Sirui 56AS12E-W

85 out of 100 low confidence 5 reviews

This lens is praised for its affordability and quality, especially for portrait and interview photography. Users love the bokeh, color rendering, and dreamy look at f/2.2, though autofocus is slower than some other lenses and video mode has a minor reset issue. It is an APS-C lens, so full-frame users need to use Super 35 mode.

Pros
  • Affordable price
  • Great bokeh
  • Good autofocus
  • Beautiful color rendering
  • Dreamy look at f/2.2
Cons
  • Slower autofocus than 75mm
  • Video mode reset issue
  • APS-C only, not full frame
