I thought, in relation to the XHA1 projects discussion, that I would mention The Signal, a feature that was shot, I believe, not with the Canon XHA1 but with the XLH1. However, the two cameras utilize extremely similar systems and the same chip, the primary difference being only the interchangeable lenses of the XLH1. In many forum discussions, people almost use the two cameras interchangeably...
The project has met with some notable recognition and is considered one of the success stories of the Canon prosumer line.
Indeed, in terms of narrative cinematic work, it may be the Canon prosumer line's high water mark in terms of cinematic feel, film look and effective storytelling.
