T Mount Adapter Ring Olympus OM (For Film Camera)

This adapter is for the original OM Film camera mount NOT the Micro 4/3 mount. Please see that it has the tab on the bayonet signifying that it is for the old OM mounts. Please read below.

The key difference between OM mount and OM System relates to the shift from film to digital photography and the change in the company itself. The term OM mount refers to the original lens mount used by Olympus on its 35mm film SLR cameras, easily identified by the unique tabs on the lens barrel used for release. This is associated with the original Olympus products and is an obsolete standard. In contrast, OM System (or M4/3) refers to the modern digital standard (Four Thirds and Micro Four Thirds) that Olympus adopted when it moved to digital, and is also the name of the new company, OM Systems, which acquired the camera manufacturing division. Thus, OM mount is the old, film-era standard, while OM System is the new, digital-era standard and the current name of the camera company.

A T-Ring couples your 35mm film camera body to a T-Adapter, off Axis Guider or Tele-Extender. This accessory is required if you want to do any type of photography through a telescope or spotting scope. Each camera manufacturer has a different mount, which requires a specific T-Ring, so CCTS offers a full line of T-Rings.

To use a T-Ring, remove the diagonal and/or eyepiece from your telescope (some models require use of an eyepiece (see your instruction manual). Then you need only remove your normal camera lens, attach the proper T-Ring for your camera, and mount the combination to the rear cell of your telescope or spotting scope with a Camera T-Adapter.
