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

Although the price now is $100 over its predecessor, this update sees some improvement in sharpness levels making it above average for a ‘mid-range’ lens.  Given the specification and optical performance, the Sigma 17-50mm f/2.8 EX DC OS HSM  is an attractive alternative to rival offerings.
