Why does my camera say "Lens not attached" or unrecognized ?

This is a full manual focus lens, no electric contacts, your camera will not detect the lens when mounted, pls switch camera to M mode to work

Why I can't press the shutter button when lens mounted ?

Normally switch your camera to M mode will solve this issue, for some cameras, you need to setting "Release W/O Lens " to Enable on camera menu to make lens work.

Why does my picture out of focus and very blurry ?

Pls rotate the focus ring on the front body of the lens until the subject is in focus , and focus with live-view to achieve accurate focus. Recommend use with a tripod and remote to keep image stable avoid blurry.

Why doesn't the camera display the aperture value?

Because this is a fully manual telephoto lens without electronic communication with the camera body, where the aperture varies with the focal length. Therefore, the camera body typically cannot display the aperture value.
