Recommended cameras and lenses
 Using lenses that extend and retreat during AF operation
Nikkor lenses that extend and retreat in length during AF operation may not
autofocus correctly, or may lead to damage of the lens or camera's autofocus
mechanism due to the weight of the flash head. Therefore, do not perform
autofocus operation, but use manual focus instead.
 Using an AF Micro-Nikkor 60mm f/2.8D lens
• Be sure to attach the Dedicated Adapter Ring UR-5 (optional) to the AF Micro-Nikkor
60mm f/2.8D lens, then attach the SX-1 to the lens with the Adapter Ring SY-1-72.

Autofocus operation is possible if you attach the Attachment Ring SX-1 to the AF Micro-
Nikkor 105mm f/2.8D lens using the Adapter Ring SY-1-62.
