Manufacturer description #1

This lens possesses the same focal length and speed of the ELMAR 135mm f:4.5. Its design, however, is somewhat different, as it incorporates an astonishing color-correction and flatness of field. The ultimate in a telephoto lens for the LEICA.

Manufacturer description #2

Hektor 135mm., f/4.5 (5 3/8"), angle 18 deg., constitutes a triplet variant with a converging cemented surface inserted in the central member. This cement surface is an additional source of important correction possibilities which have been extensively used in this objective. The general correction is therefore excellent and the performance outstanding.

Maximum resolution capacity combined with perfect contrast are the qualities which make this objective particularly suitable for photographs requiring sharp rendition of finest structural details. For the rest, it meets all the requirements demanded of a good distance objective. The performance of the system is excellent at full aperture, so that reduction of the aperture is necessary only when increased depth of focus seems desirable. In a special short mount, it can be used with the Mirror Reflex Housing.

Manufacturer description #3

The Leitz Hektor 135mm. (5 3/8"), F:4.5 lens has an exceptionally high resolving power and should be used where subjects of fine structure are to be photographed. It fulfills perfectly all that the photographer demands for a long-focus lens, being suitable not only for distant landscapes and scientific work, but also of great value for portraits-particularly head studies-and for fine details of architecture, which must necessarily be photographed from some distance. In addition, the 135mm. Hektor lens has extremely good color correction, and is thus particularly fitted for work with color films, and for use with infra-red films and a red filter.

Manufacturer description #4

A very versatile lens, with which the picture area can be filled from an even greater working distance than with the 90mm lens. Its special value is in sports photography, in recording fine detail in architecture, and in photographing people and animals from a distance unobserved. Distance is brought near, and foreshortened perspective can give surprising pictorial effects.

From the editor

Coated from No. 590551 (1946). International aperture scale instead of European from 1947. Vulcanite trim was added to the non-rotating base part of the mount in 1949. All chrome version with vulcanite trim was introduced in 1950.

According to the General Catalogue (July 1977), lenses with serial numbers up to 1,416,000 use A36 filters while lenses from No. 1,416,001 use E39 filters.

The lens hood FISON / 12510 is listed as suitable for this lens in the "Leica: The camera of modern times" booklet (PUB 1244 - 4th ed. W-11-36-CC).

Typical application

portraits, distant subjects, distant landscapes with perspective compression effect, travel

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.

Sorry, no additional information is available.

FISON / 12510 (1925-1963)

The first Leica hood, for the ELMAR 5cm. In its earliest form it had a simple push-on fit and a rectangular opening at the front. The hood was black and there was an index line on the front part of the barrel to re-align the hood after focusing the lens. By 1933 the opening was round, thus eliminating the need to re-align after focusing. By 1935 the hood had assumed its familiar form with the clamping ring and screw. It was available black or chrome and a chrome version was made by Leitz, New York, and engraved as such. There are many minor variations.

FISONCHROM

Same as FISON but chrome finish.

IUFOO / 12575 (1956)

Introduced for ELMAR 90mm and HEKTOR 135mm. Double trigger fastening. Early version had narrow chrome band and was engraved on the black portion "Elmar 9cm Hektor 13.5cm". Later version had wide chrome band carrying the above engraving. Later still engraving was: "1:4.5/135 1:2.8/90 12575N 1:4/135 1:4/90". Final version was all black.

FIKUS / 12530 (1933-1965)

Extendable hood for lenses of focal length 3.5cm to 13.5cm. Outer black sleeve slid over the nickel or chrome graduated sleeve and was locked in position by a set screw. The black lower collar carried the usual clamping ring and screw. Early ones nickel inner sleeve, later ones chrome. Leitz, New York also made an all chrome version. Many variations in engravings: e.g. four focal lengths 13.5cm, 9cm, 5cm and 3.5cm with "Hektor" to the left and "Elmar" to the right of the scale; three focal lengths only with no 3.5cm and only "Elmar" to the left; 13.5, 9 and 5 with two positions for the 5, the lower one having "Hektor" to the left and "Summar" to the right.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

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 can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

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.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

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. For example, 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".

Electromagnetic diaphragm control system

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

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

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.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
