The Baader Wide-T-Ring allows the connection of Sony E/NEX mount to the M48 thread and T2 (M42) through 2 separate internal rings.

With the ultra-short backfocus of only 26.3mm (18 mm camera, 8.3 mm T2/bayonet ring), Sony cameras are very versatile and can be used in systems with reduced back focus. Also, the illumination 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 dimensions and small weight.

Differently from the other Baader T-Wide camera adapters, this model for Sony E-mount E/NEX includes two separate rings; one with M42 female thread and another with M48 female thread.

Also, the ring can be replaced with various other connections (sold separately):

• 2" adapter with M48 x 0.75 filter thread. With adapter # 2958551 you can attach the Wide-T-Ring directly to the 2" without the T2 bottleneck. The M48 x 0.75 thread on the other side of this adapter allows to screw standard 2" filters.
  

• Connection to the M68 x 1 (Zeiss type) thread. With adapter # 2458252 you can attach the Wide-T-Ring directly to focusers and adapters with the female M68 x 1 thread.

• Connection to the Baader UFC Filter Chamber System. With adapter # 2459119 you can attach the Wide-T-Ring directly to the Baader UFC (Universal Filter Changer) System.
