The Zeiss Distagon T* 2/25 ZE 25mm f/2 Lens For Canon  enables creative photography with interesting perspectives - even in difficult lighting conditions. Without a tripod, exquisitely sharp, wide-angle shots work every time.
The wide angle Distagon T* 25mm f/2.0 ZE Lens for Canon EF Mount is the most advanced version of the legendary Distagon, a high-performance manual focusing lens with close focus capabilities, first introduced in 1961. The Distagon T* 25mm f/2.0 ZE is a recalculation of this design, with an exceptionally fast f/2.0 maximum aperture, for use with modern SLRs and DSLRs using either full-frame or smaller sensors.
This manually focusable ZE lens features electronic shutter control and additional electronic contacts to the camera. All existing exposure programs (P, AV, TV, M) and the AF confirmation function of the camera are supported; lens information (focal length and speed) is passed on to the camera. Certain functions that require the use of AF lenses (various scene modes, A-DEP) are partially unavailable.
Increasing the versatility of this 25mm f/2.0 lens is its close focusing distance of only 9.8", providing a wider perspective than usual. Combined with a digital SLR with a 1.5x crop factor, the lens has an effective focal length of 38mm and becomes a moderate wide angle lens.
This precision lens delivers breathtaking images. It is ideally suited for nature and landscapes, but you can get amazing perspectives on almost any subject from portraits to products...all you need is your creativity.
Exceptionally fast f2.0 maximum aperture provides superb low-light capabilities
Chromatic aberrations on this lens have been virtually eliminated, thanks to a special optical construction and selection of optical glass.
Two aspheric lens surfaces correct distortion and image field curvature, and the floating elements design creates high imaging performance, regardless of the distance of the subject.
The almost circular design of the aperture produces an exceptional "bokeh", beautifully reproducing the out-of-focus areas of the image.
This lens features a precise focusing mechanism with a large rotation angle. Operating it manually means controlling the picture with your fingertips.
Zeiss lenses are famous for the exceptional quality of the pictures they provide. They boast optimum control of glare and stray light to ensure brilliant images. No matter how demanding the subject, perspectives, colors, and lighting situations are reproduced perfectly - over the entire full-frame image field.
Take a different view
A beautiful landscape, a stunning piece of architecture or a fascinating photo documentary - capture scenes rich in intimate detail. Give each composition your own, unique perspective.
With excellent image quality from the widest aperture onwards, the Distagon T* 2/25 achieves great results – from interiors to stunning outdoor expanses. The large angular field creates a dynamic yet natural effect.
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.
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.
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.
Great low-light shots start with a great lens for your DSLR 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.
