Thank you! Finally, I found out how to change it! I have a Canon 90d and for almost the time have been using my camera with a viewfinder also it needs to be unlocked to be able to change the aperture. Thanks

I need helpppp my lens should be able to go down to f3.6 but it won’t let me go lower then f5.6 which is highest my lens is supposed to go and I can’t figure out how to change it

Do you know how to fix the Lens Not Attached message? When I try to change aperture, I have an f00 showing and it says I cannot change aperture due to the lens not being attached (but the telephoto lens is attached). I'm searching through all of my menu screens, but cannot find which setting I'm supposed to change. Can anyone please help? Thank you!
