Directions for Use (Fig. 1-5)
Fig 1. The device is ready to be used with Nikon SLR cameras. For
use with Canon cameras, detach the installed F-MOUNT adapter and
replace it with the EF-EF-S adapter, making sure the alignment pin
(AP) is seated in its mating hole.
Carefully place the device with the faceplate (FP) onto the skin. Fig.
2: To activate the unit in polarized mode, push on the X button. To
activate non-polarized illumination, push it again. You may change the
eld-of-view by rotating the zoom ring (ZR) to either the fully zoomed-
in or zoomed-out position; avoid a midrange zoom setting as this may
result in out-of-focus images. The numbers on the zoom ring indicate
image frame height in mm for both full-frame sensors as well as cam-
eras with a smaller sensor size.
The device captures images with a very shallow depth of eld which
enables precise focusing on the area of interest. The focus ring’s (FR)
“0” mark has been factory-calibrated to result in sharp images in most
cases. To make ne focus adjustments, activate the “Live View” mode
on your camera, if available, then digitally zoom in using your camera
controls while turning the focus ring (FR) one marking to the right or
left.
Fig. 3: By attaching the ash sync cable (FC) as shown, the device will
automatically change polarization mode after each photo.
Fig. 4. Zoom lock (ZL): In order to achieve repeatability, you may lock
the zoom ring using the included hex key. Simply remove the adapter
ring (AR), turn the key as shown, then reattach the ring.
Fig. 5 The spacer (SP) and faceplate (FP) are attached magnetically
and may be easily removed for cleaning. To turn o the unit, push and
