Carl Zeiss ZE 2/25mm (Canon)

High-speed perspectives

The high-speed Distagon T 2/25 enables creative photography with interesting perspectives. Whether you are shooting landscapes, architecture or photo documentaries, you will always be able to capture detail-rich scenes - even in difficult lighting conditions. Without a tripod, wide-angle shots with sharp contrast edges also work every time. The large angular field creates a dynamic yet natural effect. With excellent image quality already starting from the widest aperture, the Distagon T 2/25 achieves great results in interior rooms.

Carl Zeiss has virtually eliminated the chromatic aberrations on this lens thanks to a special optical construction and selection of optical glasses. Two aspheric lens surfaces correct distortion and image field curvature. The floating elements design creates high imaging performance, regardless of the distance of the subject.

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
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.

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.

Ideal aperture with nine blades
Photographers want to guide the observer through the image. Minimal depth of focus is often used as a design element. This keeps the background intentionally blurred to keep the attention of the observer on the main subject. These different representations of the blurred areas, as well as the quality of the transition, are referred to as the Bokeh of a lens. The finely tuned features of the optical design on Carl Zeiss SLR lenses ensure a particularly harmonious effect of the blurred areas of the image. The nine diaphragm blades and the resulting, virtually circular aperture on Carl Zeiss SLR lenses are crucial to favorable rendition of highlights in the fore and background.
