Abstract
An adapter having a tilt and shift mechanism which is mounted between a camera body and a photographic lens to relatively tilt or shift the camera body. The photographic lens includes a body mount frame which is provided with a mount to which the camera body can be detachably mounted, a tilt frame which is connected to the body mount frame, and a shift frame which is provided with a lens mounting mount to which the photographic lens can be detachably mounted and which is connected to the tilt frame to linearly move in a direction intersecting the optical axis of the photographic lens. The tilt frame is connected to the body mount frame to move along an arc having a predetermined radius, the center of the radius being located on a center of an image surface.
Claims28
An adapter having a tilt and shift mechanism which is mounted between a camera body and a photographic lens to relatively tilt or shift the camera body and the photographic lens, said adapter comprising:
- a body mount frame which is provided with a mount to which the camera body is detachably mounted;
- a tilt frame which is connected to the body mount frame;
- and,
- a shift frame which is provided with a lens mounting mount to which the photographic lens can be detachably mounted and which is connected to the tilt frame to linearly move in a direction intersecting the optical axis of the photographic lens;
- wherein said tilt frame is connected to the body mount frame to move along an arc having a predetermined radius, the center of said radius being located on a center of an image surface.
An adapter having a tilt and shift mechanism which is mounted between a camera body and a photographic lens to relatively tilt or shift the camera body and the photographic lens, said adapter comprising:
- a body mount frame which is provided with a mount to which the camera body is detachably mounted;
- a tilt frame which is connected to the body mount frame;
- and,
- a shift frame which is provided with a lens mounting mount to which the photographic lens can be detachably mounted and which is connected to the tilt frame to linearly move in a direction intersecting the optical axis of the photographic lens;
- wherein said tilt frame is connected to the body mount frame to move along an arc having a predetermined radius, the center of said radius being located on a center of an image surface;
- and
- wherein said body mount frame comprises a stationary mount frame which is provided with a mount to which the mount of the camera body is detachably mounted, and a rotatable mount frame connected to the stationary mount frame to rotate about an axis normal to the image surface at the center thereof, said tilt frame being connected to the rotatable mount frame.
An adapter having a tilt and shift mechanism which is mounted between a camera body and a photographic lens to relatively tilt or shift the camera body and the photographic lens, said adapter comprising:
- a body mount frame which is provided with a mount to which the camera body is detachably mounted;
- a tilt frame which is connected to the body mount frame;
- and,
- a shift frame which is provided with a lens mounting mount to which the photographic lens can be detachably mounted and which is connected to the tilt frame to linearly move in a direction intersecting the optical axis of the photographic lens;
- wherein said tilt frame is connected to the body mount frame to move along an arc having a predetermined radius, the center of said radius being located on a center of an image surface;
- and
- wherein said shift frame is provided with a securing member which is adapted to secure the shift frame to another member, said securing member being a threaded hole in which a screw of a tripod can be screwed.
