Digital Trends’ digital camera buying tips:

What are my options?

There are two basic types of digital cameras-point-and-shoot and D-SLRs (Digital Single Lens Reflex). Point and shoot digicams-or as we like to call them “aim and forget”-make up the vast majority of models sold (over 90 percent). The reason is simple: in a single gadget you have everything you need to take good photos. Just aim, zoom in on your subject, press the shutter and the camera does all the work. More sophisticated D-SLRs have interchangeable lenses that let you unleash your inner Annie Leibovitz-they offer higher quality, faster response time and more flexibility. They also are a lot heavier and cost much more. Your decision between the two is purely personal and totally dependent on your level of commitment to photography. No matter which way you go there are basics that hold true for all cameras. Learning them will help you make the right decision.

What Should I look for in an LCD Display?

Camera manufacturers market display size quite prominently because it’s easy to visualize, but other factors also come into play. Resolution (usually measured in the number of pixels, like 461K) will determine how clear the display looks, and brightness will help determine whether it gets washed out when shooting outdoors. An optical viewfinder makes a great backup when shooting with a less-than-ideal LCD.

LCD screens are measured diagonally and 2.5 inches is a common size. We prefer even larger ones, up to 3 inches. If your eyesight is a bit challenged, definitely look for a larger LCD. Screens are measured in pixels, just like image size. Again, the more pixels, the better the image you’ll see on screen.

What about shooting video?

Within the past few years, video has gone from a novel sideshow that yielded almost unusably bad results, to a legitimate secondary purpose for many point-and-shoot cameras. Although you probablt won’t want to replace your dedicated camcorder with a camera that also shoots video, many will do the job just fine for short, impromptu clips.

First off, pay attention to the resolution a camera can capture – VGA (640 x 480) is now common on point-and-shoot cams, while 720p is getting more frequent and 1080p sometimes crops up on DSLRs. Video in the AVCHD format – the same type real digital camcorders shoot – is preferable to other formats. Pay attention to the encoding bitrate, measured in megabits per second (mbps). The higher the rate, the more detailed the videos will look, although they will take up more space on your storage card as well.

What are some basics I should look for?

Your new digital camera should have these key features:

  • At least a 6MP imaging device for a D-SLR
  • At least a 7MP imager for a point-and-shoot
  • Optical zoom of 3x, not just a digital zoom
  • The highest quality optics
  • A large LCD screen; the more pixels, the better the quality
  • The widest range for aperture (f/stops), shutter speed and ISO
  • An AF Illuminator or AF Assist mode for best flash shots in dim light
  • A variety of Scene Modes for more convenient shooting in a variety of situations
  • Make sure you do your own ergonomic hands-on test

How many megapixels do I need?

In 2000, the answer to this question was “more is always better.” In 2010, the answer is more likely “if you have to ask, you have enough.” Even the cheapest cameras these days typically pack eight or more megapixels onto a sensor, which produces superb 4 x 6 prints, all the way up to 8 x 10, and sometimes more. The physical size and quality of the image sensor along with the corresponding optics play a much bigger role in image quality than megapixels alone, so don’t be fooled into thinking more megapixels will produce better photographs. Unless you’re planning to blow up shots to poster or billboard size, any modern camera has enough resolution.
When you’re researching different cameras, manufacturers will state the maximum file (or picture) size you can take. In the case of a 6 megapixel (MP) camera, it’s 2816 horizontal pixels x 2112 vertical pixels, with 7MP it’s 3072 x 2304 and so on. Simply multiply the numbers and you get the effective resolution of the imaging device. We suggest you avoid anything less than 6 or 7MP at this point unless you’re looking for an inexpensive camera for the kids.
Pros have access to 21-megapixel imagers in very expensive D-SLRs. You don’t have to go this route or spend that much money for great everyday photos. However, 6MP should be your minimum and if you plan on making very large prints, such as 13x19s, or you feel you’re going to experiment cropping photos with imaging software, consider 8- or more megapixels. There are no hard and fast rules since so much depends on your final end use
