Title: CAMERA AND CONNECTION TOOL FOR CAMERA
Abstract:
 With the present invention, it is possible to easily connect an optical accessory to a camera having an imaging element that cannot be exposed because the lens cannot be removed. A camera-equipped mobile phone 40 is connected via a connection tool 1 to a telephoto lens 30 that is an optical accessory. The connection tool 1 is provided with a base 10 that provides fixation to the camera-equipped mobile phone 40, and a lens tube 20 that provides connection to the telephoto lens 30. A field lens 21A and a focusing lens 21B are fixed inside of the lens tube 20. A connection mount 23 is provided to the distal end of the lens tube 20, and an accessory mount 33 is provided to the base end of the telephoto lens 30. The connection mount 23 and the accessory mount 33 conform to the standard configuration of a C mount. Imaging light from the telephoto lens 30 forms an image at a flange focal distance position X in front of the field lens 21A in accordance with the standard, and the imaging light is sent through the field lens 21A and the focusing lens 21B to the pupil of a camera lens 43 of the camera-equipped mobile phone 40.
