6 Appendix

Aperture Ring Use

When [Using aperture ring] is set to [2 (Permitted)] in [ACustom] menu (p.101), the shutter can be released even if the aperture ring of the D FA, FA, F or A lens is not set to the s position or a lens without a s position is attached. However, the features will be restricted as shown in the table below.

The camera operates in c(Aperture Priority) mode even if the mode dial is at e or b when the aperture is set to a value other than s.
