Pros
- Surprisingly great performance for a kit lens.
- Fast focusing even with older cameras.
- Pretty compact size and doesn’t get much larger when fully zoomed in or out
Cons
- Honestly, not much considering I had low expectations to begin with due to this being a kit lens. While I understand that kit lenses have improved over the years, I just never know what to expect these days.
