Manual mode- what does "L" mean?

Mark iii 5D

 

Trying to shoot the supermoon tonight.

In manual mode I tried to start with the sunny f16 basics. I could set iso 100, exposure 1/125, but when I went to f stop which was set at 5.6 and tried to change it it said "L" no matter what I tried.

Any thoughts on what L means and why I couldnt set this to what I wanted if it was in full manual mode?

many thanks

"I tried to start with the sunny f16 basics."

 

You should start with the "Loony 11 Rule."

The basic rule is, 'For astronomical photos of the moon's surface, set aperture to f/11 and shutter speed to the [reciprocal of the] ISO speed.

  • With ISO 100 setting in the camera set the aperture to f/11 and the shutter speed to 1/100 or 1/125 second on some cameras 1/125 second is the closest available setting nearest to 1/100 second.
  • With ISO 200 setting and aperture at f/11, set shutter speed to 1/200 or 1/250.
  • With ISO 400 setting and aperture at f/11, set shutter speed to 1/400 or 1/500.

A lot of Canon stuff. Along with, a lot of other stuff.

It means you have the lock switch engaged under the rear control wheel.
