Precautions

 

 

Lens uses a supersonic motor. When the lens is

 

mounted on a camera body that does not support

DA17-70mm f/4 AL [IF] SDM

supersonic motors (including

with

firmware older than version 1.30), the autofocus

 

 

cannot be operated by either the AF motor in the

 

camera body or the supersonic motor.

 

DA 16-50mm f/2.8ED AL [IF] SDM

When the lens is mounted on a camera body that

DA 50-135mm f/2.8ED [IF] SDM

does not support supersonic motors (including

DA 200mm f/2.8ED [IF] SDM

with firmware older than version 1.30), the

DA 300mm f/4ED [IF] SDM

autofocus is operated by the AF motor in the camera

 

body.

 

* In both cases focusing can be done manually.
