Pulling my hair out! Canon 90D (1 Viewer)

[John In Ireland]

Ok so I set to Manual mode. I set my exposure to 1/1000. Fine. Next time I shoot the exposure time has altered??? It is always dropping to a longer exposure and not always the same value. So I have to check to see if my exposure has altered before taking the next shot??? Any ideas?

What happens in between shots? The dials on Canon cameras are generally vulnerable to being knocked if on a sling or put into/taken out of soft bags. Check your settings as a matter of course is the only real solution.

i constantley have to check aperture settings on my 7dmk2 as the wheel is moved easily whilst out and about

I have not long been using manual mode long. In AV or TV I don't have a problem. Strange????

It seems to be. Try a firmware update?

Have you altered the exposure compensation (red menu) without realising?

My exposure comp at red 2 is set at zero. ☹️

Is 'Safety Shift' enabled in the custom settings? If so, turn it off.

Excuse my ignorance. Can't find the safety shift. Where would it be in the menu?

Safety Shift info is on page 558 of the advanced user guide

Thanks for this. Much appreciated. Does this apply to Manual mode as well?

To be honest, I don't think it does. For odd exposure behaviour it's always worth checking but it's probably not your problem in this case.
