Hello and a question

[DavidB]

From Cambridge in the UK. I shot film and still do a little bit. My first 'proper' digital was a Nikon D70 and I worked my way through the models to D500 and meanwhile branched out in mirrorless with Fuji. Quite recently I decided to go full frame after looking at ten million photos and deciding that full frame is better for overall image quality. And I wrenched myself away from Nikon to explore Canon colours. Somehow I have always thought of Canon images being more light and airy and Nikon as being more blocked up and contrasty. The proof of the pudding - and I feel I made a good move to a Canon R6.

Now to the question. I generally shoot in AV (Aperture Priority) and I have the focus set to centre square, the front dial to aperture, the rear wheel set to ISO, the spinning wheel set to exposure compensation, ad the asterisk button ( the * ) set to switch focus to human face eye recognition

All is good except when I spin the rear dial down to ISO 100 - sometimes it spins to AUTO ISO and sometimes it doesn't. And I can't figure out what and why it is happening. I wonder whether I am catching one of the buttons on the top back corner with my right thumb but I can't figure it out.

Lenses - the RF 35mm 1.8 ad the RF 85mm f2

Welcome, DavidB. Sorry for an uninformed answer, but... famous last words... can you set the minimum ISO as well as the high ISO? If so, can that remove Auto-ISO from the wheel?

I can't help with your R6, but it is definitely the case that some control methods can access Auto-ISO and some can't. On my R7, I use the control ring for ISO but it will not access Auto. However, if I use M-Fn I can access it. Similar on the R3; M-Fn will do it but ISO on the thumb scroll will not.
