Manufacturer’s product description:
The Omegon T-2 Adapter for Canon EOS Cameras allows you to adapt all Canon EOS cameras to the standard T-2 thread.
A T2 adapter is required for connecting SLR or DSLR cameras to other adapters such as projection adapters, focal adapters, off-axis guiders, etc. This T2 adapter has the correct bayonet fitting for the camera concerned and connects via the universal M42x0.75 T2 connecting thread.
Once you have attached the T-2 ring to your camera, you will find the T-2 internal thread on the open connection side. Now you simply select the correct part for the required connection from our range of adapters.
