PERCAUTIONS

FEATURES

Do not disassemble or modify the lens by yourself. If it is damaged 
by external force, do not touch any exposed part of the lens. 

Do not expose the lens to excessive heat such as direct sunshine or 
a parked car as this may deform the glass elements. 

When it is not attached to the camera, do not leave the lens under 
the sun without the lens cap attached. This is to prevent the lens 
from concentrating the sun’s rays, which may cause a fire. 

When shooting with the built-in flash of the camera, the lens itself 
may block light and cause light fall-off. So external flash can be 
recommended in such case. 

Safety Precautions

Compact body and ease of use make the lens a perfect match for 
macro photography with great stability. 

For easy lighting setup, the lens is able to allow extremely long 
working  distance  ranging  from  40mm  (5X)  to  45mm  (2.5X) 
through special optical design. 

Full-metal construction makes the lens feel really solid with great 
durability.  Multi-layer  anti-reflection  coating  for  each  glass 
element contributes to minimizing flare and ghost. 

LAOWA LW-FF 25mmf/2.8 2.5-5.0X is a high-magnification full frame 
ultra macro lens that can magnify the subject from 2.5X to 5X.
