How to use our manual lenses on your cameras

a. Set the mode dial to Manual (M).

b. Set the Release w/o Lens option in the camera menu to Enable.

1. Select → MENU → Custom Settings → Release w/o Lens → Enable.
2. Set the Shutter lock option, if available, in the camera menu to Off: no lens.

For most dslr cameras, setting the "Dial" to M mode will enable the ability to use lens manually, however, some mirrorless cameras might require a further step---setting shutter lock option to Off: no lens.
