Canon EOS Framing T-2 Adapter

Weight: lbs
!
Exlcusive from STI for Canon EOS DSLRs

This specially designed T-2 adapter for Canon EOS cameras is a true time saver. It adds easy framing flexibility not found in a regular t-ring.   By simply unloosening the locking screw, the entire camera can be easily rotated and repositioned in order to assure your image is framed exactly as you want it to be.  Like a normal t-ring, it may be mounted to any standard t-threaded accessory such as a t-adapter, 2" nosepiece, 1.25" nosepiece, OAG, etc.  An exclusive hand-tuned ball-bearing mount guarantees minimal loss in axial positioning of the image throughout 360 degree rotation.  Holds up to 20lbs.

(Note: Attach your camera and frame your object first, and then retrain your scope, if necessary, on a brighter object to focus. This avoids any axial movement due to thermal expansion.)

C-mount adapters allow you to use regular 35mm camera lenses on accessories that have a female c-mount thread.  Most quality camcorders and video cameras have removeable lenses that are held in place with a c-mount thread.  If your lens can be unscrewed, most likely it uses a c-mount.  In use, screw the c-mount adapter into your video camera, and then attach your camera lens to the adapter normally.
