Baader Wide T-Ring für Sony e-mount E/Nex Bayonet to M48 and T2

Baader T-Ring Sony E/NEX mount to the T2 and the M48 thread.

With the ultra-short backfocus of only 26.3 mm (18 mm camera, 8.3 mm T2/bayonet ring), many adaptations to reducers / filter wheels become possible for the first time. Additionally, the llumination of the camera sensor is improved significantly, due to a larger clear aperture.

The Sony Alpha 7 cameras - in particular 7S and 7SII - are very interesting, due to their high sensitivity, low height and small weight.

For the shortest possible adaption to back-focus sensitive systems like Hyperstar or fast Newtonians, Baader has developed a T-ring for the Sony E-Mount/NEX bayonet which is extremely short and only adds 8.3 mm to the 18 mm back focus of the camera body.

To avoid vignetting, not only a T-thread was implemented, but also M48 and even an S52 connector. Optionally, a 2" barrel (BA2958551) with S52 doevtail ring is available which can directly attached to the S52 receptacle of our e/NEX T-ring.

Due to the large clear aperture of 46 mm, the 2" barrel provides a image field free of vignetting when used with the SONY Alpha 7 cameras.
