One kind of camera that doesn’t employ a reflex mirror is the digital still camera (DSC), which includes the Sony DSC cameras. Due to their affordable pricing and good quality, DSCs, which resemble point-and-shoot cameras, are the most popular kind of cameras.[Reference required]
These are some DSCs:

DSLT cameras, or fixed semi-transparent mirror cameras, are single-lens cameras that do not have a moving reflex mirror like a traditional DSLR. Examples of these cameras are the Sony SLT cameras. A mirror with some transparency transmits As with reflex mirrors in DSLR cameras, part of the light is sent towards the image sensor and some is reflected along the way to a pentaprism or pentamirror, which subsequently directs part of the light toward an optical vision finder (OVF). Just a portion of the light takes one path while the remainder takes a different one; the total amount of light remains unchanged. As a result, DSLT cameras need to shoot one half stop differently from DSLR cameras. One benefit of utilizing a DSLT camera is that it eliminates the blind spots that DSLR users get when moving the reflecting mirror to direct light onto the sensor rather than the viewfinder. Because light always travels, there is never a time when it does not DSLT cameras benefit from continuous auto-focus tracking along both tracks. This is particularly helpful for tracking when shooting video and for burst-mode photography in low light.[Reference required]

primary article Digital rangefinder with a rangefinder camera
A rangefinder is a tool used to estimate the distance between subjects so that the objective lens of a camera can be focussed appropriately (open-loop controller). It is possible for the rangefinder and lens focusing mechanism to be disconnected. The phrase “rangefinder camera” is used extremely narrowly in everyday speech to refer to manual-focus cameras having an optical rangefinder that uses parallax to read out visually. The majority of digital cameras use an analysis of the image taken by the objective lens to focus, and any distance calculation that is offered is just a consequence of the focusing procedure itself (closed-loop controller).[65]

An Alkeria Necta N4K2-7C line scan camera with a shutter speed of 250 microseconds, or 4000 frames per second, was used to capture an image of a San Francisco cable car.
Traditionally, a line-scan camera uses a single row of pixel sensors rather than a matrix.
among them. A computer receives the lines continually and connects them to create an image.[66][67] The most popular method for doing this is to attach the camera output to a frame grabber that is housed in an industrial computer’s PCI slot. Before sending the picture to the computer software for processing, the frame grabber serves as a buffer and occasionally does some processing. Digital line-scan devices are widely used to measure height and width for industrial processes.[68]
To create colored images or to boost sensitivity using TDI (time delay and integration), many rows of sensors can be employed.
A broad field of view is necessary for many industrial applications. It has historically been quite challenging to maintain uniform illumination throughout vast 2D regions. All using a line scan camera
all that is required is to provide uniform lighting throughout the “line” that the camera is now viewing. This captures sharp images of moving things in front of the camera.
These kinds of cameras are also frequently employed in picture finishes, which identify the victor when several competitors cross the finish line almost simultaneously. They can also be employed as industrial tools for quick process analysis.
Additionally, line-scan cameras are often utilized in satellite imagery (see to push broom scanner). The sensor row in this instance is oriented perpendicularly to the direction of the satellite’s motion. Scanners frequently use line-scan cameras. The camera shifts horizontally in this instance.

Digital superzoom cameras are those with extremely long magnification. People who are nearsighted can use these superzoom cameras.
The HX series comprises Sony’s superzoom cameras, including the HX20V, HX90V, and the recently released HX99. HX represents HyperXoom.
Light-field camera
This kind of digital camera records data on the light field that emerges from a scene, including the direction and intensity of the light beams as they travel across space. In comparison to a traditional digital camera, it just captures the intensity of light.
Event video
Typically with microsecond precision, event cameras detect when the intensity of light changes by some threshold for each pixel independently, as opposed to measuring the light’s intensity across a predefined time frame (the exposure time).
Combination with additional devices
Numerous gadgets, such as laptop computers, PDAs, mobile phones, and smartphones, are equipped with an integrated digital camera. JPEG files are typically used to store the photos taken by built-in cameras.
J-Phone was the company that debuted mobile phones with digital cameras to the Japanese market in 2001. Camera phones surpassed film and digital stand-alone cameras in sales in 2003 and 2006, respectively. In just five years, five billion camera phones were sold; by 2007, more than half of the installed base of ย all mobile phones were camera phones. Sales of separate cameras peaked in 2008.[69]
