Sigma EX DC OS HSM 583101 17-50mm

Once a top pick in the superzoom category, this lens now faces fresher, sharper competition that makes it harder to recommend. The drop from 80 to 61 reflects how far the market has moved. Still decent for casual travel photography, but no longer the go-to choice it used to be.

The superzoom category has gotten crowded, and this lens now faces stiff competition from several newer options. The Sigma Contemporary 16-300mm f/3.5-6.7 DC OS offers a wider starting focal length and similar reach, often with better sharpness across the frame. The Tamron Di III 18-300mm f/3.5-6.3 Di III-A VC VXD brings faster, quieter autofocus and slightly brighter aperture at the long end. For mirrorless shooters, the Nikon NIKKOR Z 28-400mm f/4-8 VR stretches even further while maintaining respectable image quality. The Panasonic LUMIX G Leica DG Vario-Elmarit H-ES50200 is a different beast entirely, a shorter but optically superior telephoto that outclasses this lens in sharpness and contrast. Even the aging Canon EF-S 18-135mm f/3.5-5.6 IS USM holds its own with smoother zoom action and better build quality. Where this lens once sat comfortably in the top tier, it now feels like a middle-of-the-pack option that struggles to justify its price against fresher designs.

This lens has slipped from a strong recommendation to a more cautious one. The core formula hasn't changed, but the market has moved on. Newer competitors deliver better sharpness, faster autofocus, or more versatile focal ranges at similar or lower prices. The image stabilization and weather sealing are still welcome, but they're no longer standout features when rivals offer the same. If you already own this lens, it remains a capable travel companion. If you're buying new, you owe it to yourself to test the Sigma 16-300mm or Tamron 18-300mm first. The value proposition has eroded significantly, and a score drop from 80 to 61 reflects that reality.
