    Overview

    The Carl Zeiss Vario-Sonnar T* 17-35mm f/2.8 is a legendary but heavy (almost 1 kg, 95mm filter) ultra-wide zoom, praised for its optical quality at 17-24mm. However, MTF charts show significant astigmatism and sharp corner resolution drop-off, as if designed for APS-C. Build is robust, but it requires a complex conversion for Canon EF mount. Best suited for enthusiasts willing to tolerate manual focus and weight for Zeiss 'mojo' at wide angles.
