Thanks for the response!
I typically shoot my 18-135 STM lens, as I only have that and a zoom lens. The Aperature setting is usually at 2.5 or so, which is about as open as it can go... but sometimes it seems to get "stuck" at 3.5 on it's own... not sure how that works
I'm still learning my way around the camera, but I love it so far, and the only way to learn is to read and ask questions!
Thanks again!
Any help is always appreciated!


The camera can only open the aperture of the lens as far as the lens allows. The 18-135 lens starts at 3.5 aperture at wide focal lengths. As the focal length increases, the max aperture changes in a few steps up to 5.6. So if you set it to 3.5 when at 18mm, and zoom in, the camera will correctly display aperture of 5.6 which is the lowest for that focal length. You can't ever set the aperture to anything below the minimum for the focal length you are at.
