The photographic adapter allows you to take photos of microscope slides (digital or traditional). The adapter is placed in the microscope tube instead of the eyepiece, and the threaded part allows you to attach the T2 ring appropriate for your camera (eg Canon EOS, Minolta AF, Sony, Nikon, Pentax K, Pentax S, Sony NEX, Micro 4/3 etc.).
A set of photographic adapter + T2 adapter ring allows you to connect any camera with a detachable lens to the microscope.
The short profile of the adapter ensures very good rigidity of the connection between the microscope and the camera.
