Best Guide On Everything You Want To Know About DSLR Cameras

Do you know how to choose and buy a DSLR camera in 2020? What digital camera should you buy? What is the best camera? Should we buy a compact camera, professional SLR, DSLR, Bridge, EVIL, adventure camera, analog, superzoom?
Here is the Best guide on everything you want to know about DSLR cameras.

Buying a suitable camera for each of us has never been an easy task. There are no good or bad cameras, but cameras suitable for each situation. In 2020 manufacturers do not make it easy for us to choose the best model …

We will see all the types of cameras available in 2020 and some fundamental parts of their operation.

Guide For Buying A Good Digital Photo Camera

  1. Try it before you buy it: you have to feel comfortable with it, have the controls you need, a sufficient grip, easy to use menus, etc … and then check that its online price is cheaper than physical stores, and buy it from your home.
  2. Do not become obsessed with buying the best camera: No camera is “the best” in all sections (photo quality, performance, functionality, and design). Try to fit as much as possible to your needs.
  3. No specification will tell you which camera is the best: better zoom or higher resolution are not indicative of one camera is better than another.

DSLR, EVIL or advanced compact digital cameras?

A DSLR or DSLR has a mirror that reflects the image of the lens, usually through a prism to an optical viewfinder. An EVIL or CSC camera instead of having a mirror that reflects the light sends the image directly from the sensor to the viewfinder or to the rear LCD screen. Essentially it is the technology of a compact camera, but with the possibility of changing the lenses.

EVIL vs. compact: EVIL cameras tend to be better than compact cameras because they have larger sensors. On the other hand, they are bigger and the lenses cost a lot of money.

EVIL vs DSLR: if you need a good battery life or a good ignition speed, DSLR models are more suitable. Low-end DSLRs are cheaper than EVIL cameras. In contrast, EVILs usually have better video modes and can almost do the same things as DSLRs.

Key features in a digital photo camera in 2020


The resolution of a camera is usually measured in megapixels (MP). This number indicates the number of pixels that the camera uses to produce an image. All cameras usually have enough MP, but many of them do not have sufficiently powerful processors to deal with images.

Lenses (objectives)

There are two important characteristics in relation to the objectives: aperture and focal length.

The focal length of the lens, measured in millimeters (mm), tells us what the magnification of the image is and the amount of scene covered by the lens (the viewing angle). As the focal length increases, things look bigger and occupy more. A lens that covers multiple focal lengths is a zoom lens, and the zoom specification is the ratio of the longest to the shortest focal length: a 20-100mm lens, therefore, has a 5x zoom.

  • Ultra wide-angle (less than 18 mm) is good for capturing large scenes.
  • Wide-angle (around 18 mm to 30 mm) is good for landscape and street photography photos.
  • Normal (about 30 mm to 70 mm) is good for portraits and snapshots.
  • A telephoto lens (around 70 mm to 300 mm) is ideal for portraits or sports.
  • A super-objective lens (more than 300 mm) is good for sports or nature.

You have all the details about the types of lenses for cameras in the following entry:

The opening is the size of the opening that the light passes through and is referred to as number f. The smaller the number, the larger the opening. When the specification appears as 18-55mm f3.5-5.6, that means that the maximum aperture is f3.5 at 18mm and 55mm at f5.6. The wider openings let in more light and give you more control over the depth of field. A lens with a wide aperture is known as fast and one with a narrow aperture as slow. Fast lenses are considered better than slow lenses; “Fast” and “Slow” have nothing to do with focus performance.

It may interest you:

This is something important to keep in mind if you decide to buy an EVIL camera (CSC) or a DSLR (SLR): Do you know which system has the lenses that interest you most? Normally Canon and Nikon have behind a wide bag of lenses that you will be able to use, but Sony is treading very hard with its mirrorless cameras, and more and more lenses are available for its cameras, both of its own manufactures, as of other manufacturers.

What if you have to be clear, is that once you get into a system, it is very difficult to get out of it … Are you going to miss all the objectives you have bought for a particular system? Think about it before buying a camera with these features.

Sensor size and type

With the size of the sensor we mean the dimensions of the array of photoreceptors that create the pixels that become an image. Larger sensors generally produce better photo quality, but the larger the sensor, the larger the camera; A larger sensor also requires a larger, more electronic lens. Larger sensors are also more expensive and increase the price of a camera.

What sensor technologies can we find? 

  • CMOS is the most popular. A variant, BSI CMOS, is popular for compact cameras, as it allows greater sensitivity in low light over a relatively small part of the sensor.
  • The cheapest compact cameras still use CCD sensors. Cheap CCDs do not offer as good image quality as the more expensive CMOS sensors, but on the contrary, more expensive CCDs like those used in medium format cameras produce better photos. In general, CCD sensors do not offer a good video.

ISO sensitivity

The sensitivity of the camera to light is called ISO sensitivity; The higher the number, the better the camera will shoot in low light conditions. However, as the sensitivity increases so does the amount of noise. As a result, few cameras are able to use the highest ISO sensitivity. Rating ranges, making a reliable specification. For example, a camera that has up to ISO 6400 will probably produce decent images up to ISO 800.


The most advanced camera models still have viewfinders. They are useful when it is difficult to see the LCD screen with sunlight.

There are basically three types of viewers:

  1. Viewfinders that give you a direct view of the scene (TTL)
  2. EVF or electronic viewfinder
  3. TTL optical viewfinder in digital SLRs.

EVFs have a certain advantage when recording video since you can see what you are recording simultaneously (with an optical viewfinder not). On the other hand, optical viewfinders are better for recording action scenes, since an electronic viewfinder can only show the action once it has passed, not while it is in progress.

Important specifications? The viewfinder coverage in the percentage of the amount of the scene can show: 100% is better, and effective magnification, which tells us how big the image looks in the viewfinder. A good viewfinder will also have a diopter adjustment for those who wear glasses.

Image Stabilizer

Image stabilization prevents camera shake. There are two types of optical image stabilizers :

  • Located in the chamber
  • Located in the lens

They work similarly, but those located on the lens seem to work a little better during video shooting, but those that are located on the camera are more comfortable when changing lenses with or without a stabilizer.

Cheaper cameras have an electronic stabilizer, which uses a combination of fast shutter speed and higher ISO sensitivities to help adjust the movement. Unfortunately, this increases image noise and is less effective in low lighting.


Most cameras use rechargeable lithium-ion batteries. They offer a longer battery life than AA batteries but are generally designed for a camera brand. There are models that use AA batteries, but they are generally low-end compact and mega-zoom cameras.

When buying a camera you have to verify how many shots you hold without having to recharge the battery.

On the other hand, it is very normal to use this type of rechargeable batteries in the flashes. That’s why we have recommended the best rechargeable batteries:

Continuous Shooting Rate

A measure of the number of images per second (FPS) is capable of capturing a camera. In optimal conditions, we want a high SPF, at maximum resolution, with autofocus and automatic exposure. But companies often play with this value to make us believe that it is higher than it really is in a normal situation.


To record good videos, the minimum we need is 1080 / 30p – «1080» refers to the resolution 1,920 × 1,080 pixels, also known as Full HD, while «30p» refers to 30fps. If a camera offers a frame rate greater than 60 fps, it will allow us to create slow-motion videos. If a camera has 4K video resolution, then much better, it is 4 times higher than Full HD.

As for codecs, the algorithms that compress and decompress the video, we will look for a codec such as H.264, AVCHD or XAVC, which are subsets of the MPEG-4, instead of Motion JPEG. Current video files have formats such as MOV, AVI, MP4, and MTS.

Video recording also has a bit rate, the amount of data it encodes per second of video: the higher is generally better.

But if you want to record in spectacular video quality, you have to do it in 4K resolution. There are already relatively sweet potato cameras that record in this resolution, such as the Sony a6300:

Camera modes

Non-professional photographers normally use Auto mode, in which we let the camera calculate all the parameters of the photo. Professionals use the manual modes that allow us to control all the parameters of the shot. There are many modes available that vary or not certain camera parameters, as well as scene modes that vary from one manufacturer to another (sport, landscape, macro, portrait, panoramic, etc …)


It is increasingly requested that the camera has WIFI to wirelessly transfer our photos to the smartphone, computer or tablet. If we also have built-in GPS, we can position our photos.

The downside that has the use of these two characteristics is that they consume a lot of battery.

9.- Canon vs Nikon: Comparison between the cameras of both companies

It is clear that these two brands are two of the best in the world, and I better love it is somewhat complicated to decide on one or the other. eye! Sony is also hitting hard in the world of DSLR cameras, so you should also value the models of this company.

Canon DSLR vs Nikon DSLR? Are Canon or Nikon digital cameras better? And its objectives? Is there a lot of difference between your prices? Do you need a good comparison of SLR cameras? Probably the two reference companies in the manufacture of cameras are Canon and Nikon. Over the years they have maintained an interesting pulse for trying to be the brand with better models and with greater acceptance among all photographers in the world. We present a comparison of the DSLR digital cameras (SLR) of both companies.

Is there a clear winner? Well, the truth is that you can never generalize. Depending on the needs of each one we will find the best solution in Canon or Nikon. But what is clear, is that once you have opted for one of the two companies, it is very complicated that we move to the other, especially due to the strong investment in objectives that we have surely made over the years, and that, of course, are not compatible with the opposite brand.

To help you decide which of the two companies is the most suitable for you, we have written a few articles comparing the main features of their cameras:

In this post, we make a really important review of all the models by price range. You must keep an eye on him.

10.- The best cameras for less than 400 euros

Do you need a good camera for less than 400 euros? Not sure which are the best cameras for quality price?  Many times we don’t need to spend a lot of money to find very good cameras. You can find DSLR, EVIL (CSC) models, and compact cameras.

We talked about a few cameras that can be the perfect point for amateur photographers:

  • The Olympus E-PL5 achieves the best balance between features, price and image quality among these 6 models. It is small enough to take anywhere, it is easy to use, it has enough creative modes and a very good image quality.
  • Secondly, we find the Nikon D3400, which is a totally different camera than the previous one. It is a DSLR with a solid construction, great handling and offers a very good image quality. Guided shooting mode is ideal for beginners, but has many options for advanced photographers on a tight budget.
  • If you want something more compact you can opt for the Panasonic DMC-TZ80 or the Sony Cyber-shot DSC-HX90V: they are perfect to take on a trip with you and their photographic quality is undeniable. The Sony A5100 is an attractive camera in its range, although its images are a bit worse than those of the other cameras. If you want something better go to the a6000, which is still reasonably priced.
  • If you just want to record some video and carry a small camera on your trips, the GoPro model is perfect for you.

11.-Adventure or action cameras

This category is very special because they are usually cameras that we will use to record videos (although they can take very decent photos). You probably sound like GoPro models, but there are many other manufacturers that have put on the market very good action cameras. We recommend a few models in the following entries:

  • The 10 best submersible actions (adventure) cameras with 4K recording: What adventure camera models are worth considering this year? Submersible and video recording models in 4K resolution? Things have not changed much compared to the previous year and our recommendation is still directed mainly towards the cameras of a company: GoPro (which does not take away so we recommend two other models). GoPro continues to offer the latest technological advances, and the price of its cameras has been reduced in recent months. That said, Garmin and Xiaomi also offer two very interesting models.
  • The new GoPro Hero cameras: Which one is the best for me? : Do you want to know which is the best GoPro HERO camera for you? Right now we have the GoPro HERO 4 versions and the new and more modern GoPro HERO 5, GoPro HERO6 and GoPro HERO7 Black, Silver, and White. What is the best GoPro in 2020? We are going to tell you what is the best option for you like a video camera for your adventures.

12.-Drone with camera

Nor can we forget the cameras present in the drones that fly from side to side these days.

We are going to recommend professional drones, cheap drones with cameras to start in this world and finally a few drones for children. Nor do we forget the best drones for initiation in this world.

13.-360º cameras

And the 360º cameras that record everything around you? What types of 360 cameras are you going to find? Normally two types of models: 360º action cameras that resist falls and can be submerged in the water in many cases, and 360º cameras to carry on quiet trips and that fit the pocket. There is some model that you can even connect directly to your iPhone.

Do not forget to buy good photography accessories for your camera

Very important. A good camera is worth nothing if you don’t have good SD cards, a good tripod, or a good bag to put your photographic equipment. We have a few recommendations to make.


It does not seem easy to buy a new digital camera in 2020 due to a large number of options we have in the market, but everything will become easier if you know yourself and know what you want to use your new camera for. It is not necessary to spend a lot of money to buy the camera that best suits your way of being and taking photos.
