Leica's compact 50mm f/2.4 built for daily M-system carry
The Summarit-M 50mm f/2.4 ASPH sits at an interesting point in Leica's lens lineup: lighter and smaller than the Summicron, but optically serious. At 190g and just 33mm long, it disappears into a coat pocket with a M body attached. The 46mm filter thread keeps it slim, and the anodized barrel handles daily use without fuss.
The 6-element, 4-group design uses high-refraction glass with anomalous partial dispersion to control chromatic aberration across the frame. Nine aperture blades give smooth out-of-focus rendering at f/2.4, and the aperture ring stops down to f/16 for precise exposure control in bright conditions. Six-bit coding communicates lens data directly to digital M bodies, letting the camera apply appropriate corrections automatically. The 0.8m minimum focus distance is standard for M-mount 50mm lenses, keeping the optical formula clean than engineering around close-focus compromises.
For M-system photographers who want a 50mm they can carry every day without treating it like a museum piece, the Summarit-M makes a straightforward case for itself.
Who It's For
Street photographers working long days on foot will appreciate the 190g weight and compact 33mm length, which keeps a M body pocketable and inconspicuous. Travel photographers who shoot mixed conditions benefit from the six-bit coding on digital M bodies, which triggers automatic lens corrections without manual input. Rangefinder shooters transitioning from film to digital M systems get a lens that communicates natively with modern Leica bodies. Mirrorless photographers on Sony E, Nikon Z, or L-Mount systems using an adapter gain access to Leica M glass with manual aperture ring control intact.

FAQ
- How does the Summarit-M 50mm compare in size to Leica's Summicron-M 50mm f/2?
- The Summarit-M is measurably more compact at 190g and 33mm long versus the Summicron's heftier build. You're trading maximum aperture (f/2.4 vs f/2) for pocket-friendly dimensions and weight that won't wear on your neck during all-day carry.
- Does this lens have autofocus?
- No. The Summarit-M is manual focus only, typical of M-mount lenses. Full-time manual focusing is standard, so you can adjust focus at any aperture without clicking between modes.
- What does the six-bit coding do?
- It communicates lens metadata to digital M bodies like the M10 or M11, allowing the camera to apply lens-specific corrections automatically. Film shooters won't notice a difference.
- How close can you focus with this lens?
- 0.8 meters minimum focus distance. That's standard for M-mount 50mm lenses and means Leica didn't compromise the optical formula to enable closer focusing.
- Is the Summarit-M weather-sealed?
- No weather sealing. The anodized barrel resists corrosion and handles daily use, but it's not designed for sustained rain or salt spray.
- What filter size does it take?
- 46mm filters. The slim barrel keeps the thread diameter down, which contributes to the overall compact profile.
- How many aperture blades does it have?
- Nine blades. That's enough to render out-of-focus areas smoothly without the polygonal harshness you'd get with fewer blades.
