Help, 7D issues

[TheNissanMan]

I'm sure it's something I've accidentally hit but when in manual mode on my 7D I now don't appear to have f/7.1 with a 100-400 attached, am assuming its the same with other lenses.

Can anyone think which setting it would be?

Have you checked whether you get f6.3, f13 or any of the other 1/3 stop f-numbers? If not then either the 7D doesn't allow 1/3 stops in manual mode or you've disabled the custom function in the menu - sorry don't have my 7D to hand to check.

Thanks brach, did a google and found it. Your spot on, I inadvertently change the custom exposure setting to 1/2 stop so sorted
