A Dome Port is used commonly with wide angle and fisheye lenses, typically 8mm
at the shortest (35mm equivalent) to about 20-35mm.
Referring to the image, setup the SPR’s so the end of the lens – either the lens
body or glass element – extends slightly into the port.
Test for vignetting and image quality. If necessary adjust the position of the lens
with respect to the port and re-test to achieve optimum results.

CAUTION! CAREFULLY INSTALL DOME PORT AND OBSERVE POSSIBLE
INTEFERENCE WITH GLASS DOME.
