I've got one. Its most excellent. I've read about people having issues with focus, but .. I don't have them. You'll just have to mess around with it for a while. But go for it man. I love the images it produces. Supposedly you can shoot squeeze mode, and stretch the video out even more for a cinema-scope aspect ratio at the loss of vertical/horizonal resolution. I might give it a shot and see what it looks like.
Check out my post in the dvx100 videos/screen cap's called "PSA shot in 24pa anamorphic."
Also; if you see dust in it you'll definately want to get it cleaned. When I got mine it came from japan and it had dust on the inside of the lense. And don't lose that lense cap, its a calibration utility as well!
