Zeiss Distagon T* 15mm f/2.8 ZE for Canon

With a field angle of 110°, the super wide-angle Distagon T* 15mm f/2.8 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* 15mm f/2.8 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
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
Today’s camera technologies and high-resolution sensors demand continuous improvement of lens performance. Thanks to the use of the latest floating element design principles, optical aberration effects in ZEISS lenses are reduced to a minimum throughout their entire focusing range. This is achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision – both of which are key competencies of ZEISS.

Excellent resolution and high contrast
Richly saturated and vivid colours are a must in the creation of lasting impressions. However, stray light within an optical system leads to a lightening of the image that is particularly noticeable in the shadows. This reduces image contrast, with the result that exposures lack contrast and appear faded. To avoid this, ZEISS combines various specially developed technologies to reduce the undesirable effects of stray light.

Virtually distortion-free optics
Dramatic perspectives and a view from extraordinary image angles – SLR lenses from 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 field
ZEISS lenses are famous for their extraordinary image quality. Even with challenging subjects, perspective, color and light are optimally rendered – throughout the entire 35mm 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.
