7D II settings question

Just browsing through the online manual, and it appears the 7DII has the same behavior in TV mode as my 60D - it auto selects the Aperture and ISO to meet the exposure level I select (I want to push to the right for Post noise handling).

If I'm looking to lock in an F/Stop and Shutter speed and let the ISO float, it seems I would need to go to Manual - but could I force ETTR with Auto ISO set on the 7DII in that mode?

I can't find a way to do this on the 60D, and it could be an tick in the "Upgrade - yes" column...

ISO should be your third option for exposure, not the first. It's the only one that directly effects IQ. That may be why there is no direct setting like you want.

However, if you shoot in manual and set the camera for auto ISO, it should give you something like you want, I think. I have never tried this. Maybe someone else has.

Yes, but on my 60D I cannot adjust the AEB while in full manual (it's greyed out), so I have no option for ETTR unless I choose a TV mode - but then the camera auto adjusts the Aperture before pumping the ISO.
I'd like the option of locking the F/Stop, forbidding the camera to drop it.
I'm wondering if the 7DM2 can do so.

I'm not too sure of the question but you can go to manual mode set the shutter speed and aperture and put it on auto-ISO. Then you can use exposure compensation to force the exposure to the right. I'm not exactly sure if that it what you are wanting.

If it is, you can also go to custom settings and set up the "set" button so that if you push it in and hold it you can change the exposure compensation up and down by turning the top dial.

Doc,

"You can go to manual mode set the shutter speed and aperture and put it on auto-ISO. Then you can use exposure compensation to force the exposure to the right".

Yes - that's what I want to do, but I can't on my 60D. Exposure compensation adjustment does not appear to be available in Manual mode.

"You can also go to custom settings and set up the "set" button so that if you push it in and hold it you can change the exposure compensation up and down by turning the top dial"

I have that function currently set for Flash Exposure adjustment - Exposure Comp is not an Option. Is it on the newer cameras?

When you put the 7D2 in manual auto ISO is available. Then, when you adjust f-stop or shutter speed, the camera compensates by changing the ISO. So yes, it will do what you want.

The bigger question is why do you want to manage exposure that way? Changing shutter speed or aperture does not add noise and degrade IQ. Changing ISO does and should be your last resort most of the time. In addition, putting your camera in manual mode with auto ISO really sets up an ISO priority auto exposure mode.

So you can easily do what you want. But why?

Rgs,

Thanks,

I understand that ISO can be set to float in Manual on either camera (60D, 7DM2). But can you ETTR in that senario? Can you lock your F/stop in TV mode?

As to why: I'm not happy with my Telephoto work right now. I'd like to set my Shutter to a specific point, take control of my DOF, and experiment with ETTR.
I'm seeing photos posted in the wildlife threads that have a clarity and sharpness I can't match - and I doubt it's the camera, as I've noticed that folks who post great images from the 7DII tend to have a history of great images with their older bodies. Hmmm....

It's starting to look like the software assumes that if I choose Manual, I mean it and need to control the whole show. If the options are the same with newer cameras, then I'll bare down and work with that.

I am sure you can add exposure compensation but I'm not sure how because the thumb wheel control on the back will be changing your aperture and so unavailable for EC. I'm sure there is another way but I don't know what it is. In the situation you describe I would either shoot in TV and monitor the aperture to turn the ISO up if needed. Or just shoot in manual and change ISO as needed.

Yes,on the 7D2 you can shoot manual with auto ISO and use exposure compensation to expose to the right.You do this by assigning exposure comp. to the new ring lever around the joystick on the back of the camera.You set your aperture and shutter speed and select auto ISO.This will give fixed SS and aperture and the ISO will float to achieve proper exposure.On top of this,while holding the new ring lever down,you can add exposure compensation by turning the top dial.

This will allow you to ETTR.

Hope this helps,

Robert

On the 7D II you can add exposure compensation in manual mode with auto-ISO by going into the menu to the exposure compensation menu. Or you can make it easier by going into the customs control menu and changing the "set" button for exposure compensation. After doing that you can push and hold the "set" button and then while holding it, turn the top dial by the shutter button to increase or decrease exposure compensation.

Auto ISO can be useful in sports when you have rapidly changing lighting (like sun and shade from clouds) and you are trying to keep a constant shutter speed and a constant aperture and don't have time to keep checking your settings and changing ISO.

I'm saying that on the 7D II you now have the option of exposure compensation while you are manual mode and auto-ISO. The original 7D can't do that so I expect the 60D can't either. In the Coliseum I shoot basketball in, I was using manual mode with atuo-ISO and the shots were coming out slightly dark to my tastes. All I did was bump up the EC a 1/3 of a stop and that solved that.


Doc

Gentlemen,

Thanks for your input on this - I may have placed one foot down the upgrade path .

That makes sense to me. Even though auto ISO should still be the third option, it may well be the best option in the situation you have described and, probably, in some wildlife situations also. Just another lesson as to why someone with more imagination than me designs cameras and software!

EC with Auto-ISO in "manual" mode is a new feature for Canon and is currently only available on the 1DX and 7D2.

you don't have to re-assign a button to do it on the 7D2

put camera in M - choose SS, Aperture and Auto ISO

press the Q button on the Back of the camera and use joy stick to move to EC (adjust as desired) - you are done
