I took some shots this morning and when I reviewed them later I noticed very high shutter speeds and lots of noise. This was because the ISO had been set to 25600, but I didn't do it - at least not deliberately. I've only had the camera a couple of weeks and it is the second time this has happened. I ignored it the first time, thinking that it must have been me, but now it has happened a second time I'm not so sure.
I very rarely set the ISO to a specified value and normally always leave it on Auto ISO. Even when I do set the ISO manually, I never use 25600. I certainly didn't change the ISO setting via the menu and I can't see how I might have accidentally changed it by inadvertently pressing the ISO button on the rear. In addition to pressing the button it is also necessary to turn the dial in order to change the ISO setting. Anyway, in case this is the problem I have now reassigned the ISO button to another function so that the ISO value cannot be changed by using external controls.
The shots this morning weren't important (just more test shots for the EF-M 55-200mm) and I can easily go back and take the shots again, but in other circumstances I might have been a bit upset because at 25600 they aren't that usable.
With the original EOS M I sometimes twisted the dial at the top accidentally as I took the camera from its case and put the camera into movie mode from still mode, but this was definitely my error. With the problem on the M6 I really can't figure out how I could have done it accidentally.
I've done a quick search on Google and can't find any other instances of this problem, so perhaps it is me. I've now made a mental note to check the camera settings every time before I start using it and not simply to assume that the settings were the same as the last session. I can't replicate the problem at will. The camera firmware version is 1.0.0.
Apart from having to remember to check the settings frequently it's not a major issue, but I was wondering whether anyone had seen this or had any ideas what I might be doing.
Any thoughts?
