The following from a Zeiss press release dated 08.30.12.
Carl Zeiss will display the new cine zoom lens Compact Zoom CZ.2 28-80/T2.9 at the IBC in Amsterdam, the leading international trade show for film, radio and television, from September 7 to 11, 2012 in hall 11 booth G64. The new Compact Zoom CZ.2 28-80/T2.9 by Carl Zeiss is a cine zoom lens ideally suited to a wide variety of shooting situations. It is easy to handle, compact and versatile. It takes pictures in 4K resolution — in full format. This is the second Compact Zoom CZ.2 lens from Carl Zeiss, complementing the Compact Zoom CZ.2 70-200/T2.9 presented in April at the NAB Show 2012 in Las Vegas for the longer focal length range. For color rendition, contrast and other parameters such as great flare suppression, calibrated focus scales, consistent aperture over the zoom range, round iris the new CZ.2 family is closely aligned to one another, making these lenses ideal for attaining a con- sistent optical performance when changing lenses.
Everyone is talking about the Rokinon line of lenses. Also known as Bower or Samyang depending on what country you reside in. They’re all the same lenses just different badges. Rokinon lenses are an excellent alternative to pricey cinema lenses mostly due to their cheaper, featureless construction. These lenses don’t come with any zippy auto focus motors nor do they offer camera controlled aperture functions. They still (as in non-motion) photography lenses with completely manual controls. Maybe a pain for those used to automatic lenses from Nikon or Canon, but great for those looking for an entry level cinema option. The lenses are commonly available in Nikon F or Canon EF mount.
