231Technical Notes FTZ Mount Adapter User’s Manual
Using the Mount Adapter
Autofocus may not function as expected when the adapter is
used with an F mount NIKKOR lens. If the camera has trouble
focusing, set the AF-area mode to single point and select the
center focus area, or focus manually.
With some lenses, the camera vibration reduction feature may
not function as expected or may cause vignetting or a drop in
peripheral illumination.
Precautions for Use
When using the adapter with lenses weighing over 1300 g (2 lb
13.9 oz), support the lens when holding the camera and do not
use the camera strap. Failure to observe these precautions
could damage the camera lens mount.
When using telephoto lenses equipped with a tripod collar,
attach the tripod to the lens tripod collar rather than to the
adapter tripod socket.
Keep the CPU and lens signal contacts clean.
Keep the adapter dry. Rusting of the internal mechanism can
cause irreparable damage.
Leaving the adapter in extremely hot locations could damage
or warp parts made from reinforced plastic.
