The Leica Elmarit-M 21mm f/2.8 ASPH is a staple in the lineup of wide-angle lenses for Leica M mount cameras. Known for its compact design and impressive optical performance, this lens has garnered a loyal following among both street photographers and landscape enthusiasts.
The Elmarit-M 21mm f/2.8 ASPH strikes a remarkable balance between size and durability. It features a sleek, all-metal construction that not only contributes to a premium feel but also ensures longevity. The design includes a traditional aperture ring and focus scale, thanks to its rangefinder coupling that is vital for precision focusing in street and documentary photography. Weighing in at just 350g, it’s lightweight and easily fits into the photographer's bag without adding much bulk.
When it comes to image quality, the Elmarit-M 21mm f/2.8 doesn't disappoint. It employs aspherical elements to minimize aberrations and deliver sharp images across the frame—even at wide apertures. Color rendition is impressive, providing rich hues and high contrast, making it versatile for various shooting conditions. Distortion is well controlled, a critical aspect for architecture and landscape photography where straight lines matter.
This lens benefits significantly from its compact form factor. It feels well-balanced on both traditional and digital Leica M cameras, which enhances the shooting experience. The manual focus is smooth and precise, making it intuitive to use for photographers who prefer hands-on adjustment. However, the 21mm focal length can be tricky in some situations, especially for those not accustomed to wide-angle perspectives, which may lead to unintentional distortions in framing.
The f/2.8 maximum aperture may not seem particularly fast compared to other lenses in its class, but it performs exceptionally well in low light thanks to its sharpness and contrast. While you can push your ISO given the absence of significant noise, the limitations of f/2.8 could be felt in very dim settings.
In conclusion, the Leica Elmarit-M 21mm f/2.8 ASPH is a stellar choice for photographers who value superb optical quality in a compact form. While it may not cater to every scenario—particularly when it comes to low light or extreme close-ups—the lens's overall performance and build quality justify its place in any Leica M user's kit. Whether you're capturing sprawling landscapes or candid moments on the street, this lens is bound to elevate your photography.
