|Introduction | Panasonic Leica DG Summilux 15mm F1.7 ASPH mounted on Olympus OM-D E-M1: High Peak Sharpness | Panasonic Leica DG Summilux 15mm F1.7 ASPH versus competition | Conclusion|
Panasonic has introduced a high-speed Leica 15mm (30mm equivalent) f1.7 for everyday use. Read on to find out how well it performs.
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 purists may protest at the use of the term ‘Summilux’ to describe the model’s maximum aperture – it’s usually reserved for f1.4 lenses only, but at f1.7 this new 15mm Micro Four Thirds lens is fast while remaining compact and relatively light in weight.
With a 46mm filter thread and a minimum focus distance of just 7.87” (0.2m), this model weighs in at just 4 oz (115g) and measures 36mm in length. The lens is available for pre-order at $599.
