Dialyt 8x56 GA T*

A classic that influences generations

When Carl Zeiss launched the first 10x42 Dialyt model on the market in 1968, the whole concept of binoculars was redefined. As a result, these classics from Carl Zeiss shaped a whole generation of binoculars. From form to function - the standard had been set.
The low light 56 x night-time binoculars continue to be a reliable and a long-lasting companion, and remain a fixed part of the product range of Carl Zeiss. They have proved themselves in everyday observation situations and are greatly appreciated for their timeless performance. Particularly in twilight and at night, the non-slip, robust binoculars provide good visibility and outstanding observational experiences.

    The classic binocular for field observation

    Especially in difficult light conditions

    Large, low light, 56 mm lenses and an 8 x magnification produce a steady image and a good overview. Despite the large lens diameter, at just 1.010 grammes it is hardly a heavyweight. The classic companion for night-time excursions with constantly improved optical performance.


    Outstanding image brightness

    Along with the large lens aperture, the low light and phase-corrected Abbe-König prism and the elaborate, constantly improved Carl Zeiss T* multi-layer coating give these binoculars the edge when it comes to observing birds and mammals that are active in the twilight hours, or for daytime observation in poor light conditions.

    Non-slip and robust

    The robust, tried and tested design has been popular for decades and remains the classic among binoculars. Technically focused on the basics, these binoculars are robust and extremely non-slip. Even the ergonomic design is timeless; the binoculars sit comfortably in the hand right from the very start.


    Classic design

    There are some products whose timeless design has influenced the appearance of subsequent generations of products. The Dialyt, with its timeless design, definitely falls into that category. Even today this classic is a favourite of nature and birdwatchers, who value its image quality and robust construction coupled with the classic design that goes back so many years. Proof of the timelessness of this product.

    Questions & Answers

    • What do the abbreviations mean?

      Meaning of the abbreviations


      Binoculars or spotting scopes with glasses that contain fluoride (FL) for sharper, higher contrast images with significantly reduced chromatic aberrations; Fluoride Lenses; a special, high-quality sub-category of the ED lenses


      Previously used to designate Dialyt binoculars with rubber armour


      ZEISS T* Multi-layer coating for extremely high transmission and low reflex susceptibility


      ZEISS Multi-layer coating (multi coating)


      P / P*
      Phase correction coating on the roof prisms, which provide a higher resolution of the finest detail structures. All ZEISS binoculars with roof prisms use this coating


      Previously used to designate binoculars that can be worn by people who wear glasses.
      Now all ZEISS binoculars and spotting scope eyepieces are suitable for people who wear glasses, so the "B" designation is no longer used


      Binoculars with mechanical image stabilisation


      Extra low Dispersion = low chromatic aberrations


      High Definition. HD is not a type of lens. Instead it describes the result of the ED lenses: very good resolution


      High Transmission = lenses by Schott with very good transmission properties.



      Smart Focus = Conventional binoculars require the focusing wheel to be turned 2.5 times in order to switch from the close focus to the maximum observation distance. The VICTORY SF only requires the wheel to be turned 1.8 times.
