With its extensive focal range, consistent maximum aperture of f/2.8, and vast scope of uses, this new addition is a shining example of a lens that can be enjoyed by professionals, enthusiasts and first-time SL-System adopters alike. As a bundle option with the SL2 and SL2-S, the SL-System now becomes an even more viable option for all kinds of users to realize their creative passions.

The elaborate Vario-Elmarit-SL 24-70 f/2.8 ASPH. lens design ensures an outstanding optical performance as it is comprised of 19 elements in 15 groups, featuring three elements with aspherical surfaces on both sides. This sophisticated lens also offers an outstanding ability to provide correction of chromatic aberrations across the entire focal range, resulting in a crisp photograph no matter where you zoom. The internal focusing is based on a single, lightweight lens element, and utilizes a silent stepper motor to deliver a fast and precise autofocus. In addition to its lightweight design, the metal body and weather sealing make the Vario-Elmarit-SL 24–70 f/2.8 ASPH durable in any environment, ultimately making it suited for even the rigors of outdoor landscape and adventure photographers or the hustle and bustle of a pro wedding photographer.

The compact dimensions of the Vario-Elmarit-SL 24–70 f/2.8 ASPH. are made possible by the omission of in-lens optical image stabilization. When the lens is mounted on the SL2 or SL2-S, the camera’s stabilized image sensor steps up to the task with highly effective image stabilization while affording the lens its smaller size and lower weight. This makes the Vario-Elmarit-SL 24–70 f/2.8 ASPH. the ultimate tool for both still photography in low-light and video recordings with rock-solid dynamic camera movements. The aperture of the Vario-Elmarit-SL 24–70 f/2.8 ASPH. comprises 11 blades that create a consistently lovely, circular bokeh to make subjects stand out and pop from the background, while its minimum focusing distance ensures exceptionally high-quality images even when shooting at close range. From near to far, low-light to broad sunlight, portraits to fast action, 24 to 70 mm, the new addition to the L-Mount portfolio enables photographers to capture any kind of photo with top-level sharpness and the Leica look.

Supplementing the launch of the Vario-Elmarit-SL 24-70 f/2.8 ASPH. lens are two camera and lens bundles, offering the latest of the SL-System at a more approachable price when purchased as a set. Choose either the high-megapixel flagship SL2 or the jack-of-all-trades hybrid SL2-S along with the new 24-70 lens for an even further value proposition, enabling photographers or videographers to pursue their path to creative freedom.

Manufacturer description #2

With its universal focal range, consistently high aperture and closest focusing distance of just 18 cm at a focal length of 24mm, the Vario-Elmarit-SL 24–70 f/2.8 ASPH. is suitable for video and still photography applications across the board. It is a perfect choice for photographers with a preference for travelling light.

In still photography as well as video recordings, the Vario-Elmarit-SL 24–70 f/2.8 ASPH. delivers a consistently high speed of f/2.8 at every focal length from the wide angle to the short telephoto end. Thanks to its great versatility and compact, ergonomic construction, the lens enables a fast response to any shooting scenario without the need to change lenses.

The elaborate optical construction of the Vario-Elmarit-SL 24–70 f/2.8 ASPH., featuring six aspherical surfaces, guarantees excellent imaging performance throughout the entire zoom range. The eleven-bladed aperture and perfect chromatic correction ensure an especially harmonious bokeh and endless compositional possibilities.

With a body and lens hood made entirely of metal, the Vario-Elmarit-SL 24–70 f/2.8 ASPH. is a robust companion for any situation. Weather-sealing ensures that the lens is well protected against water spray and dust – so that even harsh environmental conditions will not hamper your photography or video project.

Quiet, fast and precise: these are the attributes that characterise the autofocus of the Vario-Elmarit-SL 24–70 f/2.8 ASPH. The fast stepper motor moves only a single, very light-weight lens element – resulting in a virtually lag-free autofocus operation. This not only applies when the lens is mounted on a Leica SL, SL2 or SL2-S, but also in combination with any other camera equipped with an L-Mount bayonet.

The optical system of the Vario-Elmarit-SL 24–70 f/2.8 ASPH. contains a total of 19 elements in 15 groups. These include three aspherical lens elements for the correction of monochromatic aberrations and nine elements made from glasses with anomalous partial dispersion for the correction of chromatic aberrations.

From the editor

The optical design of the lens is identical to the Sigma 24-70mm F/2.8 DG DN | A. The Leica lens differs from Sigma in the absence of both focus mode selector and zoom lock.

It should be noted that this is not the first case of collaboration between these companies: the Leica Vario-Elmar-R 28-70mm F/3.5-4.5 introduced in 1990 was also a Sigma design.

Typical application

landscapes, interiors, buildings, cityscapes, portraits, photojournalism, weddings, parties, carnivals, live concerts, travel

Model produced in a small batch. It is collectible and can only be found on the secondary market.

Unique Leica Look

Leica lenses are one-of-a-kind optical masterpieces that are impressive because of their unique Leica Look. This is ensured through exceptional optical design combined with selected materials and the highest quality standards.

Leica lenses reveal their full potential only when mounted on Leica cameras, since only these have sensors precisely matched to their optical characteristics.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film. The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Stepping motor

Aspherical elements

Aspherical elements (ASPH, XA, XGM) are used in wide-angle lenses for correction of distortion and in large-aperture lenses for correction of spherical aberration, astigmatism and coma, thus ensuring excellent sharpness and contrast even at fully open aperture. The effect of the aspherical element is determined by its position within the optical formula: the more the aspherical element moves away from the aperture stop, the more it influences distortion; close to the aperture stop it can be particularly used to correct spherical aberration. Aspherical element can substitute one or several regular spherical elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Use of aspherical elements has its downsides: it leads to non-uniform rendering of out-of-focus highlights. This effect usually appears as "onion-like" texture of concentric rings or "wooly-like" texture and is caused by very slight defects in the surface of aspherical element. It is difficult to predict such effect, but usually it occurs when the highlights are small enough and far enough out of focus.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Canon's Super UD, Nikon's Super ED, Pentax' Super ED, Sigma's FLD ("F" Low Dispersion), Sony' Super ED and Tamron's XLD glasses are the highest level low dispersion glasses available with extremely high light transmission. These optical glasses have a performance equal to fluorite glass.

High-refraction low-dispersion elements

High-refraction low-dispersion elements (HLD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

High Index, High Dispersion elements

High Index, High Dispersion elements (HID) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Anomalous partial dispersion elements

Anomalous partial dispersion elements (AD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Fluorite elements

Synthetic fluorite elements (FL) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. Compared with optical glass, fluorite lenses have a considerably lower refraction index, low dispersion and extraordinary partial dispersion, and high transmission of infrared and ultraviolet light. They are also significantly lighter than optical glass.

According to Nikon, fluorite easily cracks and is sensitive to temperature changes that can adversely affect focusing by altering the lens' refractive index. To avoid this, Canon, as the manufacturer most widely using fluorite in its telephoto lenses, never uses fluorite in the front and rear lens elements, and the white coating is applied to the lens barrels to reflect light and prevent the lens from overheating.

Short-wavelength refractive elements

High and specialized-dispersion elements (SR) refract light with wavelengths shorter than that of blue to achieve highly precise chromatic aberration compensation. This technology also results in smaller and lighter lenses.

Blue Spectrum Refractive Optics

Organic Blue Spectrum Refractive Optics material (BR Optics) placed between convex and concave elements made from conventional optical glass provides more efficient correction of longitudinal chromatic aberrations in comparison with conventional technology.

Diffraction elements

Diffraction elements (DO, PF) cancel chromatic aberrations at various wavelengths. This technology results in smaller and lighter lenses in comparison with traditional designs with no compromise in image quality.

High refractive index elements

High refractive index elements (HR, HRI, XR etc) minimize field curvature and spherical aberration. High refractive index element can substitute one or several regular elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Apodization element

Apodization element (APD) is in fact a radial gradient filter. It practically does not change the characteristics of light beam passing through its central part but absorbs the light at the periphery. It sort of softens the edges of the aperture making the transition from foreground to background zone very smooth and results in very attractive, natural looking and silky smooth bokeh.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance from the lens mount to the film or sensor can also be different.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. A magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size". A lens is not considered to be "true" macro unless it can achieve at least life-size magnification.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Electromagnetic diaphragm control system

Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.

Convex protruding front element

The convex front element protrudes from the lens barrel, making it impossible to use filters.

Fixed focus

There is no helicoid in this lens and everything is in focus from the closest focusing distance to infinity.

Overall linear extension

The entire lens optical system moves straight backward and forward when focusing is carried out. This is the simplest type of focusing used mainly in wide-angle and standard prime lenses. It has the advantage of introducing relatively little change in aberrations with respect to change in focusing distance. With telephoto and super telephoto lenses this method becomes less beneficial in terms of operability because of the increased size and weight of the lens system.

Front group linear extension

The rear group remains fixed and only the front group moves straight backward and forward during focusing. This method is primarily used in zoom lenses and allows to design comparatively simple lens construction, but also places restrictions on zoom magnification and size reduction.

Front group rotational extension

The lens barrel section holding the front lens group rotates to move the front group backward and forward during focusing. This method of focusing is also used only in zoom lenses.

Internal focusing (IF)

Focusing is performed by moving one or more lens groups positioned between the front lens group and the diaphragm.

Methods of internal and rear focusing have the following advantages:

Rear focusing (RF)

Focusing is performed by moving one or more lens groups positioned behind the diaphragm.

Methods of internal and rear focusing have the following advantages:

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Rotary zoom

The change of focal length is achieved by turning the zoom ring and the manual focusing - by turning the separate focusing ring.

Push/pull zooming allows for faster change of focal length, however conventional method based on the rotation of the zoom ring provides more accurate and smooth zooming.

Push/pull zoom

The change of focal length and the manual focusing is achieved by one and the same ring. The change of focal length happens when the photographer moves the ring towards the mount or backwards and the rotation of the ring leads to change of focus.

Push/pull zooming allows for faster change of focal length, however conventional method based on the rotation of the zoom ring provides more accurate and smooth zooming.

Zoom lock

The lens features a zoom lock to keep the zoom ring fixed. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.

Power Zoom

The lens features electronically driven zoom mechanism. It provides smoother, more natural zoom movements than you could accomplish by hand.

The Holy Trinity of lenses

The Holy Trinity of lenses refers to a three-lens set that covers a focal length range from the ultra-wide focal length of 14-16mm all the way long to the telephoto focal length of 200mm. The set typically consists of a 16-35mm ultra-wide angle zoom lens, a 24-70mm standard zoom lens and a 70-200mm telephoto zoom lens and usually represents the best constant-aperture zoom lenses in a manufacturer's lineup. The set is designed to cover almost every genre of photography, be it landscapes, architecture, portraits, weddings, sports, travel or even wildlife (with teleconverter). However, it is also expensive, large and heavy.
