HOW TO FIND THE RIGHT DSLR CAMERA
November 8, 2017
BY ITTEHAD ASIF
1. Introduction
For professional photographers and advanced hobbyists, digital single
lens reflex (DSLR) cameras are the way to go. They offer faster
performance, more control over settings, and better image quality than
top-of-the-line point-and-shoot cameras. Most importantly, they give you
the ability to switch lenses.
Thanks to recent innovations, DSLRs and compact interchangeable lens
cameras (also known as compact system cameras) are growing in
popularity with the hobbyist and enthusiast crowd.
Many DSLRs now feature preset shooting modes, friendly interfaces,
helpful guides, and more compact designs. Mirrorless interchangeable
lens cameras are proliferating and growing more popular than ever with
their lightweight, sleek, stylish looks and advanced functionality.
While you can find consumer DSLR and interchangeable lens cameras
for well under $1,000, they are a considerable investment. How do you
choose the right one? We’ve got some tips on shopping for a DSLR or
interchangeable lens camera if you’re in the market for one this holiday

Understand the basics
1:The megapixel myth: A high megapixel count doesn’t mean better
image quality. However, it does give you more flexibility when cropping
or making enlargements. These days most cameras offer a resolution
of at least 10 megapixels, which is overkill for most shooters. A 5-
megapixel image is enough to make a sharp 8-by-10 print. An 8-
megapixel image is enough to make a sharp 11-by-14 print. A 10-
megapixel file can produce acceptable prints of up to 13-by-19 inches,
though they may lose some detail. Images from a 13-megapixel camera
look good at 13-by-19 inches and can be pushed to 16-by-24 inches.
Many DSLR cameras today exceed 13 megapixels—all the better to
creatively zoom in and crop your images. Keep in mind that higher
megapixel counts also produce larger files, which in turn take up more
space on your camera’s memory card and computer’s hard drive.
Pay attention to sensor size: Cameras with larger sensors and better
lenses normally take better shots, regardless of megapixel count.
Bigger sensors normally create better images, as do higher-quality
lenses; this is why DSLRs take such stunning photos. If you can’t get
any hands-on time with a camera before deciding whether to buy it,
make sure to check the specs to see its sensor size, and compare it
with any other camera you are considering purchasing. Typical terms
you'll run into when examining camera sensor types are CCD (charged
coupled device) and CMOS (complementary metal-oxide
semiconductor). When considering sensor size, you'll confront terms
like Four-thirds and Micro four-thirds, APS-C, full-frame, and more.
Large sensors are not confined to interchangeable lens cameras
anymore, either. Sony, Nikon, and Canon have all come out with large
sensor fixed lens cameras too

2. : Be practical
DSLR prices range from $500 to well beyond $1,000. If you’re new to
DSLRs, look for a camera in the sub-$1,000 range. They’ll have preset
shooting modes you can use while you learn how to master the manual
settings, and you won’t sacrifice much in terms of image quality. And, if you
do decide to upgrade to a more expensive camera body later, you can buy
a camera that takes the same lenses and accessories.
3: Body only: Many DSLRs can be purchased body-only and require that
you supply a compatible lens in order to take photos. Others—especially
entry-level models—also ship as part of a kit that includes a decent-quality
multipurpose lens. Kit lenses tend to be relatively slow, meaning you may
have trouble getting sharp action shots in low-light situations without a
flash. If you tend to shoot indoors, you may want to consider also investing
in a faster lens.
Features to consider
Lens selection:If you think you’ll want to use different lenses for different
shooting situations (like a zoom lens for distance shots, a macro lens, or
even a lens with an effect like fish eye), consider the lens selection for the
DSLR you're considering before you buy the camera. If the kit lens wouldn’t
be of much use to you, it may be more affordable to buy the camera body-
only and invest in the lens you really want.

Image stabilization: Even if you think you have rock-steady hands, it’s easy
to end up with blurry photos—particularly in low-light, indoor environments
where you don’t want to use a flash (in a church or a museum, for
example). In these situations, the shutter has to stay open longer in order
to create a good exposure. And the longer it stays open, the more
susceptible your image is to the effects of camera shake or subject
movement.
To help battle these problems, many camera manufacturers offer camera
and lenses that include image-stabilization technology. But there are
different approaches to image stabilization, each with its own unique
advantages and disadvantages:
Optical Stabilization Used in compact cameras and DSLRs, optical
stabilization is the most common image-stabilization method. Optical
stabilization uses gyroscopes within the camera or the camera’s lens to
detect camera shake, and then steadies the path of the image as it makes
its way to the camera’s sensor. In DSLRs, the gyroscopes are often located
in the lens.
Sensor Stabilization This technology works similarly to optical
stabilization. With sensor stabilization, gyroscopes located in the camera
body, rather than the lens, detect shake and then move the image sensor
to counteract the motion. Although it’s available on some point-and-shoots,
sensor stabilization is more commonly used in DSLRs

Digital Stabilization Unlike optical and sensor stabilization, which actually
correct the image while you’re capturing a picture, digital stabilization
attempts to make a picture clearer by simply changing the camera’s
settings or by altering the image after it has been captured. There are
several approaches to digital stabilization. One of the most useful is
Intelligent ISO. Used primarily in compact cameras, an Intelligent ISO
feature automatically increases the ISO, or light sensitivity setting when the
image sensor detects a moving object. As a result, the camera is able to
use a faster shutter speed to snap a picture, thus freezing the motion of the
5. 5
subject and reducing blur. A high ISO can, however, make images more
noisy.
Viewfinders Cameras come with three basic types of viewfinders: Optical
viewfinder (OVF), electronic viewfinder (EVF), and an LCD screen with Live
View. The first two are both eye-level viewfinders, while the third lets you
preview a scene on the camera’s LCD screen. Most current DSLRs have
an LCD screen in addition to an eye-level viewfinder. When evaluating a
camera, make sure its viewfinder is bright, that you can see from edge to
edge, and that the focusing screen is clear.

LCD with Live View Live View on an adjustable LCD screen is a great
feature for any time when you need to shoot over your head, down low, or
in other situations where your camera position makes looking through the
viewfinder impossible. If an LCD screen isn’t adjustable, Live View still
makes for more relaxed tripod-mounted shooting. Unfortunately, LCD
6. 6
screens can have reflections and glare, making them difficult to see in
bright light. Also, during Live View mode on most cameras, the SLR must
flip up its mirror. That means the camera loses its autofocus capability. To
calculate focus, it has to analyze the image that it’s seeing (Sony’s
translucent mirror technology solves this problem). This takes much longer
than normal autofocus, so when working with Live View you’ll need to
anticipate your focus concerns and adjust your shooting technique
accordingly.
Optical Viewfinder Optical viewfinders on DLSRs show exactly what the
lens sees, but often with a small amount of cropping around the edges.
They are the preferred choice for many pro photographers as they have all
the dynamic range of the human eye, and no lag time. They can sometimes
feel like you’re looking through a tunnel, though. The optical viewfinders on
more expensive (over $1,000) cameras are better quality.
Electronic viewfinder Found on many of the compact interchangeable
lens cameras, these viewfinders take up less space in a camera, which
mean a smaller and lighter body. They are projected video feeds, and as
such can have low resolutions. They also don’t show you the full dynamic
range of the scene, making it harder to make creative decisions about how
you want to expose your shot. They also have a slight lag time which can
be a deal breaker for sports photographers. What they can do is overlay
more information and show a preview of what an image will look like with
your chosen aperture, shutter speed, and ISO settings.
Flash When buying a camera, you’ll want to know what type of flash it has
and how much control it gives you over flash settings. Some DLSRs have a
small built-in flash, some have a hot shoe mount—a bracket that lets you
attach an external flash to the camera, and some cameras have both. If a
camera has a mount but no flash, check to see if an external flash is
included as part of the kit or if you’ll need to buy it separately.

A built-in flash is extremely handy to have, but it’s not going to be as high of
quality as an external flash. If you plan on using a DLSR camera for casual
photography or if traveling light is important to you, a built-in flash will be
useful. If you’re an advanced photographer who wants to greatly improve
the quality of your flash photography—and aren’t concerned about the heft
of the camera—take a hint from the pros and choose a camera with a hot-
shoe mount. This way you can attach external flashes, which throw light
wider and farther than built-in flashes can, producing more-consistent light.
They also raise the flash head above the lens, which helps reduce red-eye.
(Forget about using a camera’s red-eye mode for this—it’ll be more
annoying than useful.) Some external flashes even have rotating heads
that let you bounce the light off of ceilings for a diffused, natural look.
Finally, external flashes don’t drain your camera’s batteries, as they run on
their own battery source.

Make sure the camera you buy gives you quick access to different flash
modes, including On (which forces the flash to fire even if the camera
8. 8
detects enough light—useful for back-lighting situations), Off (to prevent
your flash from firing even in low-light situations), and Slow-Sync (which is
also sometimes referred to as Nighttime mode). This last mode is
particularly useful as it tells your camera to use a slow shutter speed in
combination with the flash, thereby preventing background detail from
getting washed out. If you don’t find this mode in the Flash settings, take a
look at the camera’s preprogammed modes. Some cameras also include a
nifty Flash Exposure Lock (FE Lock) feature. This lets you tell the camera
what the most important aspect of the scene is and then provides just
enough flash to illuminate it.
Autofocus While shopping you’ll read a lot about different autofocus
systems. The most common thing you’ll find is that some systems have
more “points” than others. This simply means that they can detect a subject
in more parts of the frame. More points are better, but the speed of the
autofocus mechanism is equally important. Also, DSLRs don’t have the
shutter lag that many point and shoot cameras have. Still, focusing a DSLR
requires pressing the shutter button halfway and can take varying amounts
of time on different cameras. If you can get a hands-on experience with a
DSLR before you buy, check the autofocus speed.
Continuous autofocus is a handy feature if you are photographing moving
subjects. Some new DSLRs now offer continuous autofocus while shooting
video. This is a great feature, but if you’re shooting without an external
microphone, your video might pick up the sounds of the lens refocusing.
Size A full-size DSLR is larger and heavier than other camera types, so
comfort is key. A camera that fits comfortably in one person’s hand may be
too large or small in someone else’s. If size and weight are a serious
concern, you may want to consider a compact interchangeable lens
camera, which have bodies as small as point-and-shoot cameras

Dust buster If you think you’ll be changing lenses often, look for a DSLR
with an internal sensor cleaner. This helps keep your image sensor clean
and dust free. If you’re using your camera in rugged, outdoor conditions
you may still need to manually clean your camera.
File formats DSLRs support raw file formats, which are un-processed files.
Raw files offer the most editing flexibility when you open the photo in an
image-editing program. However, if the camera is still relatively new, keep
in mind that you may need to wait for editing programs from third-parties,
such as Adobe and Apple, to support the camera’s raw format. DSLRs also
support the JPEG format, which all image editors can read, no matter what
type of camera takes the image. JPEG uses compression to create smaller
file sizes that won’t take up as much storage space as raw files, but do not
have as good image quality.

Continuous shooting mode If you take photos of sporting events, kids, or
any other fast, unpredictable subject, a continuous-shooting (or burst)
mode will make a huge difference in your photography. This mode lets you
hold down the shutter button to shoot multiple photos in rapid succession.
The number of pictures you can record in one burst is determined by your
camera’s electronics—and in some cases bythe type of memory card you
have. You may need a more high-speed memory card to take advantage of
your camera’s fastest shooting rate. If so, be sure to factor that cost into
your decision. To be effective, a continuous shooting mode should capture
images at least 3 fps (frames per second) or faster at the camera’s highest
resolution.
Face Detection With this mode turned on, your camera locates the people
in a shot and then fine-tunes the focus and exposure for those faces. While
this may sound like a superficial gimmick, we’ve found that it works
surprisingly well—greatly increasing your chances of getting good shots at
a wedding or family reunion. Typically, this option is in the camera’s
autofocusing (AF) menu. Face detection is particularly handy for candid
10. 10
shots, where you’re working quickly and are thus more vulnerable to
misfocused shots. It’s also a boon for flash photography. With face
detection turned on, the flash doesn’t try to illuminate the whole room, just
the people within range—cutting down on the nuclear blast effect.
Storage If you have an existing storage card that you’d like to use with
your new camera, make sure that it’s compatible with your new purchase.
Most cameras on the market today use SD (Secure Digital) or SDHC
(Secure Digital High Capacity) format cards. SDHC (Secure Digital High
Capacity) cards are more expensive, offering increased storage capacity
up to 32GB, but they’re not backward-compatible with standard SD slots.
SDXC, which supports storage capacities up to a whopping 2TB, are even
more expensive and they aren’t compatible with all SD/SDHC card slots.

Video Many DLSRs offer video recording features—often at HD resolution.
You’ll have to make some usability compromises that you wouldn’t have to
make if you used a camcorder but the video quality is often worth it. And
because you can take advantage of a variety of lenses, including fish-eye
lenses, you can achieve interesting video effects with an SLR. Remember
that video requires a lot of storage space, so plan accordingly.
In addition to storage capacity, there’s also the speed issue to consider. SD
and SDHC cards have a Decoding Class rating listed, which refers to the
data-writing rate for each card. The higher the Class number, the faster the
write speed; if you’re planning on shooting video or using a high-speed
burst mode, look for a Class 4 or Class 6 card at the very least.
To complicate matters further, there are a couple of other card formats out
there. Some cameras support MicroSD or MicroSDHC cards, a smaller
version of the SD card format that isn’t compatible with full-size SD slots.
Older Sony cameras take MemoryStick cards, and older Olympus cameras
use the XD card format; both companies’ new cameras now support
SD/SDHC cards. What’s more, many higher-end DSLRs have a larger-
format CompactFlash card slot. You’ll want to consider all of these options
when purchasing storage for your camera, though it is definitely easiest to
11. 11
go with standard SD/SDHC cards since you will be able to use them across
cameras.
Battery life Cameras use one or more of several types of batteries: AAs,
either non-rechargeable alkaline ($5 for four) or rechargeable nickel metal
hydride (NiMH, about $14 for four); high-capacity disposable CRV3s
(around $10 apiece, and some cameras take two); or proprietary
rechargeable batteries that can cost $25 to $65 to replace. Some digital
cameras quickly drain batteries—especially alkaline batteries—which can
be expensive and annoying. Battery life and cost often aren’t related; some
inexpensive cameras have great battery life, idea to buy spare and some
expensive ones use up a charge quickly.
Menus When evaluating a camera, consider how easily you can reach
common settings—resolution, macro mode, flash, and exposure
adjustments—and how easily you can play back just-taken images. Too
many buttons, and you waste time trying to figure out which button does
what; too many menus, and you waste time digging through them.

Compact interchangeable lens cameras These cameras are
part of a newer product category that sits between true DSLRs
and advanced point-and-shoots. The design of these cameras
omits the DSLR’s mirror chamber and moves the sensor closer to
the back of the lens. The lack of a mirror chamber allows for a
smaller camera body, while moving the sensor closer to the lens
allows for smaller lens design.
• All of this means that these cameras and lenses can be made
much smaller than those of a traditional DSLR, while delivering
the image quality of an SLR and the flexibility of using additional
lenses. However, this also means they lack an optical view
finder. Some cameras in this category offer an electronic
12. 12
viewfinder instead; others—particularly those at the smaller end
of the scale—lack even that and rely completely on the LCD for
framing shots.
•
• With all of the above factors to consider, it's impossible to
recommend the best cameras for everyone. Much depends on
budget, size, shooting style, and personal preferences. One
more thing: Prices vary wildly so it pays to check a number of
camera sellers before making the decision to buy.
