Pros & Cons
👍 Pros
- Wide f/1.8 aperture produces smooth, creamy background blur ideal for portrait and low-light shooting
- STM autofocus motor operates quietly, which is beneficial for video recording
- Compatible with both full-frame and APS-C Sony E-mount cameras, covering a wide range of bodies
- Substantially more affordable than Sony's own 50mm f/1.8 lens

👎 Cons
- Firmware updates require an Android device — Mac and iOS users cannot perform updates directly
