Here is didjeridoo_tom's Sony NEX-5 cinema setup. He is using a Hasselblad 50mm f/2.8 Distagon with floating lens elements via a Hasselblad to EOS lens adapter, then an EOS to NEX E-mount lens adapter. The display of the NEX-5 is produced on the Sony CLMV55 portable 5" monitor via an HDMI cable.
The Hasselblad 50mm Distagon FE provides excellent color correction close up and wide open. It was also the preferred lens for NASA space missions.
Check out the photos of didjeridoo_tom's NEX-5 with the Distagon T* 2.8/50 FE and samples from the combination.
