Sigma 24-70mm f/2.8 DG DN ART II Review: Worth the Upgrade?

The 24-70mm f/2.8 is the lens that lives on your camera between jobs, travels to every event, and gets pulled out when clients don't give you time to think. So when Sigma updates the ART version for Sony E and L-mount shooters, it matters. The fact it's already outselling everything else at B&H isn't hype, it's photographers voting with their wallets against paying Sony or Lumix prices for the same focal range. The question the review actually answers: does the second generation fix the compromises that made the first one a 'good enough' rather than 'obviously right' choice. If you're on Sony or L-mount and your 24-70 is getting long in the tooth, read this before you default to the native option.
