Back in May we featured an Olympus commercial that was shot entirely with the camera it was promoting (the Olympus PEN E-PL1), lending credence to the camera’s video capabilities.

Panasonic recently posted a behind-the-scenes video to its YouTube account showing how a new ad for their Lumix G2 camera was made. However, a close look at the video seems to reveal that most of the filming was actually done with Canon 5D Mark II cameras and a set of L lenses. Most of the comments on the video poke fun at this, with one commenter saying,

You shoot a commercial of an HD camera with another HD camera but post the footage in standard definition? Fail.

The takeaway for camera companies: eat your own dog food.
