Canon 80D and 90D minor but nuisance issues

[socal_airshow]

Having some minor issues with both my 80D and 90D bodies. Haven't used them very much, so there could be a bit of 'operator error' factor here.  My 80D has suddenly stopped allowing me to do manual exposure compensation. When I try it when looking thru the viewfinder, an "L" comes up and flashes. My 90D is having three issues - #1, with autofocus selection. Even though I select the area and mode, it they don't seem to stay selected and the camera keeps telling me to choose 'em. Fortunately it's not impacting whether or not the shutter will fire. Just a bit of an nuisance. #2, while scrolling through photos (some of us aviation photogs call it "chimping"), the camera keeps zooming in rapidly on the images - I have no control over it. What the? It's almost like the button you press to zoom in on em, is acting like it's stuck, but it doesn't look stuck. And #3, a flashing red light - presumably the same one you'd see as the camera is writing to the card, never stops flashing when I power up the camera. It only stops when I open the sd card door.  Another "what the?". 

Any thoughts? Thanks.

Hello socal_airshow I would check to see if the lock switch isn't enabled on the back of the camera. If it is "L" will flash in the viewfinder.

yep, that did it. Thanks for the info!

If the red light keeps flashing, it means that is writing to the card. I suggest you either replace the card or format it in the camera.You can lose data if the door is opened while the light is flashing.

Also, what shooting mode are you in? You cannot set exposure compensation in Manual mode.

I think Demetrius nailed it.  The [LOCK] switch may be the culprit.

You can set EC when in Manual mode provided you have ISO set to Auto.  I think of this configuration as Ev, mode, Esposure Priority.  Dialing in EC directly impacts the ISO.

thanks. Yes he got it. I checked the camera and sure enough that was it. Thanks!

I'm almost always in Shutter Priority or Aperture Priority mode.  On my 90D the red light shuts off like it should, however on my 80D it never stops, even if I've only turned the camera on and have not shot a frame.

And now you have corrected me. We are even. 8^)
