Leica APO-Summicron-M 50mm f/2 ASPH Review
Disclosure: I own the Leica APO-Summicron-M 50mm f/2 ASPH reviewed here. I purchased it with my own funds and am not sponsored by Leica or any other camera or lens manufacturer. All opinions are my own.
In the world of fine optics, there is a legendary status reserved for equipment that doesn’t just perform well but defines a standard. The Leica APO-Summicron-M 50mm f/2 ASPH is exactly that—a lens often cited as the finest 50mm ever made. For photographers looking to transition into the Leica ecosystem, the names can be a mouthful, but the reputation is simple: total optical perfection. I recently paired this lens with the Leica M EV1, a choice driven by a desire to finally experience the “APO” magic without the traditional struggles of rangefinder focusing.
What is the Leica APO-Summicron-M 50mm f/2 ASPH?
Leica APO-Summicron-M 50mm f/2 ASPH is a standard focal length prime lens designed for the Leica M-system. While many 50mm lenses exist, the “APO” (apochromatic) designation signifies that it has been engineered to bring three wavelengths of light into a single focus point, virtually eliminating color fringing.
Build, Design, and Handling
Holding the Leica APO-Summicron-M 50mm f/2 ASPH for the first time, you are struck by how compact it is. Despite its complex internals, it weighs approximately 300g and measures only 47mm in length. It feels like a solid block of brass and glass, epitomizing Leica’s “Made in Germany” quality.
The lens features a built-in, extendable lens hood that operates with a simple twist—a feature I found incredibly convenient compared to clip-on hoods that are easy to lose. The focus ring is buttery smooth, with just the right amount of resistance, allowing for the micro-adjustments necessary when shooting at wider apertures.
In Use on the Leica M EV1
One of the primary reasons I purchased the Leica M EV1 was specifically to use it with the Leica APO-Summicron-M 50mm f/2 ASPH. While the traditional optical rangefinder patch is iconic, it can be unforgiving. The Leica M EV1, with its 5.76-million-dot electronic viewfinder (EVF), changes the game for manual focusing.
Using the EVF allows you to see exactly what the sensor sees. When focusing the Leica APO-Summicron-M 50mm f/2 ASPH, I can use focus peaking or magnification to ensure the subject’s eyes are tack-sharp. This ease of manual focusing removes the “guesswork” often associated with rangefinders, making the shooting experience more relaxed and the hit rate significantly higher, especially when working quickly on the street.
Image Quality
If you are looking for “character” in the sense of soft corners or vintage flares, you won’t find them here. The Leica APO-Summicron-M 50mm f/2 ASPH provides clinical, breathtaking clarity.
- Sharpness: Even at its maximum aperture of f/2, the lens is sharp from the center to the very corners.
- Contrast: The micro-contrast is remarkable, giving images a three-dimensional “pop” that is rarely seen in other lenses.
- Color: Thanks to the apochromatic correction, colors are rendered with absolute fidelity. You won’t see purple or green outlines on high-contrast edges, such as tree branches against a bright sky.
- Bokeh: While it is an f/2 lens (and not a faster f/1.4), the out-of-focus areas are smooth and creamy, thanks to its 11-blade diaphragm.
Who is the Leica APO-Summicron-M 50mm f/2 ASPH for?
This lens is for the photographer who demands the best and has no room for compromise. If you find yourself frustrated by the slight optical flaws of more affordable lenses—like chromatic aberration or soft edges—the Leica APO-Summicron-M 50mm f/2 ASPH is your remedy.
It is particularly suited for:
- Landscape and Architectural Photographers who need corner-to-corner resolution.
- Portrait Photographers who want realistic skin tones and incredible detail.
- Travelers who want a lightweight, “one-lens” setup that provides world-class results.
Final Thoughts
The Leica APO-Summicron-M 50mm f/2 ASPH is more than just a lens; it is a masterpiece of engineering. Pairing it with the Leica M EV1 creates a modern powerhouse that respects Leica’s heritage while embracing the technical advantages of digital focusing.
While the price tag is significant (often exceeding $8,000 USD), it is a “lifetime lens.” For the photographer who wants to stop wondering “what if” and simply start shooting with the best possible optics, there is no substitute for the Leica APO-Summicron-M 50mm f/2 ASPH.
