TS-Optics T2 counter ring for exact distance determination - thickness 1.5 mm
With the safety ring TS T2 you can set exact distances. The spacer ring is very thin (only 1.5mm) and has a T2 female thread.
This is how you do it:
Thread lock ring T2 onto male thread T2. Then turn the connecting piece (camera, adapter...) over the thread until optimal sharpness is achieved. Then lock the position with the lock ring by turning it against the connecting piece. The ribbed exterior of the ring makes it easier.
Optimal use with the following parts:
♦ T2 extension rings
♦ Radial Guides and TSOAG27
♦ TS T2i-T2i adapter - continuous internal thread
♦ TS adapter T2a-T2a - continuous external thread T2
With the adapter "T2i-T2i", the adapter "T2a-T2a" and the T2 locking ring, you can make an ultra-short T2 extension with a variable length, very useful, for example, when fine-tuning the focus positions for off . -axis guidance, the focus of the guidance camera on the off-axis guider or the optimal adaptation to focal length reducers.
