T2 Adapter Ring for Pentax K / Sigma SA Cameras

T2 Adapter Ring for Pentax K / Sigma SA Cameras

DESCRIPTION

The T2 adapter ring is designed to connect a Pentax K or Sigma SA DSLR to a standard T2 thread (M42 x 0.75 mm). This mechanical interface enables the secure attachment of the camera to any accessory or telescope using a T2 mount. It is particularly suitable for prime focus astrophotography, where the telescope serves as the camera lens. The ring ensures proper back focus and alignment, allowing sharp imaging. Its mechanical thickness is optimized to maintain the correct flange distance for these mounts.
