Faster, smarter, better — that's the allure of owning a DSLR (digital single lens reflex) camera. Professional photographers choose DSLRs for their ability to capture brilliant, breathtaking images. But DSLR cameras aren't just for the pros. They're also the choice of many intermediate users and even beginners, as well.

DSLR Cameras: 3 Things To Know

  • DSLR cameras are more powerful than point-and-shoot cameras or camera phones. DSLRs have bigger image sensors and give you more control over the shot, for better image quality. And, their ability to change lenses gives you many more shooting options. Plus, today's DSLRs provide a host of easy-to-use automatic features, so everyone can get great results right out of the box.

DSLR Camera Kit or Camera Only

  • DSLR camera kits include the DSLR camera and a lens (body and lens). The kit typically comes with a versatile lens such as one with an 18–55mm zoom factor. With any of the big brand names, you can be confident you'll be getting a good, general purpose lens that will perform respectably over a wide variety of shooting situations. Plus, one of the big advantages of a DSLR camera is your ability to purchase interchangeable lenses to capture more specialized shots such as panoramic landscapes, long zooms and extreme close-ups.

    You also have the option to purchase your DSLR camera without a lens (body only). Choosing a body-only camera may make sense if you already own a DSLR or SLR camera along with a collection of lenses, or if you simply prefer to select your own specialty lenses. Be sure to verify your existing lenses are compatible with the new camera you're considering.

APS-C vs. Full Frame Sensor

When purchasing a DSLR, you'll have the choice of selecting a camera with either an
APS-C image sensor (also known as a crop sensor), or a full frame image sensor.

But before comparing DSLR sensors, it's helpful to understand what an image sensor is, and how DSLR sensors compare to those of other cameras. The image sensor in digital cameras is a light-sensitive component that digitally records the image once the shutter
is pressed.

The image sensor in DSLR cameras is much larger than those found in camera phones
or even in point-and-shoot cameras. This is important because when it comes to image sensors, bigger is definitely better. The size of the sensor ultimately determines how much light it uses to create an image. And more light provides better digital information to create a more highly-detailed image. Check out the images on the right to compare APS-C and full frame DSLR sensor sizes to those of other camera types. It's easy to see that DSLR camera sensors are significantly bigger.

APS-C sensors are certainly capable of rendering exceptional images, which will be far superior to the images you can capture with virtually any point-and-shoot camera or camera phone. Or you can step up even further to a DSLR camera with a full frame sensor. The full frame sensor will capture an even bigger image than an APS-C sensor. Besides bigger images, which are great for landscapes and other panoramic shots, another advantage of the full frame DSLR camera's bigger sensor is that it captures more light, providing sharper, cleaner images, especially in very low-light situations. However, for zooming in on distant objects, an APS-C sensor will fill the frame with your subject more completely than a full frame sensor.

The bottom line on the choice between an APS-C or full frame sensor is that while professionals may prefer a full frame DSLR, that may be overkill for beginning-to-intermediate photographers, because you can certainly get outstanding results
with an APS-C sensor.


The resolution of digital cameras is measured in megapixels. A megapixel is equal to one million pixels. One pixel is essentially the smallest unit of a digital photo. When it comes to megapixels, you're probably familiar with the conventional school of thought that states: the more megapixels the better the resolution, and the better the digital image. But actually that's a bit of a stretch because all megapixels are not created equal.

Camera phones, for example, often sport what sounds like an impressive number of megapixels. After all, it's pretty amazing to pack 30 or 40 million pixels onto a relatively tiny sensor. But to do so, there is a trade-off. To pack those millions of pixels onto such a small sensor, camera phones, and even point-and-shoot cameras, simply make use of much smaller pixels than DSLR cameras. But small pixels simply don't behave as well as much larger ones, such as those found in DSLR camera sensors. The bigger pixels of DSLR cameras absorb light better, produce better color and are not nearly as prone to "noise" and color distortions.

Of course, if all else were equal, more megapixels would be an upgrade. But typically, all things are not equal, especially when comparing megapixels across different camera types. A 12-megapixel DLSR camera, for example, will invariably outperform even a 24-megapixel point-and-shoot camera, or a 40-megapixel camera phone.

Image Processors

The components found in DSLR cameras are typically more advanced than those
found in other cameras. The image processor, which is like the brain of a digital camera,
is no exception.

It's difficult to compare DSLR camera image processors across brands because manufacturers typically do not offer easily comparable specs. And another consideration
is the proprietary software that each manufacturer has painstakingly designed to function with their cameras' image processors. The results of image processors and software working in tandem is essentially what produces many of the artistic and effects capabilities built into DSLR cameras, and controlled by various settings.

So, you can certainly compare image processors within a given brand, using relevant information such as how much faster their latest image processor is versus their previous model. But that doesn't help for comparing image processors across different brands. One way to evaluate camera processors between brands is by their ability to meet your needs. Since the speed and capabilities of any digital camera are functions of its processing power, you can look at their ability to handle processor-intensive tasks. For example, how many frames (photos) per second it can handle in burst mode? Does it have on-the-fly autofocusing capabilities in high-definition movie mode?

Lastly, as technology evolves, camera image processors are continually improving.
DSLR image processors are significantly faster and more powerful than their point-and-shoot camera counterparts. Beyond that, some DSLR cameras have begun utilizing multiple processors, giving them the obvious advantage of further enhancing speed
and performance.


  • Aperture range, shutter speed and ISO sensitivity are the basic elements of exposure. Having full control over these settings as well as many more, sets DSLR cameras apart from other camera types. But, if you're not quite ready to take over the helm of making manual adjustments don't despair, because those easy-to-use automatic settings on DSLR cameras will take the guesswork out of getting great shots.

Flowers shot at two apertures


Every lens has an aperture range. Aperture adjustments are measured in units called f-stops. The higher the f-stop number, the smaller the aperture and the less light that passes through the lens. Higher f-stops increase the distance in front of and behind the focus point, making more of the image look "sharp."

Alternatively, a lower f-stop means a larger aperture and more light passing through the lens. Lower f-stops decrease the distance in front of and behind the focus point, making more of the image look "diffused" rendering a softer, more stylish effect.

If your f-stop is set at f/22, for example, the majority of your scene will be in focus. However, if your lens has the ability to go down to f/2.8, only a small portion of your scene will be in focus while the rest is blurred for that softer, stylized look.

Another advantage of DSLR cameras is the ability to utilize a very fast lens, such as f/2.8 or faster, allowing you further enhance the DSLR's ability to give you great shots, even in extremely low light.

  • Shutter Speed

    Think of your shutter speed as the gateway that controls the amount of light that streams into the camera. The longer the shutter is open, the more light that is allowed
    to enter the camera and the greater the image blur. With a DSLR, it's easy to adjust
    to the perfect shutter speed for any lighting situation. In low-light settings it makes sense to have a longer shutter speed to let in more light. It's just the opposite in
    bright situations.

    Why does it matter? When it comes to your kid's soccer game, it won't matter whether you capture the big goal if the picture ends up looking like a blurry mess. A faster shutter speed will freeze the action, making unwanted blur a thing of the past. On the other hand, you might want a degree of motion blur for style or artistic value. A slow shutter speed combined with subject movement during the shot, will create that motion blur. Alternatively, in a still shot, you might want to let in the brilliance and beauty of all available light. A slow shutter speed will give you that shot.

ISO Sensitivity

ISO sensitivity is a measure of how sensitive your sensor is to incoming light. An easy way to think about ISO settings is to understand that dimmer lighting conditions call for higher ISO, while brighter scenes require a lower ISO number. DSLR cameras are capable of shooting at much higher ISO numbers than most point-and-shoot cameras. This provides the flexibility to capture shots over a much broader range of lighting conditions, often eliminating the need for a flash in low-light conditions.

A good rule of thumb is to always use the lowest ISO you can get away with. That way you have proper exposure with as little graininess as possible. But with a DSLR camera, even when shooting at high ISO numbers, you'll get much sharper pictures with far less noise than on a smaller sensor camera, such as a point-and-shoot. Plus, another great thing about a DSLR is that you can choose manual control of your ISO sensitivity. However, if you're a beginner, you may opt to simply set your ISO to Auto and let the built-in technology do the work for you.

Cool Features

  • The majority of features discussed next are not exclusive to DSLR cameras. You might find them on your point-and-shoot camera or even on your camera phone. The important distinction here is that these features work even better with DSLR cameras, because of their superior components, speed and performance.

Burst mode

Burst mode refers to taking a rapid succession of photos by holding the shutter button. Burst mode is measured in frames per second, which means the number of pictures taken in one second's time. Some DSLRs can take as many as 10 shots per second, or more. After you take a "burst" of multiple photos, you can review them all and choose the best one.

Burst mode requires significant processing speed and power to accomplish the task. That's why DSLR cameras, with their ample processing power, are ideally suited to shoot in this demanding, high-speed mode. To take advantage of the speed of your DSLR camera, you'll want to outfit it with a suitably fast memory card that can keep up with the camera. Check out our section on memory cards below to learn more.

So what can you capture in burst mode? Here are some guidelines to look for depending upon your needs:

  • General photography: 3 frames per second
  • Kids, pets, other moving subjects: 5 frames per second
  • Sports, wildlife, fast-moving subjects: 5 to 10 frames per second

  • Multipoint autofocus & scene-recognition modes

    Virtually every camera these days has autofocus, and most cameras let you select a type of scene, such as portrait, landscape, indoor, and modes, etc. So, what more could you need? Actually, quite a bit. The capabilities of DSLR camera multipoint autofocus and scene-recognition modes provide more precise automatic control over a good many more shot settings.

  • Multiple-point autofocus feature locks onto moving subjects, tracking and keeping them in constant focus, which is great for capturing action shots and is especially useful in video mode.
  • DSLR cameras may offer automatic scene recognition, selecting the correct mode and the right exposure, so you don't have to.
  • Face recognition feature adjusts balance and focus points to show people's faces in their best light.
  • Many DSLR cameras can make a variety of autofocus and exposure adjustments on the fly — automatically adjusting numerous settings, all in the time it takes to press the shutter button.

The list goes on, depending upon the camera you choose. But regardless of your selection, you'll find these automatic DSLR camera modes go far beyond autofocusing the camera, making it easy to get great results from the outset.

  • High Dynamic Range (HDR)

    If you still think that DSLR cameras are just for the pros, try this function on for size. Cameras with an HDR function can take a number of pictures of each scene you select — all at different exposures. Then, the camera will determine the best parts of each photo to keep, as well as which parts to toss. Here's where the magic happens. The camera then combines the best parts of each photo into one great shot.

    Now, suppose for a moment that when the lighting was just so, you had framed up a picturesque sunset shot. And you were pretty sure your exposure settings were just right to capture that image perfectly. So you took the photo. When
    you reviewed the shot, you discovered you actually needed a little more light to create just the right effect. By that time, it's too late. But in HDR mode, you'd have captured multiple shots in rapid succession, each at a slightly different exposure. Then voilá, your camera would automatically combine the best elements of each shot to create a photo that's superior to any of the
    individual shots.

Video monitor
  • Video mode

    Another way DSLR cameras set themselves apart is in video mode. Because of their light-gathering sensors and lenses, DSLR cameras are able to capture Full HD videos that feature highly detailed images, and bright, brilliant colors. Plus, more and more DSLR cameras include special autofocus technology for video, so you can keep moving subjects in focus to capture the perfect video.

  • Wi-Fi-enabled cameras

    Let's skip ahead — you're at your kid's game with your new camera. Your kid breaks away with the ball, shoots, and scores. Now what? Share with grandma and grandpa, of course. But why wait until you get home to upload everything? Wi-Fi capability, available on some cameras, allows you to easily upload your photos to a smartphone or tablet for instant, wireless sharing. Some cameras even feature GPS technology that allows you to tag where your photos
    were taken.

Your Purchase Decision


DSLR cameras span a wide range of prices, from entry-level models to full-on professional cameras. Of course, as you move up in price range, you'll be moving
up in quality and features. But before determining how much to spend, you may
want to consider exactly what you'll be using the camera for and which features
you'll actually need.

When shopping DSLR cameras, you can shop by price range to suit your budget.

DSLR body & lens or body only

You may want to choose from DSLR cameras complete with a good,
general purpose lens.

Alternatively, if you already own a collection of lenses, or prefer to select a
particular lens or lenses on your own, you may prefer to browse DSLR camera
bodies without lenses.

    While, megapixels are often overrated, (See Megapixels section above), they could play a role in your purchase decision. With even a 12-megapixel DSLR camera, you'll be able to make gorgeous enlargements of 8" x 10" or 11" x 14". However, if you intend to do significant cropping, enlarging from there, you'll certainly benefit from more megapixels, which will help to maintain resolution.

Features that meet your needs

  • Are you shooting sports or wildlife photographs? A camera with a fast burst mode and advanced autofocus system could ensure you get that critical shot.
  • Are you shooting landscapes, sunsets, or architectural photos? A high-megapixel camera or full frame DSLR will not only give you the resolution and light-gathering capacity to ensure you get breathtaking shots, but also give you the ability to maintain resolution while cropping and enlarging.
  • Do you like to shoot during the beautiful natural light around dawn or dusk, or to take dramatic nighttime shots? A camera with a high maximum ISO capability will prove most useful in low-light situations.
  • Do you like to frame up your shots using the LCD monitor? You may be very interested in models with an articulating screen, which gives you the ability to confirm you've properly framed the photo while capturing shots from all kinds of interesting angles. Plus, many monitors have a touch screen for adjusting and confirming settings or easy navigation for reviewing or editing photos.

  • Memory cards

    Type — The memory card is where all the images and videos you shoot are recorded and stored. Important note: Cameras typically do not come with a memory card. So, you'll definitely want to order a memory card, or several, with your camera. Different memory card types exist, such as secure digital high capacity, or SDHC, or compact flash. Some cameras accept multiple types of memory cards. The important thing is to purchase the correct memory card for your camera. It's a good idea to carry at least one backup memory card, in case you fill the one you're using.

    Capacity — A memory card's capacity is measured in gigabytes, or GB. Memory cards vary in size from 2GB all the way up to 128GB or more. People invariably ask the question, how many photos and how many minutes of video with a given capacity memory card hold? The short answer is, it depends on a variety of factors such as file size, resolution, among others. That said, you may want to check out the memory card capacity chart below, provided courtesy of SanDisk Corporation. It will give you a better idea how many photos or how much recording time you can expect various memory card sizes to hold in given situations.

    Speed — For most DSLR use, and especially during burst mode or movie mode, a high-speed memory card is critical. If you're not using a high-speed memory card, your camera may take pictures faster than the card can handle them, and you might lose the perfect shot. Not sure what makes a memory card high speed? Focus on the card's data transfer rate. You'll want to look for transfer rates of at least 20MB/sec. For action shots with high frame-per-second bursts and HD video recording, a very fast memory card of 80MB/sec.
    or more is recommended.

    Camera bags

    A dedicated DSLR camera bag provides space and compartments for your camera and accessories, and padding to protect them.

    Additional lenses and filters

    A versatile, general-purpose lens that comes with many DLSR cameras will cover a broad array of shooting situations. But when the time comes that you want to take truly stunning wide-angle panoramic shots, zoom in from great distances, or capture stunning close-ups with your foreground subject sharply in focus, set upon a stylishly blurred background, the ability to change lenses is a must. It's this ability to change lenses that gives DSLR cameras a leg up on other camera types for truly professional-looking results.

    Attaching a filter to your lens will protect it from dust and scratches. Plus there are also a variety of specialty filters that offer photo-enhancing features.

    Even though you may think you're rock-steady with a camera, longer exposure times
    may necessitate using a tripod. A tripod is practically essential for capturing truly flawless portrait or landscape shots, especially when shooting at night. Essentially, all tripods will
    fit all DSLR cameras, so you simply need to decide the size and features you prefer and which tripods suit your budget.

    External flash

    Most DSLR cameras include a built-in flash — a handy means to provide extra light any time you need it. But, because a built-in flash has to be compact to fit the camera, it cannot offer the power of an external flash. An external flash is much more powerful than the built-in flash, and gives you greater control over the lighting. Other advantages include better illumination, a cleaner, softer look, more natural lighting, red-eye reduction, and flexibility in the positioning of lighting. Lastly, an external flash runs from its own battery source, so unlike a built-in flash, it won't drain your camera battery.
