Checking and Adjusting Auto Focus 

 
After you have set up the SpyderLENSCAL and your camera as instructed above, you are 
ready to check and adjust your auto focus. 

Look through your camera’s viewfinder and 

select the center auto focus point. Adjust your camera until the center auto focus point 
is positioned over the small, concentric squares on the right edge of the SpyderLENSCAL 
target next to the 

0

 on the ruler guide. Focus and capture an image. It is advisable to 

use the self-timer or a cable release so you do not introduce any vibration during 
capture. (Do not use live view to focus and capture the image of the target or use a 
focus-and-recompose method)
