Distagon T* 2/25

Take a different view

The Distagon T* 2/25 enables creative photography with interesting perspectives – even in difficult lighting conditions. Without a tripod, exquisitely sharp, wide-angle shots work every time. The large angular field creates a dynamic yet natural effect. With excellent image quality from the widest aperture onwards, the Distagon T* 2/25 achieves great results – from interiors to stunning outdoor expanses.

Useful features such as two aspheric lens elements surfaces to correct distortion and a floating elements design ensure that you can vividly capture details framed from your own, unique perspective.

Design

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.

Distagon with 11 lens elements in 10 groups
Lens with aspheric optical surface
Lens made of special glass with anomalous partial dispersion
"Floating Elements" design

Features

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.

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.

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 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 ZEISS SLR lenses are crucial to favorable rendition of highlights in the fore and background.

High-Speed Lens

Great low-light shots start with a great lens for your SLR camera. A high-speed lens captures as much light as possible. A lens with a wide maximum aperture offers the best results in difficult lighting conditions.
