Carl Zeiss 35mm f/1.4 Distagon breathing
The short video below shows near-to-far focusing for the Zeiss 35mm f/1.4 Distagon prototype, with the thought that it might be of some interest to video users concerned with “breathing”.
Note that the color is wrong (though not unpleasant), and quality is well below the original (courtesy of YouTube). You’ll want to set to 1080p and full screen to view comfortably, use the controls at lower right of the video.
