That's an old post but I thought to contribute.
I have the Samyang 135mm T2.2 and it performs perfectly on my modified Canon 6D.

Preserving Autofocus on Modded DSLR's

This is an old thread but I believe I can contribute. I have converted over 200 Canon and Nikon cameras for astrophotography and IR.
The greatest danger is sensor tilt. In cameras with torx screws and springs, if one screw is misaligned you get sensor tilt, meaning stars will not focus correctly from one side.
A safe approach for astro or full spectrum clear glass conversions: Mark the exact screw positions with a thin marker. Count screw turns so you can return at the exact same position. Measure internal filter thickness and replace them with an equally thick filter or clear glass.
The safest approach: Contact me and I can do it for you. 🙂
