Buying a Digital Camera? Read This Buying Guide!

Apr 11, 2008
Many digital cameras with upgraded technology are being introduced every day. This makes it more difficult to select a camera, as you are left with a wide range of models to choose from. However, most buyers have specific features and needs in mind. Rather than going for the latest model, buy digital cameras that best suit your requirements.

What should I look for when buying a digital camera?

The cheap camera lenses, resolution, display size, performance and battery life should all play a significant role in your buying decision. Here are some features to keep in mind while picking the right camera for yourself.


Resolution is typically defined as the number of pixels that make up a picture. A digital cameras resolution is closely related to image quality. You need a high resolution camera to shoot and print highly detailed photographs. If you want to enlarge and crop any of your photos without loss of clarity, go for cameras that offer a higher resolution. If you do not intend on printing your photographs and would rather email them to friends, a lower resolution camera would be a better choice. They are more affordable and still produce fairly good images.

Memory and Connectivity:

Generally, digital cameras have a removable storage option, such as a memory card slot. Digital cameras support a wide range of formats like flash memory, memory sticks, SecureDigital cards, SmartMedia cards and xD Picture cards. Many TVs, laptops, digital photo frames and some gaming consoles have memory card readers, so you can easily view photos that are stored on memory cards. If you want to save money, store photos on the cameras internal memory rather than on a memory card and transfer them to a PC or Mac using a USB cable. Digital memory is a huge time and money saver!


Rechargeable batteries are highly recommended because they can be charged and reused again. Recent cameras are compatible with NiCad, NiMH and lithium-ion batteries. Though NiCad and NiMH are inexpensive, lithium-ion is worth the extra money. They are long-lasting batteries with low self-discharge rates. You should opt for cameras that are compatible with lithium-ion batteries. A few cameras come with an AC power adapter that can be used to charge the digital camera battery as well.


Digital cameras come with two types of zoom lenses, optical and digital. Both of these zoom lenses allow you to take close-ups of a distant subject, although they accomplish this task through different means. The optical zoom magnifies the image before the shot is taken, whereas the digital zoom artificially magnifies the image by enlarging the pixel area but this leads to a loss of resolution. You should pay more attention to the optical zoom rather than the digital zoom when comparing models.


Most cameras available today have preset modes for shooting images under different conditions. Factors such as exposure, aperture, focussing, light metering, white balance and sensitivity can all be adjusted. Many digital cameras also include video capture modes, enabling you to take short videos at different frame rate speeds.

ViewFinders and LCD Displays:

The optical viewfinder is the window you look through when taking a picutre. Although there are digital cameras with viewfinders, several of the latest models have only an LCD display. The LCD screen lets you view an image as you take it and also plays back pictures and videos saved on your camera. Anti-glare screens are best for buyers who plan on shooting a lot of photos outdoors. If you need a durable camera for rough use, opt for a scratch resistant screen.


Digital cameras also come with innovative technologies that make photography fun and easy. Do u want to avoid overexposed or darkened faces, recognise multiple faces or optimize the color and tonal qualities of your photos? Not a problem. Todays cameras are well equipped with automatic red-eye and camera shake detection and correction as well as multiple face recognition. Not no meantion tons of

What are the different types of cameras and camera accessories online or available through conventional stores?

Point-and-Shoot Models:

Point-and-shoot cameras are a dime a dozen. These entry level models provide low resolution with little magnification. If you do not want to spend time on focusing and figuring out the settings and controls, a point-and-shoot camera is just the ticket. You will find plenty of these models that are low in cost and easy to use.

Intermediate Models:

These models are especially designed for beginners. Equipped with a range of automatic settings, these consumer-level digital cameras produce flawless pictures. They usually have a resolution of 3.2 to 5 megapixels and a 3:1 to 4:1 zoom lens.

Advanced Consumer Models:

If you have taken a class or photography is one of your hobbies, then you will probably want some additional features. Choose from the many advanced consumer models with higher resolutions, quality lenses and morer zoom. These models let you add features based on your needs and give you the freedom to personalize the settings.

Prosumer Models:

When you buy digital cameras, if consumer models are too basic for you and professional models are too complex, you will love a prosumer model. These sophisticated cameras have the best of both worlds. They have a vast number of options to work with, like switching between automatic and manual focus, selecting the shutter speed and adjusting the aperture settings. You will also have the opportunity to express your creative side by manipulating images. You can adjust the brightness and contrast levels for truly unique snaps. You can expect a minimum of 5 to 6 megapixels in this category. These digital cameras can take 2 to 3 pictures per second, but tend to be more fragile than other models.

Professional Models:

You will need a top of the line model that sports the latest features to meet your high demands, if you are a professional photographer. Professional models are capable of producing high resolution images with magnificent colors and clarity. They have interchangeable lenses and a resolution of up to 14 megapixels. These models are the fastest on the market, allowing you to take 5 pictures per second. Professional digital cameras have a whopping storage option of at least a 1 GB mini hard disk drive, on an average.
