The Leica APO-Summicron-M 90mm f/2 ASPH is a beautifully crafted lens that embodies the precision and artistry associated with the Leica brand. Designed for the M mount, this lens is a compelling choice for photographers who prioritize image quality, compactness, and versatility in their work.
The optical design of the APO-Summicron-M benefits from advanced technologies, offering a remarkable level of sharpness, contrast, and color fidelity. The use of aspherical elements effectively minimizes distortions and aberrations, allowing for razor-sharp images even at wide open apertures. This lens excels in portrait photography, thanks to its generous 90mm focal length, which provides a flattering perspective while creating stunning background bokeh that makes the subject stand out.
One of the most appealing aspects of this lens is how it performs in challenging lighting conditions. The fast f/2 maximum aperture allows for beautiful low-light shooting, which is particularly advantageous for street photography or event coverage. When shooting wide open, the bokeh is creamy and aesthetically pleasing, providing depth and visual interest to portraits and other compositions.
However, the lens is not without its drawbacks. The price point is steep, typical of high-end Leica glass, which might be off-putting for amateur photographers or those on a budget. Additionally, though the lens is weather-sealed, its all-metal construction makes it slightly heavier than some of its competitors. As a result, extended shooting sessions could become cumbersome without proper handling.
In conclusion, the Leica APO-Summicron-M 90mm f/2 ASPH is prestigious in its class, delivering optical performance that satisfies the rigorous demands of professional photographers. Despite the higher investment and somewhat heavy build, the return in terms of image quality, aesthetic results, and the joy of using a Leica lens is undeniably rewarding. This lens is a great choice for those who are serious about their craft and seek to enhance their photography with one of the best lenses available for the M mount.
