DSLR Camera Buyer’s Guide

Several important factors play an important role when buying a DSLR camera. First, you should know what type of pictures you intend to take with your new SLR. Today, most DSLR cameras can record videos in Full HD resolution or even higher, so many users purchase such devices to record videos.

Our comprehensive DSLR buying guide shows you how to choose the right camera for you and how to make your recordings even better. Aside from our comparisons, tests and reviews, which help you decide which device meets your needs, you also get tons of tips and tricks!

How Many Megapixels Does DSLR Need?

As the cameras get more sophisticated, the number of megapixels on their sensors gets smaller. These smaller pixels let in less light, which results in brighter, more natural-looking photographs. This is why SLR cameras with fewer megapixels acquire an advantage over pixel monsters.

Suppose you want to print your pictures on large canvases or posters. In that case, you should instead select models with the highest resolutions, which means that details are reproduced accurately, even in large formats without image errors. In that case, a camera with a large sensor with fewer pixels would be the best choice; the pictures would be more natural. On our large DSLR leaderboard, we have models with different specifications.

Which Camera Manufacturer Is The Best?

There cannot be a quick answer to this question because each manufacturer’s models have advantages and disadvantages. Most of the cameras are sold in Germany by Canon, Nikon and Sony. In addition to the design, the models differ primarily in software, whereby Canon and Nikon have clear parallels with respect to quality and quality. Pentax and Olympus can also be found in well-stocked electronics stores or photoshops, but these are geared towards professional users.

Especially for beginner photographers, it is very important to handle the actual camera to evaluate whether you like the controls or how the software works. Sony does not have an optical viewfinder, a device that is often a no-go for ambitious photographers.

For Beginners, the following features are essential.

Scene modes

Scene modes

A scene mode such as sports, portrait, macro, and landscape can help you achieve great results in various shooting situations. They are perfect for those just starting.

Pop-up flash

Pop-up flash


A pop-up flash unit is typically used when you need some fill-in illumination to prevent shadows on the face, like taking portraits on a sunny day. But it is less potent than a separate flashgun.


DSLR Viewfinder

Most DSLRs in this class are equipped with a pentaprism instead of a pentamirror. However, they should still have a sufficiently clear, bright and sharp display.

Live view

Live view

An LCD screen provides you with a magnified view which can be used to check focus accuracy when shooting manually. It can also be used to take pictures from challenging angles, such as standing on the ground. A swing-out LCD is therefore necessary. Nearly all cameras today have live viewing capabilities.


DSLR Construction

A lot of entry-level DSLR cameras have a plastic case over a metal chassis. Still, they should be sturdy enough for daily use. Some models feature a waterproof seal that can come in handy sometimes. Keep in mind, though, that the lens must also be waterproof.

Lens options

DSLR Lenses

The 18-55mm kit lens on DSLRs is the standard lens for beginners. You may have the option to upgrade for better quality, higher light, or a better zoom range. Such as the 18-135mm or the 18-200mm.

Main LCD


Different LCDs vary in physical size and resolution. Some have a swing-out facility, which is great when shooting from extreme angles.

Direct access

DSLR Buttons For Shooting Parameters

There is no question that direct-access buttons for configuring shooting parameters are convenient. They make it easy for you to change ISO, shutter speed smoothly, to focus in different modes, and more, so that you can keep your DSLR camera ready whenever it is needed to capture that perfect shot.

What is a DSLR?

What is a DSLR


From Wikipedia

Digital single-lens reflex cameras (DSLRs) are digital cameras that combine the capabilities and optics of a single-lens reflex camera with digital imaging capabilities.

A DSLR is a camera with a mirror that directs light from the lens to the viewfinder in a highly straightforward language. As discussed before, you view your subject through the viewfinder before you shoot.
The great thing about SLR technology is that you can see exactly what you are taking through your viewfinder.

DSLR cameras consist of

How A DSLR Works
  1. Lens
  2. Reflex Mirror
  3. Shutter
  4. Image Sensor
  5. Matte Focusing Screen
  6. Condenser Lens
  7. Pentaprism
  8. Viewfinder




How does a DSLR camera work?

You’re getting ready to press the shutter button when you look through your viewfinder and take a picture of the scene.

Light passes through your lens, hits the reflex mirror (2), which sits at 45 degrees inside the camera body, and then gets forwarded vertically to an optical element called a pentaprism (7). A pentaprism converts the forwarded light from vertical to horizontal light using two separate mirrors (2). The converted light then strikes the viewfinder (8).

When the shutter button is pressed, the reflex mirror (2) swings upward, resulting in direct light flow to the image sensors (4). The shutter (3) closes, and the reflex mirror (2) returns to its 45-degree angle to continue redirecting light into the viewfinder (8).

Next, the camera goes through a lot of complex processing. All DSLR cameras feature a processor that takes the image data from an image sensor, converts it into a convenient format, and writes it to a memory card.

The entire process takes only a few seconds. It also depends on how much processing the camera needs to do on your image. Some Pro DSLRs can do it up to 12 times per second.

Best DSLR Buying Guide


The first thing you’re likely to hear about DSLR cameras is how many Megapixels they have. Megapixels are the number of actual pixels within the digital image. Mega means million, which means a 10-megapixel camera has 10 million pixels.

One common misconception is that higher megapixels imply higher image quality. However, a single pixel is the same size regardless of size. Choosing a 14.5MP camera over a 10MP camera means you will have more pixels in your picture – other factors affect the quality.

Two photos with different pixel counts will illustrate the difference between the two images. A 10-megapixel photo is 3888 by 2592 pixels, while a 14,5-megapixel image is 4672 by 3104 pixels. The difference between the two images is in size, not the quality.

If you plan to create giant images, then a higher megapixel camera is what you need. If your pictures are for a photo album or online sharing, then a lower-megapixel camera will catch your attention. Remember, the more pixels your camera offers, the more you pay.

Processors and Sensors

You and most other people wonder what in the world is a CMOS sensor? Right behind the megapixel rating of a DSLR camera comes the sensor and processor type. These bits of information, as obscure as they may be, can make a big difference in the photos you take.

The CMOS sensor is responsible for collecting the image data and passing it on to the image processor. In a DSLR camera, when the shutter is released, an image is captured by the sensor; when with a 35mm film camera, the idea is picked up on the film.

Once the sensor receives the information (the image), it must be transferred to the image processor: the faster the processor, the better the camera’s performance and picture quality. A camera’s speed can be seen in the number of frames per second it can shoot and the camera’s overall performance. High-end cameras have faster processors and even dual processors to quickly process and handle large amounts of data.

Combining a fast-moving sensor with a slower processing unit often result in a camera that will not provide the results you need. Again, it depends on what you’re looking for in a DSLR.

ISO Sensitivity

It’s another one of those terms that seem overly technical and unimportant. ISO, though, could be one of the most important features of any camera. The ISO number indicates how quickly the camera’s sensor absorbs light and can make or break a great shot.

The lower the ISO, the slower the sensor absorbs light, so if you wanted to display a mountainside in bright sunlight with a low ISO (100), then a high ISO (3200) would be necessary. However, using a low ISO setting in a dark environment results in blurry images; there is a trade-off. The higher the ISO setting, the more grain or splotches appear in the picture.

Today’s DSLR cameras come with ISO settings ranging from 100 to 6400, and some even have 12800. The camera you choose will be determined by how and what you intend to shoot. If you plan to shoot mostly outdoors, then a lower ISO range will do. But if you plan to shoot in lighting conditions from bright to dim, then a high ISO range will be best.


One good lens can make a big difference in how your photograph comes out. Lenses affect the colors, focus, contrast, and so much more. The beauty of DSLR cameras is that you can switch lenses for different subjects and effects. It is essential to take into consideration the mounting method of your DSLR when purchasing one. Are the lenses readily available? What kind of lenses are there? How much do they cost? These are the types of questions you should ask when considering your DSLR purchase.
