The Leica 35mm f/1.4 Summilux-M ASPH (11726) is a full-frame prime lens for the Leica M mount, featuring a 5-group/9-element construction with an aspherical element, 11 aperture blades for smooth bokeh, a 46mm filter thread, and a minimum focus distance of 0.40m — all in a 338g black barrel. The 11726 is the pre-FLE (non-floating-element) ASPH version of the Summilux-M 35mm.

Who is the Leica 35mm f/1.4 Summilux-M ASPH 11726 for?
This lens is made for photographers who want one lens that handles almost everything — and handles it beautifully. At 35mm on a full-frame body, you get a field of view that feels natural and documentary, which makes it a classic choice for street photography and travel. The f/1.4 maximum aperture pulls in light for low-light work, while the 11-blade aperture produces smooth, rounded out-of-focus backgrounds that flatter portrait subjects. At just 338g, it won't weigh down your bag on a day of walking, and it balances naturally on Leica M cameras like the M10 or M11. If you shoot across multiple disciplines and refuse to compromise on optical quality, this lens sits at the centre of what the Leica M system is about. It's manual focus only — no autofocus, no stabilisation — so it rewards deliberate, engaged shooters who enjoy the rangefinder workflow.
Buying a used Leica 35mm Summilux-M ASPH 11726
Picking up this lens second-hand is one of the smarter moves in the Leica ecosystem. The 11726 is a well-established optical design that holds its performance over time — glass doesn't age the way electronics do. Every pre-owned copy on Camera-tweedehands.nl is individually photographed and professionally inspected, and comes with a minimum of 12 months warranty (the exact period is shown on the variant listing). If you're comparing versions, note that the 11726 is the pre-FLE ASPH model — it does not include the floating lens element found in later Summilux-M 35mm FLE variants. Our listing photos document the barrel finish, aperture ring action, and condition of front and rear caps — all three show honest wear history on a used Leica lens.
