Right now the digital rotating cameras are either expensive or extremely expensive. I drool over the new roundshot digital, but am quite happy to shoot with my cirkuts for b&W and roundshots for color. I only wonder how long 70mm color film will be around. On rotating cameras, keep an eye out for ebay deals. They come up often enough. Rotating camera photography is lot's of fun. I've been addicted for years now. I wouldn't be surprised if someone came out with a digi swing lense at some point.
