Description
Apo Sonnar T* 2/135
Turning far to near
Enjoying the evocative atmosphere of dusk against a dreamlike backdrop – as an inconspicuous observer, the tele lens lets you experience this unique moment from the distance. Detached from the background, the Apo Sonnar T* 2/135 enables an incomparable interplay of soft evening light and radiant colors. Offering the utmost flexibility in a wide diversity of situations, this tele lens can also capture the actor’s emotions on the stage from the third row and take breathtaking portrait photos.
Apo Sonnar T* 2/135
Design
A lens design with relatively few glass-to-air surfaces, invented by Dr. Ludwig Bertele at ZEISS in 1930 to provide the fastest lenses of that day for 35 mm photography offering speeds up to f/1.5 and well controlled veiling glare. This is where the name comes from, containig the German word for sun, ’Sonne’, the symbol of utmost brightness.

Features
Apochromat
Because this lens is an apochromat, chromatic aberrations (axial chromatic aberations) are corrected with elements of special glass with anomalous partial dispersion. The chromatic aberrations are therefore significantly below the defined limits. Bright-dark transitions in the image, and especially highlights, are reproduced almost completely free of color artifacts.
High-Speed Lens
Impressive photographs captured in low light always begin with a fast lens for a system or SLR camera. Because, a fast, high-performance lens captures as much light as possible. And a lens with a large maximum aperture leads to the best results when shooting in unfavourable light.
Close focusing distance
The 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.
Excellent resolution and high contrast
Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.
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.
