Mirrorless vs DSLR

Mirrorless vs DSLR

Our article today is about mirrorless vs DSLR, the design of DSLR and mirrorless cameras, and the best kind of shooting you can get out of DSLR and mirrorless cameras.
We will talk about the pros and cons of mirrorless cameras and DSLRs.
How to choose the best type for you?
First, you need to know that you will be able to get excellent results with both types, whether you use DSLR and mirrorless cameras, or just one of them.
But you must understand that DSLR cameras and mirrorless cameras have their advantages and disadvantages.
To make it clear from the get-go, mirrorless cameras are the future.
As I always say, the best camera for you is the most appropriate camera for the nature of your work, and it does not have to be the best thing or the latest thing, to be the most appropriate for you and your needs.
DSLR and mirrorless cameras, as I said, have their advantages and disadvantages, but to understand the topic more, we must understand the nature of the work of DSLR and mirrorless cameras.

DSLR

The design of DSLR and mirrorless cameras is also different.
The DSLR is the oldest, and the name itself hints at how the camera works.
DSLR is short for Digital Single-Lens Reflects, and so the acronym of the four words is DSLR.
First, the sensor will be electronic or digital, in contrast to the old cameras that used film, and of course, the camera has only one lens, and this is the meaning of the two letters SL, and the most important letter is the last letter R, which is Reflected.
This means that the light is reflected by a mirror in front of the sensor.
The light enters the camera through the lens, and after that, they get a reflection through the mirror in front of the sensor.

   This is what allows you to see the image through the viewfinder at the same time, reflecting the light down to flicker in a special sensor to adjust the focus, but the main and important point here is that when you look in the viewfinder, you see the light that entered the camera through the lens directly, and the viewfinder here is called the Optical Viewfinder. Which means there is no electronic processing of the image you are seeing, and when you press the shutter button to take the picture, the mirror in front of the sensor raises it, and the lighting falls directly on the sensor.
So you can take the picture you want, and this system in photography, which is shooting with a DSLR camera using the Optical Viewfinder, has its advantages and disadvantages, but what we are talking about is the way DSLR and mirrorless cameras work.

Mirrorless Camera

The way mirrorless cameras work, through interpreting the name, mirrorless cameras, as you may understand, are mirrorless DSLR cameras, and since the mirror is removed, this means that you do not need the prism that is in the viewfinder, and this also means that you do not need the special focus sensor that was kept under the prism.
Therefore, the light inside the camera through the lens will fall on the sensor directly, which means no reflection of the light will occur.

So, when you are looking at the viewfinder, you will see the picture. When you look at the viewfinder, you will be staring at an electronic screen. I mean, it is not in the Optical Viewfinder, it remains in the Electronic Viewfinder.

DSLR VS Mirrorless for Video

Before we talk about any details, if your whole job is to shoot a video, even if you use a DSLR camera, you use it as if it were a mirrorless camera.
 Because when you shoot a video with a DSLR camera, you enter a setting called Live View.
 This means that the mirror in front of the sensor is raised, and this prevents you from using the Optical View Finder.
Because the light falls directly on the sensor.

In short, since the mirror rose and continued to use the camera through the screen in the back, you thus turned your DSLR camera into a mirrorless camera.
You should choose a mirrorless camera as long as your work is all video, and the same is true for people who shoot photos with a DSLR camera but use Live View as long as you do not want to use Optical. There’s no need for DSLRs.

Mirrorless VS DSLR Size

Even if you’re a big fan of viewfinders, the best option for you remains to be choosing a mirrorless camera because they do not have a mirror, a prism, or a sensor under the prism, specifically for adjusting the focus. DSLR and mirrorless are also different in size. We find that mirrorless cameras, in general, are smaller in size and significantly lighter in weight compared to DSLR cameras, so if the size is small and lightweight is a priority and important to you, It remains the most suitable for you, so you’ve got to choose a mirrorless camera.

So Which Is Better DSLR or Mirrorless?

Before we explain the advantages or disadvantages of DSLRs and mirrorless cameras, we must make it clear that mirrorless cameras are generally the best when it comes to design.
This does not mean that mirrorless cameras are better for you, but it does mean that mirrorless cameras are better technically.
And when I say technically, this means that mirrorless cameras are supposed to give you better results, at least in terms of sharpening or image accuracy.
And by the way, this is scientific, not just me blabbering.
DSLR and Mirrorless: Which one takes sharper photos?
The issue is very simple.
When they removed the mirror that was between the last lens and the sensor, it allowed them to make a new design for the lenses.
This new design made them move the lens closer to the sensor, and the distance between the end of the lens and the sensor is called the flange distance, and scientifically speaking, the shorter the flange distance, the better pictures you will get in general.
Therefore, when we compare mirrorless cameras with DSRL cameras, we will find that the flange distance is always shorter.
This means that mirrorless cameras will let you get better pictures in general, especially in terms of sharpening and image accuracy.

Pros and Cons of Mirrorless Cameras

Mirrorless Cameras Cons

1- Shortage of battery life:
In order to understand why this happens, we must know that first the processing and, secondly, the viewing affect a third very important thing, which is the battery life.
As we explained in mirrorless cameras, light enters the camera through the lens and falls directly on the sensor. The first light treatment must take place, and then you can see the image through a screen, whether it is an electronic viewfinder or the screen on the back of the camera.
Therefore, as long as you can view the photo on the screen, this means that the camera continues to process light, which means that the camera continues to use the battery due to the continuous processing and the continuous display on the screen.

The most significant disadvantage of mirrorless cameras is their battery life. The battery life is often less compared to DSLR cameras, because in DSLR cameras, as long as you use the optical viewfinder, the camera consumes almost no power at all.

2- Another defect in mirrorless cameras, is the delay of Image Processing

The delay between the light falling on the sensor and the display of the image you see on the screen is because the image you see is a treatment of the light that falls on the sensor.
This means that you will often notice a delay between the light falling on the sensor and the display of the image you see on the screen, and the delay period depends on the power of the processor in the camera.
If the camera has a powerful processor, the delay will be barely noticeable and may remain so small that it may not be noticeable, which is, of course, the case with expensive mirrorless cameras.
But if the processor performance is weak, like the one found in cheap mirrorless cameras, the delay will be more noticeable.

3- Another problem is the quality of the image that you see.
Whether through the screen on the back of the camera or the electronic viewfinder.
The problem is as follows: If you want to see a picture of excellent quality, the camera screen must have an excellent quality. This will often be very expensive and often use a lot of battery power.
But regardless of the battery problem, the real problem is with the quality of the screen on which you see the image. If you use a cheap or economical mirrorless camera, the electronic viewfinder will often be somewhat poor and you will often have to rely on the screen on the back of the camera.
This screen is often not going to be nice and strong in high light conditions when you shoot in the daytime. On the other hand, if you are using a DSLR camera, you will find that the Optical View Finder will show you a very clear and sharp image, because you see exactly what’s in front of you with no treatment whatsoever, especially in extreme lighting conditions when you shoot in the day.

Mirrorless Cameras Pros

At the same time, concerning mirrorless cameras, you will find that the electronic viewfinder has a very awesome feature, which is that the image exposure will be displayed according to your settings, and this is something that you cannot get when you use an optical viewfinder.

electronic vs optical viewfinder


For example, if you use a DSLR camera in a place where the lighting is very weak, if you look in an optical viewfinder, you will find that the image is dark because the lighting is very weak, and even if you raise the ISO sensitivity or reduce the shutter speed, the result you see in the optical viewfinder will remain as is.
 The only thing that will be affected in the image is the aperture, but other than that, if you change the ISO or change the shutter speed, there will be of no change to the image you see through Optical Viewfinder.
But if you use a mirrorless camera in a place where the lighting is poor, the image exposure will be displayed according to your settings.
Therefore, for every variable in the ISO or shutter speed, you will find that the image exposure changes simultaneously, and you can see with your eyes the change directly even before you take the image.

Disadvantages of DSLR Camera

There are two problems with DSLR cameras due to the reflection of light more than once.
Because of mirrors and prisms, the two problems are related to one thing, which is focus.
This is one of the biggest differences between DSLRs and mirrorless cameras.

1- is that the focus is frequently not set to the desired location, and you suffer from Back Focus or Front Focus.
We said that light enters the camera through the lens, but the light does not fall directly on the sensor but rather gets reflected by the mirror located on the sensor, and after that, it gets a second round of reflection through the prism in the viewfinder. The prism is what allows you to see the light through the viewfinder and, at the same time, it reflects the light downwards so that it falls on a special sensor to adjust the focus.
Here, the camera sees whether the focus is correct or not through the special sensor located under the prism, not through the main sensor behind the mirror.
Therefore, when you come to adjust the image and press the shutter button, the mirror looks up and the light falls on the main sensor, but due to the movement of the mirror, a slight vibration occurs, and due to the reflection of the light more than once, we find the actual focus that you are getting will be somewhat different from the one you wanted to set.
So the result is that you will get something called “Back Focus” or “Front Focus,” and Back Focus means that the actual focus is further than the focal point that you wanted.
As for “front focus,” it means that the actual focus is ahead of the place of the focus that you wanted.

Front & Back Focus


 Of course, this problem has a solution, and you can solve it by adjusting the lens or adjusting the camera, and this adjustment is made to take into account the difference between the actual focus that you are getting and the one you wanted to finally get.

2-  Is that there is a limited number of focus points, and all the points are confined to the middle of the frame only. On the other hand, these two problems just do not exist when it comes to mirrorless cameras.
This is because the DSLR cameras have 2 sensors; one dedicated to adjusting the focus through the viewfinder, and the second is the main sensor behind the mirror.
Thus, when you use the Optical Viewfinder in DSLR cameras, you will find that the number of focal points is very limited, and often you will find that all the focus points All points are confined to the center of the cadre only, but again, this problem does not exist at all in mirrorless cameras because the focus is determined by the main sensor itself. Therefore, it is very easy for us to take advantage of the entire sensor space to locate the focus.

Dslr vs mirrorless focal points


And that is why we can very easily set the focus on almost anywhere in the cadre. Not only that, we find in mirrorless cameras modern focus technologies such as eye detection autofocus.
I mean, the camera can recognize not only the face but also the eye and adjust the focus on it, and not only that, there are cameras that can recognize the faces of animals and they can recognize the eyes of animals, but this technology is still a little modern and there are problems and bugs that are under development.

Eye Detection Autofocus


And due to the presence of modern technologies in determining the focus, especially in determining the face and eyes with the most accuracy, mirrorless cameras will be the ideal choice for people whose job is mostly to photograph people in general or portraits.

DSLR vs Mirrorless

In the end, we can summarize what we said in the following:
Shooting with DSLR cameras depends on the Optical Viewfinder, and this system in general preserves the shape of the battery, and the Optical Viewfinder shows you a very clear and sharp image, especially in strong lighting conditions when you shoot in the daytime. By using the optical viewfinder, you prevent any delay at all.
But in general, DSLR cameras are larger in size and heavier in weight, and often you will find yourself unable to get that sweet focus you desire, and end up with a front or back focus, and the number of focal points will be very limited.
And they will be pretty much confined to the middle of the cadre.
As for filming with mirrorless cameras, it depends entirely on the electronic system.

This in general reduces battery life, but in the end, it makes you get better pictures because the flange distance is much less.
This allows you to get better pictures in general, and since mirrorless cameras are completely dependent on the main sensor, this makes us use the entire sensor space to be able to determine the focus, and this will allow us to obtain newer technologies in determining the focus, such as eye detection autofocus and animal eye detection autofocus. The electronic viewfinder allows us to define the image exposure very accurately even before we take the picture, but unfortunately, we may notice a delay or delays during shooting, and you often have to buy a somewhat expensive camera to avoid lag while viewing photos on the back screen or the electronic viewfinder.

Why Are Mirrorless Cameras Better?


In the end, I would like to say that all the defects or problems of mirrorless cameras will surely be resolved in the future.
If battery life is the main problem in Mirrorless cameras, surely battery technology will be much better in the future, or you can simply buy more than one battery or buy a battery grip to increase the battery life.
At certain settings, you can adjust them in the camera to preserve more battery life, and surely in the future, the camera’s processor will be much stronger, and at the same time, surely processors will consume less power or use energy more efficiently, and certainly.
In the future, the display methods will be much better and better, and certainly, energy will be used with higher efficiency. That is why I say that mirrorless cameras are the future because all their problems are solvable in light of the terrible technological development that we are living in, and surely the moment will come when big companies will decide DSLR cameras have to be discontinued. and most specialists now say that big companies will take this decision soon, and this is because they want to harness their full potential in developing mirrorless cameras.
Of course, Sony has long been very interested in mirrorless cameras and is considered the number 1 in the market now. It is also clear that Canon is also following the same path, and most people think that Canon is the one who will invade the mirrorless market with its new R-series cameras and, of course, Nikon B.
It is trying to catch up with Canon and Sony with its new Z series cameras.
All I am saying does not necessarily mean that mirrorless cameras are the most suitable for you now, but I think that after this article you will be able to choose the most suitable for you based on the advantages and disadvantages of DSLR And Mirrorless cameras.
