Rokinon 35mm cine lens

Hi, I have a Canon Rebel t6i and just bought the rokinon 35mm lens. It’s a manual adjust. When I attached it to the camera and went to apurture priority mode and when I was trying to change the apature, it said no lens detected. I don’t know what I’m doing wrong or if it’s because it’s a manual lens.

It is a manual lens, which mean it does not communicate with the camera’s autofocus and aperture control firmware.

Some cameras have a menu setting that prevents the shutter from firing with no lens attached.

Because a fully manual lens has not communication with the camera body, the camera cannot tell the difference between no lens attached, and a fully manual lens has been attached.

I always use M mode with fully manual lenses. I also dial an aperture value to the aperture setting on the lens, which seems to help the camera to meter the exposure correctly.

"It’s a manual adjust."

A lot of folks seem to not understand that this means, you do everything. Try sitting the camera to M mode.
