Overview

Description by Zeiss:

With a field angle of 110°, the super wide-angle Distagon T* 2,8/15 is the ideal companion when it comes to capturing events in a way that makes them dynamic and extraordinary. Whether salt crystals or drops of water – its integrated lens shade and standard filter thread afford the front lens optimal protection from wind and weather.

The technically impressive features of the Distagon T* 2,8/15 include extraordinary chromatic aberration correction as well as two aspheric lens elements, special types of glass with exceptional partial dispersion and a floating elements design guaranteeing high image quality from close-up to infinity. Allowing you unlimited possibilities to let your imagination run free.

Aspherical design
zeiss_aspherical_design

The aspherical lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.

Floating Elements Design

zeiss_floating_elements_design

State-of-the-art camera techniques and high-resolution digital image sensors increasingly demand more from the lenses. The modern floating element design compensates aberrations of the Carl Zeiss SLR lenses at different distance settings. This is accomplished by changing the axial distance of single lens elements or element groups to each other. The adjustment of the element distance is coupled to the distance setting so that it always results in the right correction. The mechanical design of these lens elements is very complex and the workmanship must be particularly exact – both specialties of Carl Zeiss.

Excellent resolution and high contrast


Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.

Virtually distortion-free optics
Dramatic perspectives and a view from extraordinary image angles – SLR lenses from Carl Zeiss open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape.  This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.

 

Homogeneous image quality throughout the image fieldZEISS lenses are famous for their extraordinary image quality. Even with challenging subjects, perspective, color and light are optimally rendered – throughout the entire 35 mm image field. For this reason, we place great emphasis on particularly high image quality, e.g. low distortion and outstanding stray light reduction for rich colors.

Reviews

This is a two-in-two test, the DXO Mark labs check out the Zeiss lens performance difference between Canon and Nikon mounts (5D Mark II vs D3x) and then pits the Zeiss versus the Sigma: 

"In DxO Mark’s testing the quality of the Zeiss lenses over the Sigma lens is very clear. A DxO Mark score of 17 for the Sigma lens is an OK score for a lens with this extreme wide angle: there are few wider corrected lenses on the market to cover full frame 35mm so if the lens were considered in isolation the score might possibly be accepted as a reasonable consequence of the focal length. However, when you look at the other lenses in this category the score does not look quite as good. Zeiss on the other hand have a shining DxO Mark score of 23 for their Nikon version, the highest for any lens of 20mm or wider with a Nikon FX mount (the Canon version scores a creditable 21). The Zeiss lens is much more expensive, nearly 4 times the price of the Sigma, so there will

"The lens has an exceptional haptics and build quality. If you compare the RAW images without any software lens correction to those with a lens correction profile applied correction in post processing (Adobe Lightroom 4.1 and Camera Raw 7.1 already have profiles for that lens), you can see that this lens needs only very little distortion correction. It providies exceptional center sharpness already at F2.8 and vignettes at open aperture in a significant degree but correction is just one click away in many raw processors and not always favored.

"o you see that at F5.6 all three candidates deliver very sharp centers, the Nikon zoom shows slightly better contrasts here. As the images from the Zeiss and the Samyang were about 0.5 to 0.8 F-stops overexposed and had to be dimmed in that degree for better comparison, the difference in contrast may also be caused a little bit by that. I recognized quite often that the images with the Nikon zoom were about 0,2 to 0,8 stops shorter exposed which may be caused by the different degree of vignetting.
