    Overview

    The Carl Zeiss Vario-Sonnar T* 100-300 mm f/4.5-5.6 C/Y is a manual-focus telephoto zoom known for excellent sharpness, color, and contrast, often rivaling primes. Optically, it performs best at f/8 across the frame, with good center sharpness wide open. Weaknesses include front element rotation complicating polarizer use, lack of a tripod collar, and potential haze in rear elements. Build is sturdy metal and rubber, but handling is tricky due to push-pull zoom and manual stabilization. It suits landscape and tripod-based photographers who prioritize optical quality over convenience.
