Best for
A heritage premium Zeiss binocular - the 7x42 Dialyt was a stalwart of serious birding, wildlife observation and general outdoor use for decades. 7x magnification is easier to hold steady than 8x, and the 6mm exit pupil is excellent for low light. Succeeded by the Zeiss Victory series but still widely used and loved.
Frequently asked questions
What do 'T*' and 'P*' mean?
T* is Zeiss's premium multi-layer anti-reflection coating applied to lens surfaces. P* is their phase-correction coating on roof prism surfaces, correcting the phase-split that otherwise softens roof-prism images. Both are essential to serious roof-prism binocular quality.
