I just purchased a Sony DSC-M2. While the camera does take great video and stills in lighted rooms/environments, the video quality is terrible in low light conditions. I tend to go out with my friends to lounges/bars/clubs and wanted a hybrid to take along. This one will never work.
I was reading that the Sanyo VPC-C6 is better in low light, although I am a bit skeptical as to how well it will perform. I do not think there is any night vision, but I am not sure.
If this will not work, are there any hybrids out there that would do the job? Or can I get an attachment that would provide the night vision?
