" .... OLYMPUS 35mm f/2.8 ZUIKO SHIFT LENS One if the REALLY NICE aspects of the Olympus Camera System is that they make a WIDE ARRAY of 'Bits & Pieces' for specialized applications, from the more mundane to the most exotic. If you NEED Perspective Control, as in Architectural Photography, this is the ONLY WAY to get in in 35mm format! This example is in NICE CONDITION, but the barrel of the lens is just starting so show some light wear on the high spots. Still quite clean though, I'd call it E+ and I grade conservatively. The glass is BEAUTIFUL, not a speck of hazing or fungus, CRYSTAL CLEAR. The focus is as SMOOTH as butter, and the preset manual apertures work EASILY; the lens shifts smoothly with a CRISP DETENT at the center position. Overall, an EXCELLENT EXAMPLE of this SCARCE, DESIRABLE lense..." - BIGleo -

Zuiko Shift 35mm f/2.8 (PC) wideangle lense

This lense type was first introduced by Nikon in 1962 (
PC-Nikkor 35mm f/3.5 Preset), the ZUIKO equivalent was probably introduced in 1976 (where an early Olympus OM-2 instruction manual indicated there will be a SHIFT lense available soon in ZUIKO lense development program for OM system). Basically, this special lense type features perspective control ability - to be more exact, they are wide-angle lenses with extended film plane covering ability. These lenses are used to covers large rectangular subjects, for example, a tall building, the photographer has to tilt his camera upwards to include the top of the structure; generally, the resulting image portrays in the photograph will have walls of the building appear to converge, as if the building were falling over backwards. The eventual visual effect of a typical shooting situation is quite apparent with the use of conventional lenses. The principle is quite similar to large format view cameras with swings and tilts with movable lens board features where you can actually be able to play around depth of field or correcting perspectives but in the case of ZUIKO SHIFT lenses, it is more confined to manipulation in perspective rather than depth of field. Basically, such lense type replicates view camera's perspective control feature into a small 35mm format. With a ZUIKO SHIFT optic, the photographer is able to shift the lens horizontally, vertically or diagonally to include the top of the building while keeping the film plane parallel to the wall surface to eliminate unwanted converging lines. Naturally, without other mechanism such as flexible swing control and lens board etc. as provide in large format cameras, depth of field control with these 35mm lenses is still has to fall back to selective use of apertures. Further, this series only offer SHIFT feature but DOES NOT offer TILTING control, the only such lense type was only be found in the discontinued Canon FD system ( FD TS 35mm f/2.8 SSC) and revised with the more recent EOS's EF TS-E series.

Well, technically other than making use of these specialized lenses for perspective control, there are other ways to minimize effect of converging perspectives when a normal lense type is used; for an instance, by using a wideangle lense to shoot but you have to compromise with loss of useful negative space with inclusion of large unwanted foreground in a picture while use cropping to eliminate undesirable elements in a wide-angle negative (or another way is to use some "engineering work inside a darkroom" to compensate such effect). But unfortunately, 35mm format has a far less negative size as compared to any typical view cameras (4 x 5 or 8 x 10) which you can afford to do so with cropping the big negative(s). So, these dedicated PC lenses preserves the little film size the 35 x 24mm it has in order to optimize the image for desktop publishing etc.

" ... This is an exercise in perspective correction on a budget: not having a PC lens available, this was shot with a (very sharp) 20mm/2.8 Spiratone wide angle lens, and the extra stuff at the bottom was cropped out...." - Rick Oleson - Image downloaded from COLOR of RICK website.

In operation, this ZUIKO special application wideangle lense features an omni directional shifting: 10.4mm to each side, 12mm up and 13mm down. Due to its shifting and rotating mechanism (the shift feature and the fact that a PC lens can be rotated 360' to allow shifting in any direction, the lens thus, has no automatic features), a distinctive feature found in this lens type is, the diaphragm has to be preset* manually and used with stop-down metering (this is not an important issue as in most cases, shooting successful pictures with a PC lense often takes time to setup, the lack of automatic feature although is undesirable but may not be an absolute disadvantage factor. Overall, it is a solution-providing optical lense in 35mm photography). Naturally, the distinctive feature of perspective control lens type can also be used for shooting interiors and even for arranging product shots inside a studio. When perspective correction is not required. Besides, these series of lenses may also be used as a conventional medium wideangle lens to provide equally excellent optical results except there is a little inconvenience in metering. With these lenses, you may also take advantage of the shifting movements of the ZUIKO SHIFT to make panoramic pictures by joining two exposures. Its advantage over an ordinary lens mounted on a panoramic equipment is that it is able to maintain the film plane parallel to the subject at all times, and hence, the pictures will match perfectly.

Generally, the apparent convergence of vertical lines, say in a picture of a tall building, is the result of the correct geometrical perspective of the subject as seen by even the best quality lenses. This is because these lines are not on the optical axis of the lense. To handle pictures which have a considerable number of vertical lines, a general rule to follow is to place the camera in a position about half way between the top and bottom of the subject with the camera pointed horizontally. Use of a wideangle lens, although intended for such photography, could present a distorted picture, too, if the camera-lens position is off the axis. If it is impossible to correct the situation by moving the camera-lens position, then such SHIFT (PC) lenses, with rising and falling front objective, are an ideal solution to the problem of convergence of parallel vertical lines. This movement of the lens is similar to the swinging back of many larger view cameras.

How a Perspective Control (PC or SHIFT) lense overcomes perspective distortion

As long as the film is in the vertical plane - the camera held parallel to the subject - there is no perspective distortion. But shooting in this position with a conventional lens frequently produces unbalanced* composition. When photographing a tall building, for instance, the top of the building is cut off, and unwanted foreground is included because the camera is usually held close to the ground level (fig. 1). To include the top of the building and reduce the foreground, the camera must be tilted, but this results in converging vertical lines (fig.2). Similar distortions result in horizontal lines when photographing a long line of buildings with the camera tilted.

However, with the ZUIKO SHIFT's unique mechanism that enables shifting and rotating movements, it permits the photographer to get balanced composition without tilting the camera. The film plane will remain vertically while the center of the lens is placed on the line connecting the center of the subject with that of the film (fig.3). Theoretically, the converging verticals would be acceptable in terms of the perspective that is true to life. But the human eyes will not psychologically accept such vertical convergence while it is quite prepared to accept the same effect in the horizontal plane. The use of slow shutter speed(s) is a common element during operation as it is not advisable to shot these lenses at their widest apertures so a steady tripod is a handy supplementary accessory.

Having one of the largest shift distance in its class gives it unusual versatility for photography in tight spaces. Rendition of straight lines without distortion is exceptional. The Zuiko family has a total of two such specialized lenses which enable tilt and shift movement for perspective control. Both Zuiko 35mm f/2.8 SHIFT and another equivalent lense type with a wider wideangle view, Zuiko 24mm f3.5 SHIFT have long been enjoying a fine reputation in optical excellence and innovation. The Zuiko 24mm SHIFT lense was introduced quite late in 1984 as part of the general Zuiko lense updating program aim to supplement the various OM-3(Ti) and OM-4(Ti) series bodies further with choice and varieties of lense types in the ever expanding MF Zuiko lense family during the '80.

Basically, the lens can be moved parallel to the film plane. When you 'shift' the PC lense, you can shoot subject where you would otherwise tilt the camera as with the bellow used in the large format cameras, but a physical 35mm lense is not flexible as a bellow unit, and by doing so, it will inevitably leads to converging lines. Like most 35mm type shift lenses (Some called it "PC" for Perspective Control, while some selective types with additional were called "TS" (Tilt and Shift) lenses), the shift is guided by a track with scales for fine adjustment by precision gearing, usually it is scaled with millimeter. It can either be moved up or shift horizontally and use to cover the entire image circle formed within the 24 x 36mm format. Thus, it can, theoretically adjust and manipulate to a certain extend, a small degree of depth of field which makes it as ideal lens for indoor still life and for architectural photography.

Zuiko PC-SHIFT lenses are preset type and do not have any automatic diaphragm, which means i.e., the lense must be set manually to the required taking aperture for correct light reading and exposure (stopped-down* metering). Full aperture should only be used for focusing, picture composing and as well as checking sharpness BEFORE such lense is shifted as it will provide a bright viewfinder image in order for you to perform those tasks. To take perspective-corrected pictures: 1) set the camera so that the film plane is aligned parallel to the subject, 2) stop down the lense and determine exposure, 3) compose by shifting the lense, and release the shutter. The correct way of determibe correct exposure is by (After stopping down the lense but BEFORE using the shift): i) with an OM-1(n) or OM-2(n) on MANUAL MODE Align the meter needle to the center of the exposure index by adjusting the shutter speed ring and aperture ring. ii) The TTL exposure meter of the OM-1(n) and OM-2(n) indicates correct light readings at zero-shift (normal position); i.e., when the optical axis of the lens is perpendicular to the film plane at the center of the picture area. Determining exposure after shifting the lense may result in incorrect exposures. With OM-2(n) or equivalent OM bodies on AUTO MODE: i) The shutter speed (corresponding to the preset aperture for proper exposure) is indicated by the meter needle. Make sure the needle does not enter the red zone (beyond 1/1000 sec.). Olympus recommends use of 1:10 (checker matte) focusing type which they claimed was specially designed for this lense type.

Always select smaller apertures such as f/11, f/16 or f/22 are always recommended in order to ensure the maximum depth of field can be achieved. The Zuiko 35mm SHIFT lense uses popular OM standard 49mm screw-in filters. It has a lesser picture coverage than the 24mm OM SHIFT counterpart with 83° maximum shift instead of 100°. But it is far lighter and very compact in size as it weighs merely 310g as compared to the Zuiko 24mm SHIFT lense's 510g !

* STOPPING DOWN THE LENSE. Press the depth of field preview button which locates at the side of the aperture ring (lense section) the button will lock in place closing down the iris diaphragrn to the preset aperture. (To reopen the Iense, return the button to the original position by pressing down again and releasing.)

In terms of cost, the 35mm SHIFT lense has a more reasonble entry price between USD740.00-825.00 (new) while mint at used condition may be between USD450.00 - 400.00 while the comparing ultra-wideangle 24mm Zuiko SHIFT is retailing at a ridiculous price between USD950.00 - 1500.00 ! Lastly, although this is a different breed of optic which originally is designed as a special application lense to serve professional applications but still, I would like to add a word of caution, as this lense demands manual operations all the way - which includes exposure measurement which may require experience other than simply relying on the camera metering system. Which means SHIFT lenses are not as easy to handle as you thought it should be and in fact, it is quite tedious in setting up for shooting as well, unless your profession calls for such needs, saved some of your money, invest into a prime wideangle lense can be a more practical measure for day to day photography.
