This lens features omnidirectional shifting: 10.4mm to each side, 12mm up and 13mm down. Having the largest shift distance in its class gives it unusual versatility for photography in tight spaces. Rendition of straight lines without distortion is exceptional.
Features: Focus scale in feet and meters, preset aperture can be selected or bypassed by preview slider on mount. Twin sliding dove-tails on the mount permit 10mm of lateral displacement and 12mm of vertical displacement, or equivalent combinations, 15mm wide textured rubber focusin ring.
Olympus' compact and light-weight 35mm f/2.8 perspective-correcting wide-angle ties in well with the traditional compactness, mechanical sophistication and quality optics of the system. Aside from its small size and light weight, this Zuiko's major feature is its double dove-tail slide mechanism. The lens is merely pushed into the desired off-axis positon for perspective correction. There are no knobs to turn or locks to loosen; It's softly but definitely click-stopped in its central on-axis position. Just move it up, down, sideways - even diagonally - until you can see the result you're after in the finder Close manufacturing tolerances and lubricant viscosity hold the lens in any of its possible positions. Exposure of the bearing surfaces to dust and dirt may require periodical relubrication to keep things smooth yet securely fixed when desired. The clever mechanical design of the mount keeps you from pushing the lens beyond its optical limits. It just stops. Another plus: Since the lens barrel does not rotate to move laterally or vertically, the f/stops, distance and displacement indices stay put in their traditional, easy to read, positions.
Unusual in a perspective-correcting lens is the Zuiko's semi-automatic diaphragm. Set the diaphragm as desired; when the lens mount button is pushed in you're at working aperture. Push again and let it pop out and you're wide open for checking focus. This feature is practicularly valuable on an automatic body, like the OM-2 or OM-10, which will set itself to the correct-exposure shutter speed as you stop down.
The convenient diaphragm operation coupled with the f/2.8 aperture and the fast-focusing mount (180° of smooth rotation takes you from infinity to the 1-ft. minimum distance) makes this lens a pleasure to use.
In short, both optically and mechanically, this compact PC lens complements and enhances the entire Olympus SLR system.
By shifting the position of this lens parallel to the film plane, the photographer can correct extreme perspective effects. This unique wide angle lens offers angle coverage similar to the conventional 24mm focal length, with a maximum if 82.7 degrees, as opposed to the normal 63 degrees. Its versatility allows shifting the lens as far as 10.4mm laterally, 12mm rising, and 13mm falling, enabling the photographer to correct the leaning and tilting deformations often found in architectural photography.
Fast full-frame shift lens • Professional model (Top class)
Shift lenses are high-quality lenses, usually wide-angle, that provide a parallel shift facility like the sliding lens panel of professional large-format cameras for correcting converging vertical lines and manipulating the perspective especially for use in architectural and product photography.
Whereas normal lenses designed for 35mm full-frame cameras have an image circle diameter of 43.27mm so that all four corners of the image are inside the image circle, shift lenses provide much larger image circle (60mm or even more). Decentration of the lens is possible within this area.
Vertical shift is the most popular: upward when photographing high buildings, and downward for product shots, so that the camera does not have to be tilted. When the camera is tilted either upward or downward, perpendicular lines are not imaged as perpendicular, but rather converge upward or downward, which is very pronounced in wide-angle shots and can be very irritating.
Genres or subjects of photography (7):
Landscapes • Cityscapes • Buildings • Interiors • Full to mid-body portraits • Street • Travel photography
Adaptation to digital SLR cameras:
Canon EOS SLRs • Sigma SD SLRs • Sony SLRs/SLTs • Pentax SLRs • Nikon SLRs • More information
In order to adapt the lens, the flange focal distance (FFD) of the lens mount must be equal to or greater than the FFD of the camera mount. This lens has the Olympus OM mount with a FFD of 46mm. This is even shorter than the FFD of Canon EOS digital SLR cameras, which have the shortest FFD of 44mm of any modern digital SLR cameras. Therefore, this lens cannot be adapted to any digital SLR camera.

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.
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 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 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),
CF – crop-factor of a sensor,
FL – focal length of a lens.
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 – 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.
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.
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.
The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.
The distance from the front edge of the lens to the subject at the maximum magnification.
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".
The diaphragm must be stopped down manually by rotating the detent aperture ring.
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.
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.
The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.
The aperture setting is fixed at F/2.8 on this lens, and cannot be adjusted.
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.

For lenses with collapsible design, the length is indicated for the working (retracted) state.
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.
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.
Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.
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 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.
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.
