Canon 6d distance from front to chip?

[batema]

Hello,

If anyone could point me in the direction to find this out that would be great. I have bought a William Optics AFR-IV Adjustable Flattener / 0.8x Reducer and am looking at working out the distance from flattener to chip.

Thank you

Mark

44.6mm if my memory serves.

Alex is right, the T-thread adapters are usually engineered such that the total focal length when attached to the camera is 55mm.
