I JUST GOT MY LETUS!!!!!!!!!!
I found used nikon lenses online and they look great.
Nikon 35mm 1.4
Nikon 50mm 1.4
Nikon 85mm 2
I intentionally go the letus with the 82mm ring even though my camera takes a 72mm. I did this because I won't have my DVX forever and my next camera will probably be an HVX200 or the 170 by panasonic. I also got it because the 72-82 step up ring was a lot less than buying the additional letus ring. (Yes, I am a cheap skate, thanks for asking.)
But I do know where to spend money! I knew the letus weighted a lot so I got Zacuto rails to support all the weight. These will come in handy when I do sports shoots as well as the usual "not exactly safe" stuff.
I'm helping a buddy of mine shoot he senior thesis tomorrow with the camera. I'll see if I can post the results here for you guys to see.
