Carl Zeiss Presents Two New Lenses
Industry customers benefit from exceptional image quality with the Distagon T* 2.8/15 and the Apo Sonnar T* 2/135
OBERKOCHEN, GERMANY – 6 November 2012Carl Zeiss has two new lenses in its line: the new Distagon T* 2,8/15 super-wide angle lens is already on the market, and the Apo Sonnar T* 2/135 will be delivered from December onwards. Both lenses are available with F mount (ZF.2), EF mount (ZE) and M42 mount (Z-M42-I) and are designed for use in creative photography as well as industrial applications.
The Distagon T* 2,8/15 features an extra large field angle of 110° and speed of 1:2.8. Through its extremely large field angle, the lens allows either foreground or background emphasis. Because the super wide angle also enables focusing on details close in, the exaggerated graduation of proportions results in additional impression of depth with outstanding definition throughout the picture – from close-in to infinity. With other super-wide angle lenses, aberrations such as distortion can easily occur. The Distagon T* 2,8/15 balances these out and delivers naturally proportioned pictures. "With the high-speed Distagon T* 2,8/15, Carl Zeiss sets the standard in super wide-angle photography," says Dr. Michael Pollmann, Consumer Lenses Program Manager in the Camera Lens Division of Carl Zeiss AG.
With its 135 millimeter focal length, the Apo Sonnar T* 2/135 is the longest tele lens in the SLR lens range. Anyone who wishes to capture detailed images from long distances is on the right track with the Apo Sonnar T* 2/135. At any aperture, it delivers impressive results – brilliant detail, high contrast and maximum definition. A special, variable arrangement of the lens elements ensures excellent image quality across the entire focusing range from 0.8 m to infinity. As it is an apochromatic lens, chromatic aberrations are corrected by lens elements made of special types of glass with exceptional partial dispersion. Therefore, the chromatic aberrations are far below the limits otherwise defined.
Applications in Photogrammetry
The robust all-metal body of both the Distagon T* 2,8/15 and the Apo Sonnar T* 2/135 is designed for extra-long service life. Thus, both are optimally suitable for industry customers. The German Aerospace Center (DLR), among others, uses an SLR lens from Carl Zeiss in an airborne system for the monitoring of traffic and potential hazards. This allows razor sharp images to be conveyed almost in real-time – in the case of a major event, for example – which benefits security forces and other groups. Due to its resistance and performance, the ZEISS lens also withstands adverse weather conditions. "Carl Zeiss enjoys a very good reputation in the area of photogrammetry. We were well-advised. If we set the lenses to infinity, they focus on infinity. This is exactly what we wanted," says Project Manager Dr. Frank Kurz from the Remote Sensing Technology Institute at the DLR.
Like with all other SLR lenses of the ZE and ZF.2 series, the Carl Zeiss T* anti-reflective coating and the advanced treatment of the lens edges with special dark black lacquers ensure resistance to reflections and stray light.
Sigma
Sigma announced the price and shipping date for their new 35mm f/1.4 DG HSM lens. More info on the lens, including MTF charts and lens design, can be found here.
Sigma 35mm f/1.4 DG HSM lens technical data:
- One “F” Low Dispersion (FLD) glass lens and four Special Low Dispersion (SLD) glass lenses to ensure exceptional correction of lateral and axial chromatic aberration, the latter of which cannot be corrected in post production
- A floating inner focus system to provide extremely high optical performance for close-up photos
- Super Multi-Layer Coating to reduce flare and ghosting and provide sharp and high contrast images even in backlit conditions
- A HSM (Hyper Sonic Motor) that ensures high speed, accurate and quiet AF
- Rubber incorporated into the attachment part of the lens hood, and an improved redesign of the lens cap and AF / MF changeover switch have been improved
- Thermally Stable Composite (TSC), which has high affinity to metal parts, that are housed internally, increases overall functionality, lifespan, and quality of the lens
- A rounded 9 blade diaphragm creates an attractive blur to the out-of-focus areas of the image
- A newly developed USB dock, which will be sold separately and exclusively for new product lines, can be paired with new Sigma Optimization Pro software to update the lens firmware and adjust parameters, such as micro focus adjustment
- Price: $899
