This Vid was shot on the "Carl Zeiss 50mm Planar T 1.4 for Contax". It´s an extremely good lens from Carl Zeiss made for the Contax/Yashica mount. It feels solid and the sheer amount you are able to pull focus is just amazing. It handles like you´d expect from a Zeiss lens. The best part, you can get this lens on ebay for around 200 Euros, which is way less then a Zeiss ZE/ZF lens. The bokeh is just stunning and looks best from f-stop 1.4 to 4.
This vid was shot mostly on f-stop 4 or higher, so the next vid is going to be a night or indoor shoot to show of the bokeh. The only real competitor in price and performance is the the Nikon Ai 50mm 1.4 in my opinion. I like the Zeiss better, due to it´s fabrication and focus handling. With an adapter you can slap this lens in front of any Canon Eos camera. So far I am very happy to get my hands on this baby.
