Lens Review
Introduction | Sigma 17-70mm f/2.8-4 image quality evaluation | Sigma 17-70mm f/2.8-4 versus competition | Conclusion

When evaluated against its pricier sibling, the similar DxOMark scores suggest a similar image quality however at $670 Sigma 17-50mm f/2.8 EX DC OS HSM Nikon measured a very respectable 10P-Mpix vs 8P-MPix for the 17-70mm. What’s more the 17-50mm f/2.8 also has more consistent performance over the focal range, it’s only when the other metrics are taken into account that the overall score of the 17-70mm starts to approach the 17-50mm f/2.8.
