Creative image composition with tilt and shift
In photography, tilt and shift are two separate technologies with different effects that are often offered in a joint tilt-shift lens. In the past, these effects could easily be achieved with bellows cameras. The Samyang MF 24mm F3.5 DSLR T/S Tilt-Shift lens offers these two functions in one high-quality lens.
The Shift function compensates for cascading lines. The front of the lens is shifted up or down in relation to the base. This changes the optical path in that the optical axis no longer runs vertically from the sensor through the lens to the front, but from the sensor diagonally through the offset front lens of the front lens section, for example diagonally upwards.
With normal lenses, you would simply tilt the camera upwards for this image section, but this creates the cascading lines - a photographed building appears to tilt backwards. With the shift function, however, the alignment of the sensor (the image plane) remains parallel to the object (the subject plane), only the image axis is tilted. This means that the optics also correspond to those of a "normal" photo. The shift function is often used in landscape and architectural photography to prevent falling lines, but can also be used for portraits.
The tilt function, on the other hand, tilts the focal plane in relation to the sensor plane. The front of the lens is tilted in relation to the base. The optical axis continues to run straight through all the lens elements and the image section changes only slightly in contrast to the shift, but the focal plane is tilted.
With a regular lens, the focal plane is always parallel to the sensor. With a tilt lens, the focus area can be adapted to the requirements of the image. If, for example, a complete train is to be photographed with a shallow depth of field so that the train stands out from the background with a nice bokeh, the photographer can use the tilt function to position the plane of focus along the tracks so that the rear end of the train is not in the blurred area. With a normal lens, he can only do this if he is at right angles to the tracks. The tilt function is also suitable for product shots, paintings or house fronts.
To enable the tilt and shift function in all directions, both the tilt and shift planes can be rotated by up to 90° in 30° increments. This means that the focal plane can also be tilted at an angle or sideways, and the image plane can also be shifted sideways in the tilt function. The entire lens (i.e. tilt and shift) can be rotated to the right, the tilt section to the left.
Miniature effect with tilt and shift
With the tilt function, it is also possible to create the popular miniature effect. To make a subject look like a small model, it is necessary to know why a model looks like a model in the first place.
In three-dimensional vision, the distance between the eyes determines how small the rest of the world is perceived. The further apart the eyes are, the smaller what is seen appears. The greater parallax gives our brain, which is used to our human eye distance, the impression that the rest of the world is getting smaller, as the viewing angle of all objects changes and we can see more of their otherwise hidden sides. This is often used in 3D photography and 3D filming.
However, if you want to achieve a similar effect with just one camera, you use a shallow depth of field instead to suggest that you are looking as a giant at something small and close. To achieve this, the focal plane must be tilted so that the image has two blurred areas. This suggests that the respective sub-area is too close or too far for us "giants" to see it sharply, as we are "concentrating" on the middle area. However, the subject must also be suitable for this manipulation - the photo must ultimately trick the brain.
With a tilt lens, the focal plane is rotated so that it tilts towards the camera (like the screen of a laptop when it is closed) - the front of the lens is tilted upwards. This gives you the look that makes the subject look like a miniature.
The rule of thumb for miniature shots is that they work best from a very elevated position, i.e. looking down at the miniature - like looking at a model. The focal plane must then be tilted parallel to the ground, so the blur must be at the top and bottom, because anything else does not correspond to natural vision and is irritating. Nothing should protrude significantly into the area in focus - huge leaves, the size of soccer pitches, immediately destroy the illusion. Things that protrude out of the focus area, such as electricity pylons or trees, also become blurred, which of course also irritates, as they are actually in the focus area as far as the giant analogy is concerned and should therefore remain sharp.
Portrait photos are less suitable for miniature photography, as the natural human field of vision is landscape format. For artistic effects and creative photography, of course, anything goes. For example, the tilted focal plane can be used to create fascinating portraits in which only the subject's eyes are in focus.
"Tilt, Shift and Focus" with clear controls
The wide-angle lens offers a fixed focal length of 24 mm and a high aperture of f/3.5. 16 coated lenses (including two aspherical and two ED lenses) ensure good image quality. The aperture setting and focusing are manual. The black rotary knobs are used to adjust the optics, both tilt and shift. The gray rotary knobs lock the selected setting to prevent unintentional adjustment.
The entire lens can be rotated using two small, flat, gray release buttons near the bayonet. Both the tilt and shift functions can be rotated separately in 30° increments of up to 90° each. This gives you the freedom to shift not only upright, but also at an angle or sideways, as well as to tilt upright, at an angle or sideways. By combining this range, you can cover any position of the lens in the full circle, but also achieve any desired combination of tilt and shift direction.
Advantages of a full-frame lens on a camera with an APS-C sensor (or smaller)
Save time in post-processing: A large number of lens errors such as distortion, edge blur or vignetting occur on the outer areas of the image. If you use a lens calculated for full format on a camera with an APS-C sensor, these areas are not even used. This ensures maximum quality. Additional post-processing time to correct lens errors is therefore not required.
