Can I use my HC/HCD lenses with the X1D?
Yes, with the optional X-H adapter. Functionality will vary depending on the lens. The HC/HCD lens must be running firmware version 18.0.0 or later. Additionally, the type of gear box inside of the lens will affect the AF performance. All lenses will offer focus feed back on the rear display or EVF while manual focusing. Contact your subsidiary or ASM or further details.
A firmware update for HC/HCD will be available in the future to allow Autofocus.
