I have the camera set to servo, holding the AF-ON will focus with a moving object.

As to Exposure compensation, the default is set to allow the main control wheel at the rear to adjust exposure for several seconds after focus lock, so one just winds that around as required. If that is not enough time, simply re-tapping the AF-ON button will re-activate that function. EC control has always been associated with the rear control wheel of cameras that have that control.

I was referencing if the camera was set to continuous AF. I don't know how the OP has there camera set up.

when you mean custom dial 2 what precisely are you referring to? The default to change EC in Canon cameras has been what is shown here as Quick Control Dial 1. Do you wish to move that Exposure Compenstion function to the other dial in front of the shutter button, which Canon calls the Main Dial - see item 3 lower image?

Hi Trevor,

Thanks for the help. I mean Quick Control Dial 2. I would like to set this to EC in Av mode.

And as for the time the EC is set, can you just set it to a longer time, and not a few seconds?

Re: Exposure compensation in Av mode / Backbutton focus

Tronhard — Sun, 28 Jan 2024 20:19:53 GMT

Good, thanks for that clarification. By default, unless something has been customized already, the default for Quick Control Dial 2 actually IS exposure compensation. If you are using BBF, and you run out of time to set the EC value, simply half-press the shutter button, which is no longer impacting focus, and you can then get a chance to rotate the dial.

Ok that would be great.

Does the EC on Custom Dial 2 also work without half pressing the shutter? On my Ricoh the preview on the screen always shows what the camera is ' metering / reading'. at that time. Without shutter half pressed. I can then use the EC dial to up or down the exposure. Is that possible on the R6ii too?

If you have just focused it will work for a few seconds, if you have focused but don't have enough time for EC, you can either press AF-ON again or half press the shutter button. I don't see a feature to hold the option for EC dialing for longer.

I think I get it. So when in Av mode I half press the shutter and then set the EC for example to +1,5. After i release the shutter button the EC will stay at +1,5 unless i change it back. So after that i can BBF and take the shot. Even after i turn off the camera the EC value will stay +1,5.

IMO the EC works best on a Ricoh or Fujifilm with dedicated dials.

I guess thats it.

Your summary is correct. I shoot with Fuji as well, I have an X-T4, Nikon Df and Sony, which all have dedicated dials. Personally, perhaps I am so used to Canon (shot for 4 decades), being able to manipulate the EC with my thumb while controlling AF and Exposure lock (via the * button), it is actually faster - but one develops muscle memory reasonably quickly!
Good luck with the rest - the R6II is an awesome camera!!

“ By default, unless something has been customized already, the default for Quick Control Dial 2 actually IS exposure compensation. “

I would beg to differ. The functionality of that rear dials and controls are as follows, AFAIK.

I recently reset my camera after a recent firmware update. I never change these settings. My mode dial is actually set to Av mode. No idea why it says M mode, or any mode for that matter.

With a fixed ISO, turning either Quick Control Dial changes the exposure, but it is not adding compensation. That can be achieved with the [SET] button and the Main Dial. The EC setting is retained from one shot to the next, too.

[EDIT]. Correction, I do change these settings. I disable the Control Ring on the lens. I believe it defaults to Exposure Compensation.

Bill I think we are discussing at cross purposes - the settings are for Manual mode as it says on the top, I was addressing the OP's question which is when the camera is in Av mode, where that screen does not apply. I tested the settings on three different cameras: 80D, 5DsR and R6MkII in Av mode before responding.

As I noted, the camera was in Av mode when I captured the screenshot. As you switch to modes other than M, one of the controls becomes Ev, exposure compensation, control.

I bring this up because the OP is saying the setting isn’t retained from one shot to the next. I’m saying that it shouldn’t because EC is not being dialed in.

I think I figured out why it says M mode. The controls change their functions in different shooting modes. For example, the Main Dial sets Tv in M mode, but it switches to Av in Av mode. The rear dial switches from EC to Av in M mode.

But that does not explain why the EC settings are not retained from one shot to the next. I like to use [SET] for EC because I get the same behavior in any mode.

Hi, i think i found my answer to this.

in this video at around 10.02 the guy dials the EC with the Quick Dial 1. The one on the back of the camera. He does not touch his shutter while dialing in the EC value.

https://youtu.be/CnzGrTaiX6o

i only would like to have this programmed to the Quick Dial 2 on top of the camera. The flat button near the AF ON button. But i could deal with it on the backwheel.

thanks!
