Re: TM900 and 7D comparison video
Jim,
The 50mm f1.8 is certainly not mechanically on the same plane as the 50mm f1.2, no argument there. It is, however, razor sharp and is used by many as a portrait lens. Just before taking the video samples, I took high resolution photographs. Below are two extreme, extreme, digital zooms of two photographs and you can see they are in very good focus. I've attached screen shots showing the level of zoom used for the digital zoom levels of the photograph with isn't too terribly different from the video samples shown in the video comparison at the beginning of the piece. Certainly there is more chance for error in focus in the "Which Camera took the shot" section when I'm panning and racking focus.
Judging by the opening carefully placed static shots, focus and lens quality aren't the main issues in the video comparison. Lower resolution video, video compression, and the 7D's video image processing would appear to be larger factors in reduced resolution in its video images.
