Lens Review
Introduction | Sigma 18-35mm DC HSM A Canon lens performance | Sigma 18-35mm f/1.8 – best performing APS-C zoom in our database | Sigma 18-35mm F1.8 DC HSM A Canon versus primes | Conclusion

Although it is unlikely a user would buy several full-frame wide-angle lenses specifically for an APS-C format camera, the fact remains that the Sigma 18-35mm f/1.8 DC HSM is an outstanding performer optically.

If we want to be picky, the Sigma lacks image stabilization and the zoom range isn’t as wide as some rivals, but at $799 the lens is remarkable. Like the Nikon AF-S Nikkor 14-24mm f/2.8G ED before it, the Sigma is likely to be viewed as a disruptive innovation and genuinely means we no longer have to choose between the flexibility of a zoom over the imaging characteristics that were once only available with a prime.
