medium format wide-angle photographic lens brands: PCS, TS-PC, and TS-PC
Super-Rotator MC HARTBLEI 55mm / f=4.5, are for the professional photographer.
The eight-lens optical system is multi-coated (MC) and has anti-reflection
surfaces on the lenses, which improve the quality of the image and increase its
contrast range due to the increased integrated light transmission. In addition,
each lens is hand assembled and carefully checked.
All lenses have a metal housing, no plastics are used. The front lens-casing
surface is deep matte.
Correcting Perspective with the Tilt/Shift Lens
If you photograph architectural subjects with a conventional wideangle 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
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 absolut~ 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
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. Super-Rotator - a mechanism for
adjusting depth of field by tilting the lens in any direction, and the PCS
mechanism is preserved. The direction of the shift can be changed 360 degree and locks at 24 angles. COMPLETE SET: ○
