Sony FE 28mm F2

[1][2] 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 42mm.

However, neither converter can accept lens filters or are themselves weather resistant.

The lens is sharp straight from its maximum aperture of f/2.0, with only a mildly apparent fall-off in acuity toward the edge of the frame.

The lens also excels at low-light photography given its fast maximum aperture of f/2.0 and exceptional coma control.

When shooting RAW the strong barrel distortion has to be corrected by software.
