How to set 2 priorities aperture & shutter-speed on Rebel T6 ?

[Dianoban]

Camera & lens: Rebel T6 & EF-S18-135mm f/3.5-5.6 IS STM

I am going to take pictures of elementary school kids. They are moving constantly and the ambient light, shine, cloudy, rainy and shadows, is also changing rapidly.  I need an aperture F11 for a reasonable depth of field and 1/250s shutter speed for freezing the motions.  Can F11 and 1/250s be set up on Rebel T6 simultaneously and how, please?

Thank you.

Tv (Shutter Priority) Mode isn't appropriate for the OP's situation. It would be best to use Av Mode with an aperture of F/4.5 or F/5.6 when I was still shooting with an APS-C camera. With Full Frame I usually shoot at F/7.1 or F/8. Stopping down too far would result in unintended things (distractions) being in focus. Which is something you would want to avoid. F/11 is unnecessary for what the OP is doing. Using Auto ISO with upper and lower would be a good choice too. Unless the OP is using flash whether that be built-in or an external speedlite. The camera will ONLY use ISO 400-800 in that case. That's how Canon's DSLRs work the EOS R series cameras don't behave this way. A lot of times it will push the ISO as high as ISO 3200 or even higher.

Yes, exactly. 

Do bear in mind that increasing ISO can lead to image noise, which can become noticeable and objectionable at extremes.

Why is Shutter priority not appropriate? The OP's concern is wanting to stop the action of elementary kids moving around. There's a certain minimum speed needed to do that.

The OP is also concerned with Depth of Field, which is why they are looking at f/11 as an aperture. 

As I have commented, I believe that limiting both to specific values is severely and unnecessarily limiting their options and making it hard for themselves.  Given that, one has to step back and leave their assumptive values aside.  For a subject group the size of a school class, depth of field is likely the biggest issue, and as I demonstrated in my lengthy post, an acceptable DoF can be achieved using a much smaller f/value, yet still yield a hyperfocal solution.  By opening up the aperture and using an auto ISO of modest range, they have much more flexibility to deal with movement and changes in light intensity - given the parameters I mentioned for location.

Thank you.

I'll set my camera F/8 and ISO800. This will probably provide a shutter speed around 1/200s even in cloudy day light. 

[Dianoban]

Thank you.

I decide to set my camera F/8 and ISO800 which will provide a shutter speed around 1/4000s in sunshine and 1/200s in cloudy day light. 

[Dianoban]

Thank you.

My subjects are constantly moving running jumping twisting and rolling kids.  I will not take pictures of any group standing or sitting still.

I tested in the last few days and found that the if my camera was set as F/8 and ISO800, this combination setting would probably provide a shutter speed around 1/4000s in sunshine light and 1/200s in cloudy day light.

Hi Dian:
What shooting mode (Av, Tv, M) do you now have the camera set in please?

[Tronhard]

Hi Dian:
It sounds like this is not your bulk standard class photo exercise! I had just inquired about your shooting mode as you were responding to me! 🙂  Given you have set the ISO and aperture and the shutter speed appears to be vairable, I would guess you are now using Av mode, is that correct?

[Dianoban]

Thanks.

The setting is as this: Av mode, f/8, ISO800, and leave shutter speed to the camera.  I hope to get a shutter speed 1/4000s in sunshine and 1/200s in overcast cloudy day light.
