I'm looking for a camera that will take still images while still recording video. Anything I've found has to switch to a "stills" or "screen shot" mode, thus disabling the video recording. It is for use during sterile surgery and we want to record the whole procedure and take stills as and when necessary. Stopping and starting video to take stills is not ideal. Preferably, it should have a remote to take the still images but not essential. Any ideas greatly appreciated. Thankies.
