TS Canon EOS T-Adapter with filter quick changer - 9 mm optical lengthSuitable for unmounted filter glasses with 36, 50 and 50.4mm diameter
The TS Optics filter drawer for Canon EOS cameras is T2 ring and filter drawer in one. 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!
Adaptation to correctors and T2 lenses (M42x0.75)
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
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 ring is achieved.
Many correctors have a relatively long T-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.
Suitable unmounted filters
Two drawers are offered for the filter changer: one for 36mm filters and one for 50 / 50.4 mm filters. For APS-C cameras, 36mm filters are sufficient so the smaller TSO-TSFES36 can be used. For full size DSLR sensors, we recommend the TSO-TSFES50.
