Whois & Analysis for sigmaphoto.com

is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories.

All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan.

Although Sigma produces several camera models, the company is best known for producing high quality lenses and other accessories that are compatible with the cameras produced by other companies.

A digital single-lens reflex camera (also called a digital SLR or DSLR) is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

The reflex design scheme is the primary difference between a DSLR and other digital cameras.

In the reflex design, light travels through the lens, then to a mirror that alternates to send the image to either the viewfinder or the image sensor.

The alternative would be to have a viewfinder with its own lens, hence the term "single lens" for this design.

By using only one lens, the viewfinder of a DSLR presents an image that will not perceptibly differ from what is captured by the camera's sensor.

A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both.

The images may be individual still photographs or sequences of images constituting videos or movies.

The camera is a remote sensing device as it senses subjects without physical contact.

The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface.

The modern photographic camera evolved from the camera obscura.

The functioning of the camera is very similar to the functioning of the human eye.

A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
