TS Canon EOS T2-Adapter with Filter Quick Changer - Low Profile

The TS Optics filter drawer for EOS DSLR cameras is both a T2 ring and filter drawer. You can use your DSLR camera like before but you now have the option to add a full size filter without altering the back focus.

The filter can be exchanged without touching the camera!

Fields of use in astro photography

If the camera´s original IR cut filter has been removed, a separate IR filter can be used
♦ You can insert contrast enhancing filters like UHC, Deep Sky, Nebula filters
♦ Enhanced RGB imaging is possible by using narrow-band color filters (see accessories)

Adaptation to correctors and telescopes by T2 thread

At the telescope side, the filter drawer has a female T2 thread. With the optical length of 9 mm plus 1 mm for the steel spacer, the same length as a standard T2 connection is possible.

Many correctors have a relatively long T2-thread that may intrude the filter drawer and possible cause problems with the filter change. Here, we used the 1mm spacer to prevent this problem.

Which unmounted filters can be used?

We offer two drawers for the filter changer: one for 36 mm filters and one for 50 / 50.4 mm filters. For APS-C cameras, 36 mm filters are sufficient so the smaller TSFES36 can be used. For full-size DSLR sensors, we recommend the TSFES50. Both are listed in the accessories section.
