There are numerous manufacturers who dominate the production of digital cameras (often DSLRs). Aside from the physical technology that they manufacture, each brand embraces unique mission statements that set them apart. While the majority of camera manufacturers include modern features in their production, some specialize in specific aspects on the camera or within the system, as well as image quality.

Market Trends
Sales of smartphones (with built-in cameras) compared to digital cameras. From 2009 to 2013, smartphone sales soared, while camera sales remained stagnant.
Sales of smartphones compared to digital cameras 2009-2013
Traditional digital camera sales have fallen as more people use cellphones for casual shooting, which also allows for better photo processing and sharing via applications and web-based services. In contrast, “bridge cameras” have retained their ground by providing capabilities that most smartphone cameras lack, such as optical zoom and other advanced functions.[70][71] DSLRs have also lost popularity to mirrorless interchangeable-lens cameras (MILCs), which provide the same sensor size in a smaller camera. Some pricey ones use a full-frame sensor, similar to that found in professional DSLR cameras.
In response to the convenience and versatility of smartphone cameras, some manufacturers developed “smart” digital cameras that combine classic camera functionality with smartphone capabilities. Nikon and Samsung introduced the Coolpix S800c and Galaxy Camera, the first two digital cameras to use the Android operating system, in 2012. Because this software platform is utilized in many smartphones, they can interface with some of the same services (such as e-mail attachments, social networks, and photo sharing sites) as smartphones and run other Android-compatible applications.[70]
In an unusual move, some phone manufacturers have released cellphones with cameras designed to imitate traditional digital cameras. Nokia released the 808 PureView and Lumia 1020 in 2012 and 2013, respectively. use the Symbian and Windows Phone operating systems, and both include a 41-megapixel camera.[72] Similarly, Samsung released the Galaxy S4 magnification, which features a 16-megapixel camera and 10x optical magnification, integrating features from the Galaxy S4 Mini and the Galaxy Camera.[73] Panasonic Lumix DMC-CM1 is an Android KitKat 4.4 smartphone featuring a 20MP, 1″ sensor, the biggest sensor for a smartphone ever, a Leica fixed lens equivalent of 28 mm at F2.8, RAW image and 4K video capabilities, and a 21 mm thickness.[74] Furthermore, in 2018, Huawei P20 Pro is an Android Oreo 8.1 includes triple Leica lenses in the rear of the smartphone with 40MP 1/1.7″ RGB sensor as the first lens, 20MP 1/2.7″ monochrome sensor as the second.
lens and an 8MP 1/4″ RGB sensor with 3x optical zoom as the third lens.[75] Combining the first and second lenses produces a bokeh image with a higher dynamic range, whereas combining the mega pixel first lens and optical zoom produces a maximum 5x digital zoom without losing quality by lowering the image size to 8MP.[76]
Light-field cameras were first presented in 2013, with one consumer device and numerous professional options.
Following a significant drop in sales in 2012, consumer digital camera sales fell 36% in 2013. In 2011, small digital cameras sold ten million every month. In 2013, sales dropped to around 4 million per month. DSLR and MILC sales fell 10-15% in 2013 after nearly ten years of doubling digit growth.[77] Worldwide unit sales of digital cameras have been steadily falling, from 148 million in 2011 to 58 million in 2015, and are expected to fall further in the coming years.[78]
Film camera sales peaked at approximately 37 million units in 1997, while digital camera sales began in 1989. By 2008, the film camera market was perished, while digital camera sales peaked at 121 million units in 2010. Cell phones with inbuilt cameras were released in 2002, and by 2003, 80 million units had been sold annually. By 2011, cell phones with inbuilt cameras had sold hundreds of millions of units each year, triggering a drop in digital cameras. In 2015, digital
Camera sales totaled 35 million units, which is less than a third of digital camera sales at their highest and slightly less than film camera sales at their height.[Citation needed]
Connectivity: Transferring photos
Many digital cameras can link directly to a computer and send data:
Early cameras used a PC serial port. USB is presently the most used way (most cameras display as USB mass storage), however others have a FireWire connector. Some cameras connect via USB PTP rather than USB MSC, while others support both.
Other cameras, such as the Kodak EasyShare One, connect wirelessly using Bluetooth or IEEE 802.11 Wi-Fi. Wi-Fi integrated memory cards (SDHC and SDXC) can transmit stored photos, video, and other files to Computers or smartphones. Images can be automatically uploaded, backed up, or shared to photo sharing and cloud services via Wi-Fi on mobile operating systems like Android.
Cameras with built-in Wi-Fi or dedicated Wi-Fi adapters typically offer camera control, including shutter release, exposure management, and other functions (tethering), from computer or smartphone apps in addition to media data transfer.
Cameraphones and certain high-end standalone digital cameras use cellular networks to connect and share photographs. The most widespread cellular network standard is the MMS Multimedia Messaging Service, also known as “picture messaging.” The second approach for smartphones is to send an image as an email attachment. Many older cameraphones, however, do not support email.
A common alternative is to utilize a card reader, which may be able to read a variety of storage media and transport data to a computer at rapid speeds. Using a card reader also avoids exhausting the camera’s battery during the download procedure. An external card reader provides easy direct access to photographs on a variety of storage media. However, if only one storage card is in use, transferring it between the camera and the reader can be troublesome. Many computers have built-in card readers, at least for SD cards.
