Geoptik variable distance ring 7,4-9,5mm for CCD lens adapter
Geoptik variable T2 distance from 7.4 to 9.5mm for CCD lens adapter
Allows adjustment of the exact distance between camera and lens
For lenses shorter than 200mm focal length, the exact distance between camera and lens matters. The shorter the focal length of the lens, the more precise the distance must be. Deviations of 1/10mm are already clearly visible. The variable T2 distance makes it possible to set the distance with an accuracy of up to approx. 1/20mm.
It fits directly on the adapters 30A189 for Canon EOS lenses and 30A191 for NIKON lenses. You can set the distance very accurately with this adapter and the TS T2 extensions with 5mm and 10mm (for cameras with very little backfocus distance).
