As part of our ongoing collaboration with DxOMark we've added more lenses to our test data comparison widget. These include a range of 70-200mm zooms from Canon, Nikon, Tamron and Sigma, and the Nikon-mount version of the Sigma 35mm F1.4 DG HSM tested on both the D7000 and D800. Click through for links to view these lenses in our widget, and for the full data on DxOMark.

We've also made a couple of changes to our lens review pages. Sharp-eyed readers may already have noticed that we've changed the scale on our MTF graphs, which now go up to 3000 lph; this allows us to present data measured on the 36MP Nikon D800 correctly. We've also added a version of our interactive scoring widget to the Conclusion page, which allows you to easily compare the strengths and weaknesses of the lenses we've covered.
