The renowned German lens maker Carl Zeiss has accused the South Korean lens maker Samyang of copying its designs. As a result, the Samyang lenses at the center of the dispute are being pulled by distributors and retailers.

The Swedish website Monitor reports that the Samyang Premium XP 50mm f/1.2 and 85mm f/1.2 lenses are the ones Zeiss has issues with.

Hands-On With the ZEISS LWZ.3 21-100mm T2.9 – T3.9

Here at IBC 2016, we go hands-on with the freshly announced Zeiss LWZ.3, the newest addition to their lightweight zoom range. Although the lens gets slower at the far end, from T2.9 down to T3.9, it might nevertheless be the next big thing for documentary work. Make sure to read Nino’s in-depth article for all about the details of this lightweight cine zoom lens. 

Hands-on with the Zeiss LWZ.3

As there is no such thing as the perfect lens (14 – 200mm T 1.5 with full frame coverage in a 1,2 kg parfocal lens for $800, anyone?) you’ll always get some downsides, that’s for sure. In the case of this lens, even though it is really lightweight for the focal range it covers, there are also some downsides to it. The Zeiss LWZ.3 only covers super35 sized sensors, for example. The bigger Zeiss Compact Zoom versions cover full frame, but they are double the price for half the focal range.

The one thing I find really annoying is the drop of T-stop towards the end of the focal range of this lens. But Zeiss has managed to implement a technology called gradiant T-Stop which will ensure very smooth and linear transition of aperture over the focal range.

Zeiss Adds 15mm, 18mm, and 135mm DSLR Lenses to the Milvus Line

 Gear  Comments Off on Zeiss Adds 15mm, 18mm, and 135mm DSLR Lenses to the Milvus Line

Expanding upon the high-end manual focus line of Milvus lenses for DSLR cameras, today Zeiss announced they are adding three new additions. These new lenses — a 15mm f/2.8, 18mm f/2.8, and 135mm f/2 — will feature the same solid optical quality housed within a beautiful barrel design that the Milvus line is known for. Created for both high-resolution photography and videography, the new lenses will begin shipping at the end of October.

All Zeiss Milvus lenses have a floating elements design and use T* anti-reflective coating. Together, many common image errors are compensated for right in camera, such as flare and ghosting.  The lenses are dust and weather resistant, and feature a full-metal barrel.

The Zeiss Milvus 2.8/15 uses a Distagon lens design with 15 elements in 12 groups, including two aspheric lenses. The super wide-angle lens offers a 110-degree field of view. Something fairly rare for super wide-angle lenses like this is that the 2.8/15 also has a 95mm filter thread.

The Zeiss Milvus 2.8/18 is a compact super wide-angle lens that also uses the Distagon lens design. There are 14 elements in 12 groups packed in, with two aspheric elements. The 2.8/18 has a 99.9-degree field of view and can focus as close as 0.25 meters, making it useful in architecture and landscape applications. The filter thread size of this lens is a more standard 77mm.

Camera and cine lenses need to operate perfectly in extreme conditions, withstanding everything from scorching heat and bitter cold to sandstorms and severe vibrations. The video shows how Carl Zeiss researchers systematically submit lenses to extreme stresses in order to arrive at findings that can help in future lens design and development. The video was shot with a Sony NEX-FS100 and Carl Zeiss ZF.2 SLR lenses with an F to E mount adapter.
