Your new Catadioptric or Reflex mirror lens is a highly developed, computer designed product which uses 

the merits of both reflex optics and refraction optics. This gives you very sharp picture quality with less color 

aberration, which is considered the most harmful factor in the field of telephoto photography.

A proper T-Mount adapter should be threaded onto the back of your lens in order to attach your lens to your 

camera.

The T-Mount is similar in design to the mount of standard lenses designed for your camera, and is coupled 

and removed in the same manner.  To mount the lens, attach the T-mount adapter to your camera and then 

simply attach the lens to the adapter.

Focusing is accomplished while viewing the subject through the viewfinder of your camera and rotating the 

focusing ring.  Since the aperture is preset, you will find under certain light conditions a shadow appearance 

on the split-image section of your focusing screen.  In this case, simply focus on the edges of your subject 

with the outer center of your prism.
