INSTRUCTIONS

Mounting the Lens

Mounting and Detaching the Lens Hood

Remove the lens rear cap. Align the mounting index⑨on your lens 
with the matching mounting index mark on the camera. Insert the 
lens into the camera and turn the lens in the attachment direction 
until it locks with a “click”. Do not apply too much force in case of 
damage to the mount.

Keep the lens hood mounting index②and the mounting dot on the 

camera aligned, and turn the lens hood clockwise until it clicks into 

place.

For the need of detaching the lens hood, please turn the lens hood 

in the direction opposite to that for attaching.

The lens hood helps reduce lens flare and protects the lens front 

element from damage.

Lens hood may be unable to be attached if some certain filters 

have been used with the lens.

If not using the lens hood, you can also place it backwards over the 

lens.

When shooting with a flash, the lens hood may block light, which 

may cause vignetting. So when shooting with camera’s built-in 

flash or with the external flash unit that is not high enough, please 

remove the lens hood first before shooting.

Turn on the "lens-free shutter release" function in the camera, as it is a 

non-CPU lens, data information cannot be provided.

Detaching the Lens

Turn the camera off and press the lens release button on the 
camera, turn the lens in the direction opposite to that for attaching, 
and pull it out.
Gently turn the lens back and forth to ensure that the lens is fully 
attached to the camera.
