Get set

set Up your spyderLenscal

Unlock the SpyderLensCal and place the ruler in the correct

orientation with the main target. Use the tripod mount if

desired. The bubble indicator will let you level the tripod

for most effective alignment with the camera. You can also

place the SpyderLensCal on a desk, table or shelf.

set Up your camera

Select the camera and lenses you want to calibrate

and set them to autofocus with the stabilizing function

off. Make sure you're in Aperture Priority or Manual

mode. Your camera should be set to the widest aperture

(lowest number) on the lens with an ISO 200 setting.

Maximize the camera's contrast and sharpness settings

to make the readings of the SpyderLensCal easy to see.

set the distance

To calibrate your lenses, it is recommended that you

make the distance from the camera to the SpyderLensCal

the same distance at which you normally shoot images

with each lens. The SpyderLensCal and your camera

should always be in parallel positions, at the same height,

with the front of the lens parallel to the front target face

of the SpyderLensCal. See the illustrations at right for

correct positioning.

shooting environment

Choose a location with appropriate lighting. Be sure

the environment is not too dark, and does not have too

much uncontrolled light directly behind the camera.

Light emanating from other angles in front of the target

location from one or more sources is acceptable.

A studio shoot set up, while optimal, is not necessary.

Optimal Distance = Distance Frequently Used /

Focal Length x 30~50 times e.g. 35mm x 30~50 = 105~175cm
