I was ok with all aspects of the rather pricey Panasonic 12-35mm f2,8 lens as it was specifically marketed as an "optimized for HD Video" lens by Panasonic and we needed the constant aperture, smooth zooming and image stabilization.
Except that the lens is not "constant aperture". The aperture blade design has "jumps" at around 14mm, 17mm, 20mm and 25mm that result in exposure variations. See what I mean here: http://www.youtube.com/watch?v=u2vjROGkgUA
Not a problem for still shooters but this is not at all good for video.
