Sigma 18-35mm f/1.8 DC HSM In-Depth Review

sigma 18-35mm f/1.8

dpreview just reviewed the new released world’s fastest f/1.8 zoom lens: Sigma 18-35mm f/1.8 DC HSM lens. This is a great lens from Sigma, as DxOMark score is even better than some prime lenses. And wins dpreview gold award at 86% overall score.

Conclusion from dpreview:

Pros
  • Super fast constant F1.8 maximum aperture
  • Excellent optics, even wide open
  • Fast, silent autofocus
  • Solid build quality without being over-heavy
  • Compatible with Sigma’s USB dock and Optimization Pro software
Cons
  • Restricted zoom range
  • Needs detailed AF microadjustment for best results
  • Inconsistent autofocus in difficult conditions even after microadjustment
  • Physically rather large for a standard zoom
Final word:

Sigma has been on something of a roll recently, with lenses like the 35mm F1.4 offering excellent optics at a very competitive price, and it’s clear from both technical tests and real world shooting that the 18-35mm F1.8 is following on in much the same vein. Its relatively narrow zoom range is undeniably a little restrictive, but on the other hand, the image quality it can offer over that range is absolutely stellar. It’s let down a little by inconsistent autofocus, which makes it difficult to get consistently sharp results every time when shooting wide open. But if you’re prepared to live with this, the 18-35mm is capable of delivering truly exceptional results.
