Sigma 18-200mm f/3.5-6.3 DC Review

This is one of the cheapest lens in this category, and it's available in Canon, Nikon, Pentax, Sigma and Sony mounts. It doesn't offer image stabilisation, and so is best suited to cameras with on-board IS.
Pros:
  • Price
  • great chromatic aberration control
Cons:
  • Inconsistent performance
  • low resolution at 200mm

One of the limitations with a kit lens is that you don't have a great focal length range, especially at the telephoto end of the scale. This Sigma 18-200mm f/3.5-6.3 is not only small and light but also has an impressive optical stabiliser built-in (Canon and Nikon fits).

For starters, anybody who expects stellar optical performance from a 11,1 zoom, better stop reading right now. It is not going to happen, not with this one, nor with the Nikkor. I got this lens in a hurry, because I needed an all-purpose lens to cover a spur-of-the-moment client event.
Pros:
  • ? Solid build quality & finish
  • surprisingly good focus speed and accuracy
  • ? Overall pretty decent optical performance
  • except at the very long end (in my sample)
  • ? Pretty unobtrusive internal focus
  • no rotating front-end.
Cons:
  • ? Chromatic aberration and purple fringing on highlight edges throughout the focal range, especially wide open
  • This can, however, be easily corrected in post or even in-camera (select Nikon models), ? Pronounced barrel distortions at the wide end, some pin cushion in the medium to long focal...

  • Highly effective optical stabiliser
  • Price
Cons:
  • Falloff in sharpness at 200mm
  • CA towards edges can be noticeable along high contrast edges

Wonderful sharp lens for the price

I spent a lot of time comparing this lens with others as a potential replacement for the Nikon 18-55 kit lens and the Tamron 18-200mm I had been using as a Hiking Lens. I gave the Tamron away and decided on the Sigma following detailed study of DPreview.com great lens sharpness and performance...
