Sony Carl Zeiss Sonnar T* FE 55mm F1.8 ZA

[1] Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 82.5mm.

The lens itself is made of a thin weather resistant aluminum shell over plastic internals.

The lens showcases a minimalist black exterior with a Zeiss badge on the side of the barrel, nearly identical to Sony's Zeiss-approved 24mm F1.8 APS-C lens.

[2][3] The lens is exceptionally sharp from its maximum aperture of f/1.8 across the frame.

[5] In high contrast environments the lens showcases some strong spherochromatism or "color bokeh".
