Leica M-Mount

Review

The Leica Summilux-M 90mm F1.5 ASPH is a remarkable lens that epitomizes the craftsmanship and optical performance characteristic of the Leica brand. Perfect for photographers who appreciate shallow depth of field and exquisite bokeh, this lens stands out not only for its technical specifications but also for its ability to render images with a unique character.

Build Quality and Design

Right out of the box, the build quality is exceptional. The lens has a solid metal construction that is both durable and visually stunning. The matte black finish lends it a classic aesthetic that complements the Leica M series cameras beautifully. Its compact size, especially for a lens with a maximum aperture of f/1.5, makes it a lightweight option for street photography or portraiture without feeling cumbersome.

The ergonomics are also commendable, with a smooth focus ring that allows for precise manual focusing. The aperture ring clicks positively into place, which gives a satisfying tactile feel when adjusting settings on the fly. One minor point of note is that the lens does lack weather sealing, which might limit its usability in harsh conditions.

Optical Performance

When it comes to optical performance, the Summilux-M 90mm f/1.5 ASPH excels in almost every aspect. The combination of aspherical elements and high-quality glass results in images that are sharp from center to edges, even at wide-open apertures. Chromatic aberration is well-controlled, and color rendition is excellent, producing vibrant and natural-looking images.

At f/1.5, the depth of field is incredibly shallow, granting photographers the ability to achieve stunning isolation of subjects. The bokeh produced is creamy and beautiful, making it perfect for portrait photographers looking for that picturesque background softness that can elevate their work.

Usability in Different Settings

Although it shines in portraiture and low-light scenarios, many photographers will appreciate its versatility in other applications as well. The lens performs admirably in various lighting situations—whether in natural light during golden hour or staged environments with artificial lighting. However, focusing in low-light conditions can be a challenge due to the limited depth of field and the need for precise manual control.

As this lens is primarily designed for the Leica M mount range, its compatibility with other camera systems may be limited. Nonetheless, for those using a Leica M camera, the seamless integration and performance will be well worth it.
