Out of Sigma's freshly reorganised lens line-up comes a new ‘Art'-branded 50mm f/1.4 with claims of superb design and image quality. Richard Sibley puts it through our rigorous testing procedure to discover what truth these rumours hold

If you shoot a lot at wide apertures (1.4 to 2.8) no 50 can beat it. I\'m still amazed when I chimp my images. As an old Leica-M shooter, I have a style that relies on lenses in the 28mm to 75mm range. My basic lens is the 18-35 Art, and this 50 is my \"long\" lens.

Unbelievably sharp, even wide open; Great colour; Good (not great) bokeh; Very well made, like all Art series lenses; Balances well on a D7100 with grip
