Are you searching for a quality digital camera? There are 4 characteristics that determine the best zoom camera as explained in this article.
- Zoom range
Zoom camera consists of variable focal length which dictates the lens magnification power. Shorter focal lengths have wide angles and are most suitable for taking big pictures. On the other hand, longer focal lengths are referred to as telephotos and they facilitate shooting of distant objects as tight images. The best zoom cameras integrate these features to form adjustable lenses. For example, camera rates 10X zoom has the longest focal length triple the shortest focal length. Supposing you use a camera with 35mm as the shortest focal length and a 10X zoom, the range would be 35mm-350m. The vast majority of digital cameras have a zoom power of 3X and focal length range of 35mm – 105mm. in this case the 35mm focal length is a wide angle while 105mm is for the telephoto. Some cameras consist of zoom ranges which are extreme like 10x but their lowest focal lengths are about 35mm hence the highest focal length is very long (350mm). Such a longer focal length means that tight photos are achievable since they allow the camera user to get as close as possible to the object even from the field’s sidelines.
The ads for the best zoom cameras often come with both digital and optical zoom specifications. The digital zoom is not important and all that counts is the optical zoom. The former only works to crop the picture, something that can be done using photo-editing software. Many a times, longer focal lengths, say of 300mm, are problematic in that it becomes difficult to stabilize the camera. This is where tripod stands and stabilizer lenses come in handy to prevent blurred images as a result of camera shakes. Camera stability means a lot to a photographer as it is one way in which sharp footages are attained when extreme focal lengths are used.
- Lens aperture
This is equivalent to the maximum amount of light that can be gathered by a lens. Bigger apertures allow in more light. This is an a quality you must not overlook if you are seeking the best zoom cameras for taking indoor shots without the use of a flash or when you want to take photos from afar. The aperture is normally denoted as f/no. e.g. f/4.5. If the camera aperture is specified as f/5, it means that the lens opens only a fifth of the focal length. Therefore, the smaller the specification number, the larger the aperture. That means that f/3 lens is better than f/4. Bigger apertures can take images in dim places and they would seem even more natural than pictures taken in flash. They are especially perfect when you want to take a lot of photos in a limited time period without letting others notice. If you are shopping for the best zoom camera, look no less than a f/2.8 aperture unless your budget restricts you.
Most of the digital cameras have a CCD’s sensors for taking film. Resolution means the amount of pixels of a shot image. Pixels on the other had are basically small computerized dots. A more detailed image consists of more pixels. An 8 Megapixel camera can produce images which would accommodate bigger prints than if a 3 Megapixel camera is used.
- Lens quality
Just because a 2 lenses have similar apertures and focal lengths doesn’t mean their quality is the same. Poor lenses have chromatic aberrations and they don’t give sharp images. Such distortions normally appear as colored fringes on very high contract parts. The lens quality, unfortunately is not specified anywhere on the camera box. The only ways to determine if a camera lens is of high quality is by checking customer reviews or ask for references of acclaimed camera companies.
- Factory-built software
Some of the best zoom cameras come with inbuilt software. Taking digital shots is a computerized activity. Before taking an image, a camera takes a pre-photo to check color balance and brightness of the field. Then the actual photo is shot based on the information gathered beforehand. This is a very crucial aspect of a lens. In digital photography, you want to be sure that the color and illumination of the picture goes well. The good thing about zoom cameras is that they offer good color rendition hence avoiding too much custom work.
- Media type
In most cases, zoom cameras use secure digital or compact flashes. The difference between the two is not a big issue. The important thing is to keep in mind the recommended SD card and its class. This is very important when taking footages in rapid succession.
