Kodak Digital SLR Cameras

Choosing a Kodak Digital SLR Camera

People have been using digital cameras to record their memories ever since Steve Sasson invented the first one in December 1975 while working for Eastman Kodak. Called single-lens reflex (SLR) cameras, these cameras come in many different varieties, but they all use a mirror and prism system. A mirror flips up out of the light path when the shutter button is pressed on an SLR camera, allowing the image to be captured.

What types of digital SLR cameras are there?

Generally, digital SLR cameras fall into five different categories including:

• Cropped sensor: These cameras capture less of the image than is viewable through the viewfinder.
• Full-frame sensor: These cameras capture exactly what the user sees through the viewfinder or on the screen.
• 4/3: The sensor in these cameras is smaller than the sensor used in other SLR cameras.
• Micro 4/3: These cameras use an electronic viewfinder to broadcast the image onto the viewfinder.
• Video/still: In addition to capturing still images, these cameras can also capture video.

What is the difference between optical and digital zoom?

Optical zoom enlarges the entire image to fill the whole sensor area. It is the measurement of the actual measurement of the distance between the center of the lens and the image sensor. As this zoom increases, an increasingly smaller area of the image strikes the sensor. Digital zoom only takes the center of the image and enlarges it to fill the sensor while eliminating the outside of the image. Digital zoom automatically adds pixels to an image.

Do digital SLR cameras use interchangeable lenses?

Yes, digital SLR cameras like those made by Kodak use interchangeable lenses. This means that you can choose the perfect lens for your shoot, whether youre shooting a tiny object that is close up or an object several feet away. There may be many different types of lenses available including;

• Prime: These lenses have a set focal length.
• Telephoto zoom: These lenses allow you to get closer to the image without physically moving.
• Macro: These lenses are designed to magnify small objects allowing them to fill the complete sensor.
• Wide-angle: These lenses allow the photographer to capture a wider field of vision.

What is the difference between pentaprism and pentamirror systems?

Pentaprisms and pentamirrors both reflect the light coming through the lens so that the image appears correctly on the cameras viewfinder. Pentamirrors are made of glass and may have hollow parts, so the image often appears darker on the viewfinder. Pentaprisms are made of reflective plastic. Pentaprisms may weigh a lot more than the alternative adding to the cameras overall weight.
