Camera Body Mount: M42 mount Camera Body. Ideal for architectural photography when controlling perspective. Great for product photography to control depth of field for more appealing shots.
Features include an 11mm shift, 8 tilt and 360 rotating plate which makes it capable to correct perspective distortion that is necessary in interior and exterior architectural photography as well as control depth of field in product photography. You can achieve similar effects and movements of a large format camera with this Tilt/Shift Lens on your SLR or DSLR. This lens's excellent multicoated optics allows you to make sharp, contrasted, color perfect images.
Aperture is controlled manually, the lens can be shifted 11mm from its normal position, and the direction can be shifted 360 and locks at 12 angles. While photographing interiors, still lives, portraits, objects for advertising it often happens that total control of the depth of field is required.With ordinary lenses, it is achieved via the aperture. The most widespread method to increase the depth of field is to minimize the aperture of the lens. However, it frequently happens that this is not possible: when you close the aperture, it is necessary to increase the exposure. In this case, it is hard to photograph objects in motion, or often even is impossible. With the minimum aperture the lens yields a dry unsaturated color image.
Using the lens with TILT feature allows to increase or reduce the depth of field at any aperture. When photographing architectural objects, the distance from the lens to upper and lower parts of the object is different. It would result in a distortion known as a falling building effect (the parallel vertical lines unnaturally come up to one point). Similar problems arise when photographing a model on a catwalk, interiors, sculptures placed on high stands, paintings and architectural details located at an unreachable height. TS lens allows to compensate perspective distortion, to vary the depth of field and zone of sharpness and soften the image if necessary.Multicoated Aperture, focal length, mm: 80. Drawing stroke, mm -1: 50. Focusing scale: 0.6m to infinity. Aperture scale: f2.8 to f22. Shift, mm: 11Tilt: +/- 8.
Weight, kg: 0.95 kg. Focus adjustment: Tilt-shift structure Normally, the relationship between lens and film plane remains constant.
The axis of the lens and the film plane form a 90 angle. The TS 35mm is unique because it is designed to tilt or shift its axis in relation to the film plane. The angle of the lens' axis to the film plane can be changed to either control depth of field thereby increasing sharpness in the image or correct unnatural perspective.
Both tilt and shift movements can be adjusted to work either vertically or horizontally by rotating the lens. The four drawings below illustrate movements with the TS 35mm f/2.8 lens. Figure 1 shows the lens tilted up.
It can also be tilted in the opposite direction. In Figure 2 the barrel has been rotated 90, allowing the tilt to operate horizontally. Figure 3 illustrates the shift movement in the vertical position. Figure 4 shows the lens rotated 90 for horizontal shift movement.
The TS 35mm f/2.8 makes a tremendously important contribution to the versatility of the Canon 35mm system of photography. It enables the photographer to obtain results with a 35mm camera that normally require the use of a large format view camera with its swings and tilts. With the TS 35mm the photographer creates technically correct images of both studio and architectural subjects.
Perspective and depth of field can be controlled to a much greater extent than is possible with conventional lenses. Most 35mm lenses have an image circle just large enough to cover the 35mm film format - about 43mm. The TS 35mm has an image circle measuring 58mm which permits the lens to cover the entire image area even at maximum tilt or shift positions. Correcting Perspective with the Tilt/Shift Lens If you photograph architectural subjects with a conventional wide angle lens aimed up at the building, perspective in the photograph looks unnatural.Lines converge and the building appears to be leaning backwards because the subject and film plane are not parallel to each other. The TS lens provides a solution to the problem. Shifting the lens allows desired framing while keeping the film plane and subject parallel. This also eliminates unnecessary foreground in the process, improving overall composition. This shifting ability can also be used for photographing images in a mirror or window thereby excluding the photographer's reflection. The tilt mechanism allows you to control overall image sharpness. Used in conjunction with aperture, the tilt feature of this lens gives you tremendous depth of field control. This is especially helpful when shooting an object at an oblique angle. For example, let's assume you want absolute sharpness in the foreground and background of a still life scene. First focus on the closest foreground object then tilt the lens until the background also comes into focus. You then make minor focus adjustments, close down the lens to the desired aperture and shoot. Using the tilting mechanism provides an additional means of controlling depth of field and thus allows greater freedom over the aperture and shutter speed combination.
Suppose you want to shoot a long building at an angle with all of it in the best possible focus. Due to the angle between the building and the film plane, foreground and background cannot be rendered sharp simultaneously. Here's where the Scheimpflug principle on which the solution is based comes into play.Imaginary lines must be drawn parallel to the front of the lens and the film plane and a third line from the subject. To attain maximum depth of field, the lens must be tilted so all the lines meet at a point in space. Tilting the lens brings the third line to the point of intersection, increasing the range of sharp focus. Conversely, suppose you want to focus on only certain objects in the middle of a scene, throwing everything else out of focus. In this case focus and tilt the lens so that the subjects are all in the same plane and are parallel. This technique is especially helpful when photographing a product or still life, using the shallow depth of field to emphasize only the central subject. The TS lens could be portraying as a problem solver but it is also capable of taking the images that may challenge your creativity with its optical characteristic.
