Threads onto VC200L focal reducer or the VC200L 60mm draw tube or R200SS Coma Corrector #3746
Includes the optional outer ring #3765 (Canon EOS T-ring).
Once mounted you can easily rotate the camera body and lock it securely in place using 3 thumbscrews to aide composition.
This wide adaptor has less vignetting than standard Canon EOS T adaptors and attaches securely with threads to stop Flex.
Works well with VC200L reducer in my other advert.
