Today, Leica has announced a new addition to the venerable M lens roster, the Summilux-M 90mm f/1.5 ASPH. As the fastest 90mm lens Leica has ever produced, the new 90mm Summilux-M follows in the footsteps of the recently-introduced Nocitlux-M 75mm f/1.25 ASPH, pushing the limits of optical performance.

And indeed, there are many similarities between the two lenses. Under its precision-machined black aluminum skin, the 90mm Summilux employs a cutting-edge optical design, reminiscent of the latest 75mm Noctilux. For the 90mm, Leica has gone with eight elements arranged into six groups, all crafted from glass with high anomalous partial dispersion and low chromatic dispersion, two of which are aspherical, as well as a floating lens element group to guarantee consistent performance across the entire focus range.

Depth of field is equally razor-thin between the two lenses, both just half that of the 50mm f/0.95 Noctilux-M ASPH. If you’re worried that the 90mm doesn’t carry the Noctilux moniker or corresponding unbelievably-low max aperture number – don’t. The new 90mm Summilux focuses down to 1m, the same as the 50mm Noct. But with almost double the focal length, the 90mm easily overcomes the aperture disparity of f/0.95 vs. f/1.5 to best the legendary King of the Night, at least in producing shallower DOF.

And with an 11-blade rounded aperture, the resulting bokeh is buttery smooth and absent of any harsh artifacts. Basically, if you liked the 75mm Noctilux, the 90mm Summilux offers more of the same: Impressive sharpness at the point of focus, even wide-open, with three-dimensional subject separation and creamy bokeh goodness galore everywhere else. Stopped down (but really, why would you?), the 90 Lux delivers unbelievable resolving power from corner to corner.

Both the 75mm Noctilux and 90mm Summilux feature near-identical dimensions and weight, sharing the same 67mm filter size and 91mm overall length. The new 90mm tips the scales at 1010g, just 45g less than its 75mm cousin. Make no mistake, these are both considerable pieces of glass with a noticeable heft.

While designed for a digital rangefinder like the M10, this lens mates perfectly with the SL2 using the Leica M-Adapter-L. A more substantial grip on a heftier body will provide a nicely balanced shooting platform while live view on the high-res OLED EVF aids in focus accuracy. Add in the 5.5 stop in-body image stabilization and electronic shutter allowing for wide-open shooting even in bright light, and the SL2 could make an ideal pairing for the 90mm Lux. We had the same feeling with the 75mm Noctilux. So no surprise here.

Pricing and Availability

The Leica Summilux-M 90mm f/1.5 ASPH is expected to start shipping within the next few weeks at a price of $12,995.

Press Release

Leica Camera proudly announces its latest achievement in the world of fast-aperture lenses for its storied Leica M rangefinder system. The new Leica Summilux-M 90 mm f/1.5 ASPH. is the brand’s latest in the long line of famed Summilux lenses, now for the very first time in the 90 mm focal length. This new lens is perfect for portraits with an incredibly shallow depth of field, even half that of the legendary 50 mm Noctilux-M f/0.95 ASPH., allowing a striking separation of its razor-sharp subjects from the dreamy backgrounds with a lovely bokeh. Whether used on a Leica M10 or on the new Leica SL2 with the M-Adapter L, the Leica Summilux-M 90 mm f/1.5 ASPH. promises to bring portraits to life with new levels of sharpness and its own signature look.

The Summilux-M 90 mm f/1.5 ASPH. is distinguished by an elaborate construction comprised of 8 lens elements, two of which are aspherical in design and made of specialized glass types, arranged in 6 groups. A floating lens element ensures the superior optical performance of the lens is maintained across the full focus range. This advanced lens design and fast maximum aperture it achieves gives the lens its unique image rendering and unparalleled performance.
