There are many factors to consider when buying a Digital Camera. Let’s look at the Image sensor, Processor chip, and Field of view. Knowing these features will help you make the right decision. Whether or not these factors matter will depend on your personal preferences and requirements. You can start your search by browsing through our comparison chart below.

Image Sensor
The image sensor is the light-sensitive component of a digital camera, and it is responsible for recording a digital image every time you press the shutter button. DSLRs use either APS-C or full-frame image sensors, while mirrorless cameras use the Micro Four Thirds sensor. Both types are effective for capturing high-quality pictures, but each has its own pros and cons. Learn more about the features of these sensors and which one works best for your needs.
The first digital camera was developed by Kodak in 1973, though it never made it to the mass market. Despite the early failures, the development of increasingly complex image sensors continued apace. Silicon-based image sensors are widely used in digital cameras. As a general rule, the bigger the sensor, the better the picture. In general, a digital camera’s image sensor consists of a grid of millions of micro-elements, or pixels. Each pixel contains a photodetector, and a larger sensor yields better picture quality and you can check that out on usglobalworld.
Memory Card
While it’s easy to decide which Memory Card to get for your camera based on capacity, price, and speed, there are other things you should consider as well. While high-capacity cards are more expensive, you don’t want to spend more than you have to. Also, a low-cost Memory Card is likely to be slower, and prone to errors. You can find cheaper models, but these may not be worth the money in the long run.
Besides increasing the speed of writing, a memory card should be formatted to ensure that it will hold as many images as possible. Most digital cameras will allow you to do this through the menu of the camera. This is an easy way to free up a lot of storage and fix minor problems. You must remember to save your images first before formatting a card, as you may lose them. Alternatively, you can purchase a memory card reader. For example, a SanDisk ImageMate Multi-Card USB 2.0 reader can speed up the read and write speeds.
Processor Chip
The Processor chip in a digital camera is the main component of a camera. The light reflected by the scene is first sent through a lens and several filters, including the RGB color filters. The signal is then converted to digital before being sent to an ASIC. This specialized chip processes images, data, and file information, and may then be sent to an LCD display or memory. The microprocessor in a camera is responsible for controlling a variety of camera functions, including focus, zoom, flash, and user controls.
Cameras are often equipped with a processor chip, which handles many functions, such as RAW/Jpeg handling, file storage, and other functions. Unlike desktop computers, a camera’s processor can’t run an operating system like Windows or OSX, so it’s important to select a processor chip that can cope with higher levels of data in less time. Fortunately, there are now processor chips for a wide variety of cameras, including many DSLRs and compact cameras.
Field of View
The Field of View (FOV) of a digital camera is the angle of view that can be obtained from a photo. The FoV calculation is based on the size of the sensor, as well as the amount of magnification. The sensor’s size can be measured in several ways, such as by the diagonal across it. Cameras with CCD and EMCCD sensors typically have smaller sensors than those used by SLRs, and the maximum magnification available is around 0.8x.
A wide FOV allows for a more expansive field of view. For example, a 20mm lens on a full-frame camera will have a 94-degree FOV. Conversely, a 13mm lens on a 1.6x crop sensor will have a field of view of just six degrees. Ultimately, the FOV depends on the focal length and sensor size. The higher the focal length, the narrower the FOV will be.
Manual Controls
Before you start shooting, you should familiarize yourself with the manual controls of your camera. These controls are typically located on the camera’s back or front, but different manufacturers have different conventions. Nikon, for example, uses the back dial for aperture and Canon uses the front dial for shutter speed. Point-and-shoot cameras have only one dial, and some even have navigation buttons for each of these settings. Regardless of the type of camera you’ve bought, reading the manual is the best way to learn the proper exposure settings for your subject.
A camera’s automatic mode can make shooting images too difficult. You may end up getting blurry or shallow depth of field. A manual mode gives you total control over the photo, but be prepared to spend more time practicing it to become instinctive. You might even want to consider switching to program mode if your camera has no manual mode, which allows you to make adjustments to the camera’s settings without a manual setting.
Image Stabilisation
Image stabilization on digital cameras is an excellent way to take pictures in challenging situations without blur. However, when using a tripod, the benefits of image stabilization can be negated. This is because the IS system detects its own vibrations and starts moving even when the camera is perfectly still. It is this motion that introduces blurriness to the image and is one of the main reasons for avoiding the use of image stabilization.
One of the most effective ways to combat camera shake is by using a system to compensate for rotation, pan, and tilt. This technology is found in high-end binoculars and still cameras. It is particularly problematic when using long focal length lenses and slow shutter speeds, as this causes visible frame-to-frame jitter. In astronomy, the problem is exacerbated by the presence of light and atmosphere variations, which can alter the apparent positions of objects over time.
