Before deciding to choose which Lumix FZ38 digital camera to buy, it is important to look at a series of factors. The most important factor to consider is the use of the camera. Whether it is intended for professional or domestic normal use. When this is determined then it will be possible to decide on the price. Understanding the technical terms that define the features of the camera is an important step in making the right purchasing decision. Pixels are the tiny dots of color that make up a digital image, and the image size and resolution, or quality, are calibrated in megapixels. The higher the megapixel figure, the higher the quality and the larger the picture a camera can take. Another interesting feature to be considered is the camera zoom. It defines the method by which the camera focuses on and enlarges distant objects to make them appear closer to the viewer. Digital cameras offer a choice of either optical or digital zoom, and the buyer has to be savvy in their choice. Optical zoom operates on the principle of magnification using a combination of lenses, while digital zoom utilizes software based algorithms to enlarge the image taken. Generally, it is better to have a larger optical zoom than digital figure to ensure sharper images when this feature is utilized. In some cameras, the buyer is offered both digital and optical zoom options in the same camera. This combination provides sharper images and higher zoom sensitivity. The zoom number is a multiple of the number of times the camera can reliably enlarge the image taken, while the focal length is the difference between the two types. The ability to zoom in and out is down to a camera having a variable or fixed focal point, with the former allowing for zoom operation. Macro lenses allow cameras with this feature to reproduce exceptionally high quality images as they provide the capability for extremely detailed close-ups of the subject, producing a very professional looking photo. This is a much sought-after feature especially with nature photographers. Another feature of digital cameras is the ISO. The ISO is a measurement of the sensitivity of the camera to light. A higher ISO figure is an indication of a higher sensitivity to light, and results in the reproduction of sharper, more vibrant images. There is also the shutter speed and aperture. A high shutter speed enables the camera to take clear action shots, while a slower shutter speed enables capturing of fast moving objects. The aperture, on the other hand, controls areas of focus on an image. The Lumix FZ38 camera is well built and long-lasting camera available at reasonable prices.
