6D - Minimum Shutter Speed

I believe you can only set a minimum shutter speed when using auto ISO.
However there is a caveat in that if the camera gets to your maximum ISO range and its still not enough to get an accurate exposure then it will automatically drop your shutter speed below your minimum set value.

Ah - that last bit isn't ideal is it. The reason for a minimum shutter speed is that you don't want to drop below that surely! :)

Don't mind using auto ISO though so I'll keep trying to find it in the menu and give it a shot.

Menu 3 - ISO speed settings - minimum shutter speed

Yeah the auto ISO scenario isn't foolproof unless you are working with a huge ISO range to start with. Im guessing shutter priority is out of the question as you want to control your depth of field?

Whats the scenario that you wish to have minimum shutter?

Great, thanks - never would have thought it'd be under the ISO menu!

Nah shutter priority isn't an option really. I'm finding at weddings I'm missing a few moments here and there just due to adjusting settings in manual. It's only a matter of seconds but for reportage/documentary it can make all the difference. I really just want to be able to float between 1.4 and about 2.8 without having to fiddle with anything else.

It's assumed that if you're in Av mode you value the fixed aperture value above everything else. If the shutter speed was absolutely that important you'd be in Tv mode. Once the camera runs out of ISO and you've got the aperture fixed, the only variable it has left to prevent under-exposure is the shutter speed. It's a perfectly sensible and logical step in the programming.

What would you rather it do?
  • under-expose; or
  • prevent you taking the shot; or
  • bump the shutter-speed below the soft-floor set in auto-ISO
 
The problem with TV mode is that the camera might choose too wide an aperture.

I haven't been a Canon user for some time now but with my non Canon cameras I use aperture priority until the shutter speed drops too low and then switch to manual mode and set both the aperture and shutter speed. I've no idea if the Canon allows the use of auto ISO in manual mode but even if it doesn't maybe manual mode with shutter and aperture set is the answer and manually adjust ISO as needed.

Ideally I think you should have the option of some, if not all, of the above. I'd rather have an under-exposed sharp file that I can pull back in Lightroom than a perfectly exposed shot with an insufficient shutter speed. An ideal compromise, I think, would be to give the user an option between allowing the camera to override, adjust and lower the shutter speed and having the option to prevent that happening. A 'hard floor' if you will.
 
just a thought that you might already have tried is manual with unlimeited auto-ISO. That way yoru can set a reasonable shuter speed and forget about it.

This is how I operate, aperture priority (mostly between 1.4-2.8) min shutter of 1/250th most of the time, if I'm reaching ISO 12,800 (rarely!) then I'll drop the shutter speed in the menu to 1/180th or so (dependant on what lens I'm using). I could never use manual at a wedding where you have to be ready to shoot. This will get me a shot within a stop either way of how I want it, which I can then use exposure comp if still in that setting or fix in post.

What's wrong with using Auto ISO in Manual mode? Set the aperture you want, set the shutter speed you want, camera takes care of the ISO, job done. Presumably I'm missing something, but I'm not sure what it is...

This - my cameras are rarely out of this configuration these days unless I have complete control of lighting. Makes sense to me to automate the one part of the exposure triangle which can be tweaked (mostly!) later, and manually control the two that you can't fix in post no matter how fancy your editing gizmo.

Because that leaves two variable (camera wise to think about) when I'd rather just worry about one. I can then concentrate on the 'action'

No exp comp?

You can use exposure compensation in Manual mode. Or at least I can on the 7D Mk II which I use most of the time; I've forgotten which camera you're using these days. ;) It does require me to take my finger off the shutter button, so it's not quite as quick and convenient as setting EC whilst in Av or Tv mode, but I don't have to take the camera away from my eye so it's not hugely inconvenient. I find I can live with it.

I was responding to the poster who has a 6d.
Where there's no function for it :(
 
I think I've missed something? Why not use AV mode if the aperture is the priority, and just adjust the ISO to suit the desired shutter speed? Minimal adjustments required, and little tweaks can still be made with exposure comp too if needed?

Because it's still an adjustment that may take time., AUTO ISO will do the work for me and achieve the same result.

IMO, manual mode (for events) is overrated.

But for the OP?

And it won't achieve the same result if it's creating issues?

Yup, this. The fewer things to fiddle with the better. Even one extra adjustment can mean the difference between getting the shot and just missing it.

On a completely unrelated note - it's funny how some people will have you believe that you're not a proper photographer unless you shoot in full manual. I often see that rhetoric spouted to folk who are still learning or just starting out. That top dial spins for a reason - it's all about choosing the right mode for the right situations.

But you're never going to be able to do this leaving it completely on one setting without adjustment.

AV, auto ISO, with a minimum shutter of 250th means that I've just got to adjust the aperture to suit the situation and click away.

Just to clarify I haven't even tried this method out yet - this is just me thinking out loud.

Edit: the idea is to use the above settings for 90% of the day (reportage) and switch to manual for the remaining 10% (portraits etc) where I can fiddle until my heart's content without fear of missing anything.

More or less what I do.

All flash work in M, I even do all posed stuff w/o flash in AV
