Panasonic Leica DG Summilux 15mm F1.7 ASPH lens review: Prime performer

Introduction As the equivalent field of view of a 30mm, this well-made metal-barreled lens is ideally suited for available light, day-to-day applications such as street photography, reportage and landscapes. It has 9 nine elements arranged in 7 groups and adopts three aspherical-shaped lenses to reduce distortion and spherical aberration, while Nano coating is employed for reduced ghosting and flare. Like the previous Leica-branded 42.5mm (85mm equiv.) f1.2 this new lens features an aperture collar and an internal focus mechanism (so there’s no extending barrels) with a newly developed stepper-type AF motor suited to stills and video capture.Leica
