Panasonic Lumix DMC-G3 (Body Only) Reviews: Digital SLR Camera

There are 2 main types of camera: The SLR and the Compact.

SLR stands for Single Lens Reflex. SLR cameras use a prism to reflect the exact image as seen through the lens and so offers a more accurate viewfinder. SLR cameras have detachable lenses offering greater flexibility if you wish to take a variety of different photographs.

Compact cameras have a built in lens and an ‘above lens’ viewfinder which is less accurate but they are often cheaper, more sleekly designed and easier to carry anywhere with you to capture that moment perfectly without having to fiddle with complex settings or a bag full of lenses.

Screen size is measured diagonally from corner to corner.

If a photo is taken at a slow shutter speed, or at a long focal length, the effects of ‘hand shake’ will be amplified. Some cameras come with built-in image stabilisation which is designed to act against this to produce sharper images.
It’s great for low light shots without a tripod, like at a gig.

This is the type of storage that your digital camera or camcorder uses to save images to.

The main types of card media format:

Compact Flash
Micro SD
MMC (Multi Media Card)
SD Card (Secure Digital)
SDHC (Secure Disk High Capacity)

Almost all modern cameras have autofocus. Manual focus allows you to override the autofocus and set the distance yourself. This is especially useful if your camera is struggling to focus in a low-light or confusing scene.

Whether or not your camera has an in-built flash.
Flashes are essential for fully capturing a low light image.

This is the fastest speed at which the camera can take a photo. Faster shutter speeds really freeze the action and are great for sports photography.
