TS Canon EOS M48-adapter with filter quick changer - optical length 9 mm

Suitable for unmounted filter glasses with 36, 50 and 50.4mm diameter

The TS Optics filter drawer for Canon EOS cameras is M48 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!

Astrophotography

• 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

Adaptation to correctors and telescopes through 2" filterthread (M48x0.75)

At the telescope side, the filter drawer has a female M48-thread. With the optical length of 9 mm plus 1 mm for the steel spacer, the same length as a standard M48 ring is achieved.

Many correctors have a relatively long M48-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.
