The Carl Zeiss Distagon T* 2,8/15 ZE 15mm f/2.8 Lens For Canon  With a field angle of 110°, is the ideal companion when it comes to capturing events in a way that makes them dynamic and extraordinary. Allowing you unlimited possibilities to let your imagination run free.
Widen your imagination
Infinitely wide horizons, cramped interiors or small objects in large surroundings - with the Distagon T* 2,8/15, you can deliberately orchestrate extreme perspectives with remarkable precision.
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.
When wide angle views go to extremes and beg the control via an SLR viewfinder, which means that the back focal distance has to be much larger than the focal length, a retrofous design called Distagon is the right choice.
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
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
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 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 field
ZEISS 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.
