In today’s review, we will be comparing two professional Sony full frame sensor cameras: Sony a9 vs a7II.
Our comparison of the Sony a9 vs Sony a7II is quite lengthy. So, if you need the information to make a really quick decision, the next three sections are for you.
We, however, encourage you to read on to the very end if you can. The thoughts of customers who have used these cameras and our take on them are contained in the last two sections of this review.
Comparison Overview – Sony a9 vs a7II
This section is divided into 4 major subsectors to help you better grasp this summary. Without further ado, let’s zoom right in.
Where Do They Both Get It Right – Sony a9 vs a7II?
Sony graced the two cameras in comparison with incredible sensor resolutions. They both have 24 megapixel full frame sensors, a sensor size which is the favorite of professionals.
When it comes to shooting in challenging weather conditions with these cameras, Sony has got you covered.
This is because these cameras come with environmental sealing, which ensures their resistance to water and dust particles.
Another thing these two cameras got going on for them is the presence of built-in stabilization. This reduces the likelihood of shooting blurry images.
The Sony a9 and the a7II come with electronic viewfinders which have great resolutions. This guarantees that what you see while shooting perfectly matches what you get later in the image.
The LCD screens on these cameras are articulating screens. This will allow you the freedom to shoot from different flexible positions.
Also, both cameras under review come with built-in wireless connectivity. This makes the transfer of photos from the camera to nearby compatible devices easier.
The Sony a9 and the a7II both have RAW Support, so you are sure to have better image quality when you shoot in RAW with either of the cameras.
Another great thing going on for these cameras is that they both have a great shutter speed of 1/8000 seconds.
They also provide better video recording control, as they come with microphone port and headphone port.

Where Do They Both Get It Wrong – Sony a9 vs a7II?
For reasons best known to Sony, neither the a9 nor the a7II was made with a built-in flash. This means they both require that you use an external flash on them to improve lighting.
Also, as with almost all full frame cameras, these two – Sony a9 vs a7II – are bulky.
How Do They Differ From Each Other – Sony a9 vs a7II?
An important difference between the two cameras is the presence of a touch screen on only the Sony a9 which makes it the easier to control.
In addition to that, you can connect to other devices via Bluetooth with only the Sony a9, as the a7II does not support the feature.
Further, while the a7II has just 117 focus points, the Sony a9 tops that with a very impressive 693.
Concerning battery life, the Sony a9 offers you 300 shots more than the a7II’s 350 per full charge.
Action photographers appreciate a camera with fast continuous shooting, and while both cameras under review allow this, the Sony a9 is 15 frames per second faster.

What’s The Price/Value Like – Sony a9 vs a7II?
The Sony a9 and a7II are high-end cameras. This is not surprising, seeing as they have full frame sensors.
Anyway, it is important to point out that the a7II is the less expensive one of the two cameras, and by far, too.
The a9 is a very expensive camera, and yes, it does wonders, but we still think it could have been made a little more affordable.
This camera is 4 times the price of the a7II, but we don’t think that there is a commensurate difference in performance levels.
This is why we think that the a7II is the one with the better price/value ratio. The a9 might be more dazzling, but we think the a7II will give you more value for your money spent.
Brand Strength – Sony a9 vs a7II
For high-quality cameras, whether they are for beginners, enthusiasts, or pros, Sony is a brand you can trust.
Sony, which has been declared the producer of the world’s best image sensors, is a major player in the market for cameras.

What Do They Have In Common – Sony a9 vs a7II?
Since we are done with giving you a quick summary, we will move headlong into more details from this point on.
In this section, we will focus on some of the features which the Sony a9 and the a7II have in common.
Some of these features will be the same, while others may differ slightly.
Maximum Sensor Resolution
Sensor resolution is one of the most popularized determining factors of a camera’s worth. And with these cameras – Sony a9 vs a7II – Sony didn’t disappoint at all.
They both come with 24 megapixel full frame sensors. However, they differ slightly in size.
While the Sony a9 has a 35.6 x 23.8 millimeter-sized BSI-CMOS sensor, the a7II has a 35.8 x 23.9 millimeter-sized CMOS sensor.
Therefore, with these cameras, you are sure that even images that are cropped or blown out won’t lose sharpness nor details once they are printed.
Built-In Image Stabilizer
When using a camera that comes with built-in image stabilization, the likelihood of shooting blurry images is greatly minimized.
How this works is that the camera’s lens is automatically steadied against vibrations or movements in the camera’s position.
Fortunately, each of the cameras under review come with a 5-axis sensor-shift image stabilization. The Sony a7II has been acclaimed to be the world’s first full frame camera with this technology.
The 5-axis technology reduces blurs caused by camera shakes from 5 different directions – horizontal, vertical, pitch, yaw and roll.
Even as you run or walk while shooting, this stabilizing system that is present in the Sony a9 and a7II has got you covered.
Your mounted lenses can also utilize this built-in 5-axis image stabilization.
A viewfinder is that part of a camera where you look through to correctly focus and compose your picture before shooting. There is the optical viewfinder and then, there is the electronic viewfinder.
Using the viewfinder helps to reduce the need for cropping your images later, as it will ensure the image correctly fits within the frame.
With the electronic viewfinder, you see exactly how the image will look when shot, compared to optical ones which show you images exactly how they are.
We are all for technological advancement, and so is Sony with an electronic viewfinder on each of the a9 and a7II.
Both cameras have the same 0.5-inch size OLED electronic viewfinder with a 100 percent coverage. However, they differ slightly in resolution and magnification.
The Sony a9 has a viewfinder with a resolution of 3,686k dots, a 0.78x magnification, and a refresh rate of up to 120 frames per second.
On the other hand, the a7II has an OLED electronic viewfinder with a lesser resolution of 2360k dots, a 0.71x magnification and a refresh rate of 60 frames per second.
To ensure optimal performance and durability of your camera functions, proper care needs to be given to it.
If you are more inclined towards outdoor photography and travel photography, you will agree that your camera should not be left unprotected from the elements.
But with environmental sealing, your camera is provided with added protection against the negative effects of the elements.
An articulating screen is an LCD screen that is not fixed but can be turned in different directions without turning the camera body.
This type of screen allows you to shoot from various positions. Talk about creative shoots!
The articulating screen is one of the prominent features of each of the Sony a9 and the a7II. Both cameras have 3-inch articulating LCD screens with a resolution of 1440k dots for the Sony a9 and 1230k dots for the Sony a7II.
The LCD screens of these two cameras come with the WhiteMagic technology that significantly improves visibility in very bright daylight.
External Flash Hot Shoe
As earlier mentioned, none of the cameras we are comparing today comes with a built-in flash. This means that you will need to rely on the use of an external flash when shooting in low-lighting conditions.
This hot shoe is where the external flash will be mounted.
Automatic Exposure Bracketing
When shooting in tricky lighting conditions, it is most confusing to pick what exposure is best for your image. In such times, exposure bracketing becomes highly essential.
Exposure bracketing involves you shooting an image at a particular exposure, and then two (more or less) other images at adjusted exposures.
When you take a look at the three images shot, it becomes easier to determine the best shot, and then decide what you want to do with the other two.
Cameras that come with the automatic exposure bracketing (AEB) feature (like the Sony a9 and a7II), allow you to automatically set this up.
This feature on these cameras enables you to set the width of the three shots to be taken.
This works such that the first shot taken will be in the set exposure, while the second shot will be underexposed by the set number of stops. And the third shot will be overexposed by the same number of set stops.
Also, auto exposure bracketing makes it easy for you to get lovely HDR photos.
Shooting in RAW ensures that your images are stored as uncompressed files that contain nominally processed image data from the camera’s image sensor.
This means that the camera stores your images in such a way that no data is lost when you need to carry out post-processing.
On the other hand, when you shoot in JPEG, the images are stored as compressed files, and so, they lose a lot of image data.
However, JPEG images are smaller in size than RAW images. Plus, you will have to process the RAW files and convert them into suitable formats to print the images or share them online.
With cameras that allow you to shoot in RAW, you still get access to any of those image formats when the need arises.
Face Detection Autofocusing
Face detection is the function of a camera that automatically sets its focus and exposure for a shot once it detects human faces within the frame.
Both equipped with this autofocusing system, when it is time to shoot portraits or film people, the Sony a9 and a7II will come in handy.
To do away with unintended blurs when shooting images in motion, you will need a camera with a quick shutter speed. The fast shutter speed helps keep the moving subject in focus by freezing the motion.
Both cameras under review have an amazing shutter speed of 1/8000 seconds. This means that with either of the two cameras, you are sure to have beautiful motion pictures, all things being equal.
It is, however, important to point out here that blurs do not necessarily have adverse effects on your images when they are planned for.
A good example is that when capturing a car race – as in sports photography – you might need to introduce some blurs. This is so that the vehicles do not look so still as if they were parked in a garage, instead of speeding down a race track. Panning is a technique that will help you out with this.
In addition to controlling blurs, fast shutter speed is an amazing tool for correcting exposure challenges and producing awesome effects.
If you intend to shoot videos with your camera, you sure will appreciate being given high-quality audio recording options. These options are what both the Sony a9 and a7II provide with the microphone port they come fitted with.
In addition to the microphone port, these cameras also come with one headphone port each. This provides you with better video control, making both cameras worthy choices for high-quality videography.
In today’s fast-paced world, being able to upload pictures from your camera to your computer or the web is a photographer’s desire.
Fortunately, both cameras provide better connectivity as they each come with a built-in wireless connectivity support.
Smartphone Remote Control
These cameras are fitted with the remote-control feature which allows you to control your camera with your smartphone. This sure makes photography more fun and more convenient.
Near Field Communication
The near field communication (NFC) feature on a camera allows wireless connectivity with compatible devices simply by touching them together.
How Different Are They From Each Other – Sony a9 vs a7II?
Here, we will look at some distinct features of both cameras. We will also look at what differentiates them in instances where they share a common feature.
One of the first noticeable differences between these two cameras is a touch-sensitive screen. Of the two cameras, only the a9 comes with a touch-sensitive screen.
Having a camera whose screen is touch-sensitive facilitates ease of use, such as easy control of camera functions.
However, it is necessary to point out that the absence of one may not be considered as a deal-breaker if you know your way around a camera.
As a photographer, knowing the battery performance of your camera helps you keep a lot of things in perspective before going on a shoot. The average battery life of mirrorless type cameras is 362 shots per full charge.
The Sony a9 comes with a newer and larger NP-FZ100 battery pack that provides you with a good-enough 650 shots per full charge. On the other hand, the a7II comes with the older NP-FW50 battery pack that affords you a not-just-okay 350 shots per full charge.
While the a9 has a good battery life, the a7II does not impress us. It will, therefore, be profitable to invest in spare batteries, especially if you will be going on long shooting sprees. After all, you never know when you will come upon an unexpected picturesque view.
Number Of Focus Points
While the Sony a9 presents you with 693 focus points, the a7II offers just 117. This large gap will greatly affect the quality of pictures gotten from these different cameras when you compare them.
Maximum Video Resolution
With the Sony a9, you will be able to shoot 4K videos at up to 30 frames per second and 100 megabits per second with full pixel readout.
On the other hand, the a7II will only be able to produce a Full HD (1920 x 1080) recording at about 60 frames per second and 50 megabits per second.
Also, the a9 comes with Sony’s S&Q mode that enables you to set frame rates between 1 and 120 frames per second for slow or quick motion playback.
However, the a7II is much more limited to 1080p videos at 60 frames per second, with no Quick mode.
The ISO of a camera tells us, in numbers, how sensitive that camera’s sensor is to light. It tells us how much light the camera can capture when it is set to a certain number.
When shooting in conditions where there is a lot of light, the camera needs to be set to a low ISO. This is because the camera takes minimal light on a low ISO to ensure that the photos come out well, without the light hiding all the details.
In low light conditions, however, the camera is to be set to a high ISO to make up for the lack of light. You sure do not want grainy photos.
In all, the wider the ISO range, the better you can play around whatever lighting condition you find.
That said, the Sony a9 is the leader in this regard. While it has an ISO range of 100 to 51,200, the a7II has a range of 100 to 25,600. That is a 100 percent difference in their maximum values.
Animal Eye Autofocusing Tracking
In addition to the face detection autofocusing, the Sony a9 has a sophisticated feature called the Animal Eye Autofocusing.
It enables the camera to identify the eyes of an animal in the scene and focus on them. It proceeds to track the eyes around the frame and keep them sharp for the shot to be taken.
Since the eyes are already sharp, there is no need for extra depth of field, and so, you can shoot at wider apertures.
This autofocusing system is as beneficial for wildlife photography as it is for taking cute pictures of your dog at home.
Unfortunately, the a7II does not come with this feature.
Of the two cameras we are comparing today – Sony a9 vs a7II – only the Sony a9 comes with Bluetooth connectivity.
