- sharp, almost comparable to prime lens
- very useful zoom range, easy to capture portrait to tele shots (crop 1.5x)
- SDM is more reliable than the one in 16-50, maybe because there's no external moving parts
- weather resistant is useful, i wash it under shower after going to beach
- useful F2.8, respectful sharpness and contrast at wide open
- Moden SMC coating gives very good anti-flare ability and high contrast
