Beginner’s Digital Photography Crash Course: History of Digital Cameras
Modern digital cameras come in three major types, compact cameras, DSLRs, and mirrorless cameras. Each has unique advantages and disadvantages, and all are capable of creating excellent photographs.

DSLRs are the camera type most people associate with professional photography. They have a variety of lenses that you can change out to create the photo effect you want. They are larger, heavier, and have a system of internal mirrors that direct light from the lens to the eyepiece (viewfinder). Because the viewfinder is above the path of light from the lens, the mirrors have to direct the light from the lens up to your eye. If you want to take a picture, the mirrors move out of the way. Light then streams straight from the lens to the digital image sensor. This sensor then records an image using the settings the photographer preset.
DSLRs are digital versions of the older SLR film camera. The major difference is the DSLR has a digital sensor to record images instead of a cycling roll of film. They are actually relatively new to the camera world. The first commercial DSLR was produced by Kodak in 1991. At an MSRP of $20,000, it used a Nikon S3 SLR body mounted to a large digital unit in the back. It was bulky and expensive, and ultimately lost to the more familiar looking Nikon D1, released by Nikon in 1999. The D1 was the first commercially viable DSLR, and ultimately led to Kodak losing its place as king of the photography world.
Compact cameras have a long history and it’s hard to say exactly which model was introduced first. Much of their design is owed to film cameras with digital elements, such as the Konica C35-AF, developed in 1977. The first truly filmless compact camera would be the Sony Mavica, released in 1981. It used the then standard 2 inch floppy disk as a storage medium. It could hold up to 50 images, and to see the pictures, you had to connect it to a television or computer monitor. From there, designs and memory cards have been compacted, and sensor sensitivity greatly improved.
Today’s compact cameras use an image sensor to create a viewfinder view, autofocus system, and photo all at once. Most are much more compact and portable compared to DSLR cameras. However, the lens of a compact camera is fixed to the body and can’t be swapped out. This means the lens is a general purpose one. A subject in tight focus with a blurred background may not be possible with a compact camera. Or if it is, then getting a long zoom range may not be possible with the same lens. Compact camera lenses sacrifice precision for versatility.
Mirrorless cameras are the new kids on the block. They have strengths from both the compact camera and DSLR families. Like compact cameras, they use a multipurpose image sensor to perform a variety of functions. Also like compact cameras, the lack of internal mirrors makes them lighter and more portable. And like DSLRs, they use an interchangeable lens system for customizable photography.
The first mirrorless camera commercially marketed was the Epsom RD-1, released in 2004 for $3,000. After that, Leica released the M8 in 2008, and Panasonic, Fujifilm, Olympus, Pentax, and others have followed suit. Nikon and Canon have released a few models but currently remain committed to the DSLR market. Mirrorless cameras are becoming more and more popular every year. People are realizing that DSLRs finally have a worthy competitor in the mirrorless line of cameras.
