I have never really gotten into it and I made some changes using C1-3 modes. I prefer to shoot with ISO at 1/1. I see that Auto ISO overrides 1/1. Just wanted to be sure I'm not missing something. I can't find anything on the manual about this.

Thanks in advance.

What does ISO at 1/1 mean?

Can you clarify a bit more? When you say you prefer to shoot ISO at 1:1, you mean you'd want it to always be ISO 400 at shutter speed 1/400?

Auto ISO is just like Av or Tv in that it adjusts the specific property to the camera's liking for the light it's seeing...not to a particular setting. So, you can't really get to that combination, reliably, with auto anything set.

If you have one of the newer bodies that allows EC along with Auto ISO, you might be able to calculate an approximation setting out, but that isn't even going to be reliable across lighting conditions.

1/1 means 100, 200, 400, 800, 1600, 3200 and so on. Nothing in between. To get those you set it to 1 /3.

No. Just ISO settings at 100, 200, 400, 800, 1600, 3200 and so on.

1/1 means 100, 200, 400, 800, 1600, 3200 and so on. Nothing in between. To get those you set it to 1 /3.

I've been wanting the same thing and just before I saw your post I looked up the 80D manual to see if it can be done. Then I realised that, at least in M mode, you wouldn't be able to get fine (1/3 stop) exposure adjustments, so there's no point, especially if you are bracketing.

The reason I ask and set it to 1/1 is I have LR default settings that auto apply at import. They are based on ISO and cameras serial number and NR adjustments are unique to each ISO. If I went with 1 /3 then it would be a nightmare to manage. I don't miss in the in between ISO values as I'm not afraid of higher ISO. For example I'm OK to go from 800 to 1600.

I checked and believe you are correct. Auto ISO uses 1/3 stops regardless of setting the ISO to 1/1

Verified. My 80D and 6D both work that way. I would find that annoying if I wanted whole-stop ISO settings.

Roll with it. We're all headed that way, if we live long enough. :)

Some of us are looking at it in the rearview mirror :D
