Summary: The Sigma 18-250mm F3.6-6.3 DC Macro OS HSM is one of the best of the current bunch of SLR superzooms, with decent optics, fast autofocus and effective image stabilization. It's a reliable performer, and its close-up capability is handy too.
Pros: 13.9x focal length range with impressive closeup capability, ideal general purpose / travel lens, Fast, quiet autofocus, Effective image stabilization (about 3 stops benefit at all focal lengths), Good build quality, smooth zoom ring action and limited zoom creep
Cons: Somewhat soft wide open in the middle of the zoom range, Very strong pincushion distortion across much of the zoom range
Conclusion: The Sigma 18-250mm F3.5-6.3 DC OS HSM, perhaps unsurprisingly, seems very much to be a case of 'take the 18-200mm OS , make it longer', and exhibits much the same characteristics as the older design.
Pros: Huge 13.9x focal length range, ideal general purpose and travel lens, Good image quality in the wide to short telephoto range, Fast, quiet autofocus, Low distortion (for a superzoom), Good build quality, smooth zooming action and no zoom creep
Cons: Very inconsistent sharpness through the zoom range - extremely soft at 135mm, Soft corners at almost all focal lengths, Image stabilization not as effective as on similar lenses, especially at telephoto end
Summary: Superzoom lenses are often full of compromises, but in this 18-250mm lens from Sigma, the compromises are few and far between. It may be the case that shorter zoom ranges may yield better performance overall, but if you're after a convenient all-in-one lens for travel, then the sharpness delivered...
Pros: Very good performance for a superzoom, Effective optical Stabilisation, Compact size, Light weight, Good build quality
Cons: f/6.3 max aperture at 250mm is relatively slow, No full time manual focus override (which isn't really much of an issue)

Summary: Sigma 18-250mm F3.5-6.3 DC OS HSM er et rigtig godt bud på et all-round objektiv, da der er tale om et objektiv med en brændvidde der gør det muligt at fotografere både landskab, portrætter, makro og meget andet, med ét enkelt objektiv.
