Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM review: Digital Photography Review

Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM review: Digital Photography Review | Photography Gear News | Scoop.it
Our review of the Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM. The latest version of Sigma's stabilized superzoom is smaller and lighter than the existing non-macro version, yet is able to add improved close-focus performance, helping it compete with the similarly-sized Tamron 18-270mm F/3.5-6.3 VC PZD. These long-range all-rounders are a popular choice, so we've had a look at how Sigma's latest performs. We've also added DxOMark's test data for a selection of its competitors, to give a sense of context.
