Wow...
It's the shutter speed that usually kills me with the digital cams... but you've sure seemed to nail it.
Some photographers I use have digital cams but they're $1000's...
But if you can get shots like these with a consumer-type version, then no doubt - they're viable enuff.
Film will never be completely dead though, I doubt. It may be a pain in the ass, but there's something about it...
