What Buyers Say
Sirui 56AS12E-W
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.

- 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
