One of the things I missed most about moving from my old point and shoot to my Nikon D80 DSLR when I first did it was the lack of video recording on the D80. Once the D90 hit video recording was featured again.
Apparently, many people are now making movies with DSLRs that record HD video and famous optics firm Carl Zeiss have unveiled the first cine lenses for HDDSLR cameras. The new lenses include the Compact Prime CP.2 lens that works with cameras like the Canon 5D Mark II. The lens has interchangeable mounts for future upgrades and come in focal lengths form 18mm to 85mm.
The firm has also debuted new Lightweight Zoom LWZ.2 lenses that work with the PL, EF, and F mounts on most all video enabled cameras. Neither of the lenses has a price fixed to them yet, but they will be expensive. Both lenses are set to land in June.
