Baader T-Ring to connect Sony E/NEX DSLR cameras on the Astro T-2 system
All Baader Wide-T-rings have an S52 dovetail in addition to the inserted T-2 ring. This allows the T-ring to be modified to an M48 female thread using the S52 / M48 adapter #2958552, or to use the S52 barrel #2958551 without the T-2 reduction. With the S52 / M68 adapter # 2458252, the Wide-T-Ring can be directly attached to an M68 male thread to securely fasten your camera to the widest possible aperture.
All Baader Wide T-rings can be directly adapted to an UFC (Universal Filter Changer) with the optional Baader UFC S52 dovetail camera-adapter (#2459119), in order to change different filter sizes directly in front of the camera sensor.
With the ultra-short Backfocus of only 26.3mm (18mm camera, 8.3mm T-2 bayonet ring) many adaptations in combination with reducers / filter wheels are now possible for the first time. Furthermore, the illumination of the camera chips improved significantly, mainly because of the larger clear aperture.
