The Sony AF 50 mm  f/ 2.8 Macro

The characteristics of  the Sony AF 50 mm  f/ 2.8 Macro (SAL50M28)

  • Compact macro lens with the closest focusing distance of 20 cm
  • The lens uses a double-floating element design to correct aberrations at all focal lengths.
  • A rounded aperture provides a beautiful out of focus background.
  • Focusing ring lock in AF mode.
  • Remember that the lens specifications may vary depending on the country.
  • Angles of view: 32° / 47° for APS-C
  • Depth of field scale: yes
  • Focus hold button: yes
  • Front lens: non-rotating

Thanks to the optical scheme the Sony AF 50 mm  f/ 2.8 Macro produces a high-quality image,  even sharpness and brightness across the frame, and no distortion. 

The Sony SAL-50M28 AF system operates very silently thanks to the system of floating elements, which in turn reduces spherical aberrations and astigmatism to a zero level, and provides accurate focusing at any focusing distance.

Pros:

  • very good image quality at f/2.8,
  • insignificant distortion,
  • well corrected coma and astigmatism,
  • exemplary operation in bright light
  • good autofocusing
  • good build quality

Cons:

  • too high level of vignetting at f/2.8,
  • visible chromatic aberration when wide open.
