The T designation indicates Zeiss's single-layer anti-reflection coating — an early but effective coating system that delivers improved contrast and colour accuracy over uncoated glass. The Tessar formula — universally known as the \"Eagle Eye\" — delivers exceptional sharpness, natural colour rendering, and outstanding contrast in a compact and solidly built package. In M42 mount, it adapts effortlessly to virtually any modern mirrorless or film body via adapter.
