The Sigma 50mm F1.4 DG HSM 'Art' is a fast normal prime for full frame cameras, with an unusually complex optical design. Its premium price tag of $950 / £850 makes it substantially more expensive than either its predecessor, or Canon and Nikon's 50mm F1.4 lenses. However Sigma's recent high-end offerings such as the 35mm F1.4 DG HSM and 18-35mm F1.8 DC HSM have been truly excellent, so how does the new 50mm measure up?

In this 'Lab Test report' we're publishing full lens test data (as usual prepared by our collaborators at DxOMark) in our unique lens data widget, and presenting our own analysis of what it all means. This allows us to present the test data in the timeliest possible fashion - we plan to follow this with a full review in due course.
