If you are looking for the best Leica M lens for your rangefinder, there are a LOT to choose from. In this guide, we run through the full range, explain the benefits of each, and show you the best prices available today.

The combined viewfinder and rangefinder of Leica M series cameras have made them the darlings of many discerning photographers, for over 60 years. Their compact, minimalist designs and almost silent operation make these cameras ideal for street photography, candid portraiture and much more besides. The ethos of compact simplicity extends to Leica’s M-mount lenses, which are typically small and lightweight, yet go extra-large in terms of optical performance.

Leica M-mount lenses are designed to deliver outstanding resolution, contrast, color rendition, structure and tonal depth. The current range is divided into four categories. Primes are split into ‘fast and compact’, ‘high speed’ and ‘classic’ sections, whereas the ‘zoom’ category is currently a class of one, the TRI-ELMAR-M 16-18-21mm.

Leica lenses go by a variety of names. It can be confusing for the uninitiated, but the underlying simplicity is that the names refer to aperture ratings. In ascending order of speed, the Summaron has an aperture of f/5.6, whereas it’s f/4 for the Elmar, around f/3.4 to f/3.8 for the Super-Elmar and f/2.8 for the Elmarit

Ramping things up into ‘high speed’ territory, there’s the f/2 Summicron, f/1.4 Summilux and super-fast f/0.95 to f/1.25 Noctilux.

As a photographic brand, Leica is somewhat legendary for the exacting standards of its German high-tech design and precision engineering. That’s still generally the case but, to get around import tariffs in the USA, some M-mount lenses are now also made in Portugal and are available at reduced prices in the States. Let’s take a look at all of the lenses in the current M-mount line-up.

The combination of an 18mm focal length and f/3.8 aperture rating enables an ultra-wide viewing angle without piling on the pounds, in either weight or cost (at least in Leica terms). The 100-degree viewing angle enables spectacular perspective effects, while the inclusion of an optical element with two independent aspherical surfaces helps to ensure excellent image quality even when shooting wide-open. Distortion is entirely negligible.

If the Elmarit f/2.8 simply isn’t fast enough for your liking, you can step up to this Summicron f/2 lens, which is naturally a whole f/stop faster. It’s not much bigger or heavier, retaining an impressively compact build, although it’s nearly twice as expensive to buy. Again, it has a rectangular metal screw-on lens hood and a protector ring to safeguard the attachment thread when the hood isn’t in use.

Weighing in at just 255g, this lens nevertheless packs in seven optical elements including an aspherical element. The 35mm focal length is a classic choice in street photography, for which handling is up to Leica’s typically impeccable standards. Image quality is razor-sharp, even when shooting wide-open, with beautifully smooth bokeh that remains very good when stopping down a little, thanks to the well-rounded 11-blade diaphragm.

12. Leica APO-SUMMICRON-M 35 f/2 ASPH.

This lens sets a new standard

Specifications
Category: Fast and compact
Elements/groups: 10/5

The APO version of the Summicron 35mm picks up the baton from the regular edition and goes one better in terms of image quality. Optical performance is absolutely incredible in all respects and you can get in really close to subjects, thanks to the 0.3m minimum focus distance, which is much shorter than with other M-mount lenses. It’s still nicely compact and lightweight, but the price tag is hefty.

13. Leica SUMMILUX-M 35 f/1.4 ASPH

The fastest 35mm but not the most expensive

Specifications
Category: High speed prime
Elements/groups: 9/5

Although undercutting the Summicron 35mm f/2 lens for price, this one has a faster f/1.4 aperture rating that makes it arguably more versatile in low-light photography and anytime you want a really tight depth of field. It can’t focus as close as the f/2 lens but, even so, the floating elements behind the diaphragm blades ensure image quality remains outstanding at short focus distances.

50mm primes

How much sharpness do you really need? If the answer is ‘all you can get’ for making the most of the latest high-resolution Leica M cameras, this lens is the top choice for a standard prime. With APO (Apochromatic) credentials, it also keeps chromatic aberrations to an absolute minimum. The quality of the construction and the images that it delivers are absolutely stellar, but it’s very pricey to buy.

As in the 35mm camp, the big money is on the APO Summicron lens whereas this faster Summilux has an f/1.4 aperture that makes it more ideal for low-light photography and gaining a tighter depth of field, helping to isolate the main subject within a scene. Again, it gives an entirely natural viewing perspective and delivers sharp, high-contrast images even at its widest aperture setting.

This is a bit of a heavyweight for a Leica M-mount lens, weighing in at 700g, but with god reason. It has a mighty aperture rating of f/0.95, making it one of the fastest lenses in the world. Indeed, it’s the fastest lens on the planet that features an aspherical element. Not only does it produce an incredibly tight depth of field, but Leica says that light from a single candle can be sufficient for handheld photography.

A highly versatile short telephoto lens, this Summicron 75mm works well for shooting nature and landscapes as well as for portraiture. The f/2 aperture rating enables a tight depth of field although, in this respect, it naturally can’t compete with the Noctilux 75mm. Even so, image quality is fabulous in all respects, it’s less than half the weight of the Noctilux and only about a third of the price.

A truly versatile optic, the Macro-Elmar works really well for general shooting when you’re out and about and need a telephoto focal length to get you closer to the action. Unusually for a ‘macro’ lens, it has a fairly lengthy minimum focus distance that only enables a 0.15x maximum magnification factor. However, couple it with the Leica Macro-Adapter-M and you can halve the shooting distance, boosting macro magnification to 0.5x or 1:2.

An amazing portraiture lens, the 90mm f/1.5 combines scintillating sharpness, contrast and color rendition even when shooting wide-open, along with a really tight depth of field and a sumptuous softness for defocused areas. Indeed, the minimum depth of field and the overall aesthetic of image rendering are a very close match to those of the similarly priced NOCTILUX-M 75 f/1.25 ASPH. You’ll need deep pockets, however, as it’s one of the very most expensive M-mount lenses on the market.

Topping the M-mount range in terms of telephoto reach, this lens really covers the distance. It’s brilliant for compressing perspective and for anytime you can’t get as physically close as you might like to the subject you’re shooting. It also works really well for tight head-and-shoulders portraits, enabling you to shoot from a comfortable distance. As you’d expect, image quality is exemplary in all respects.
