It was originally modified for EF-mount, but it was changed for F-mount, which also can be used for EOS_5D too.
How to? See > http://www.pbase.com/kkawakami/top_level_contax_g_sonner_90mm_modification
Actually the lens body has shortened to M42->M42 helicoid(11~18mm) + M42->F adapter. range = 1.3m ~ infinity

For normal portraiture distance @f2.8
At close distance 0.45m @f22, using double helicoids (11~18mm + 16~26mm)
