Today we would be looking at two mirrorless cameras– Sony a9 Vs a7SII. In this article, we would be comparing all the features of these two cameras. We would be looking at their similarities, differences, pros, and cons, and also things people are saying about it.
Mirrorless cameras have been around for quite a while. In fact, recently, many photographers have been opting for mirrorless cameras over DSLRs. The main reason for this is because of how small and compact mirrorless cameras are, compared to DSLRs.
So, the stage is set and the competition between Sony a9 Vs a7SII is going to be fierce, being that both of these cameras are made by the same company. If you do not have the time to go through the whole article, check out our comparison overview below. In the comparison overview, you’ll find all the information you need to make the right decision between Sony a9 Vs a7SII.
Comparison Overview — Sony a9 Vs a7SII
These two cameras are made by Sony, and while they do have a lot of similarities, they also have a lot of differences. For similarities, they both have wireless connection which is great for sending files to other devices, sensor-shift image stabilization to keep your images stable, RAW support, face detection focus, and so on.
For recording video, these two cameras have articulating screens that enable you frame your shots when shooting from different angles. They also come with microphone ports that allow you connect an external microphone, so you can use that to record high-quality audio.
Now, to the differences. The Sony a9 is the newer of the two cameras, so it comes with a lot of modern features that the slightly older, Sony a7SII does not come with. Features like a touchscreen, continuous shooting of 20 frames per second, Bluetooth connectivity, and support for UHS memory cards.
The Sony a9 is a great sports camera. It comes with a 24-megapixel sensor which produces really detailed images, 693 focus points for fast autofocus speeds, and 20 frames per second continuous shooting rate.
The Sony a7SII is a better studio camera. It takes great still photos and also has good video recording. One point where it slacks, though, is in autofocusing. It only has 169 focus points.
Which has the better price-value ratio: a9 or a7SII?
We would say both these cameras give about the same value for your individual prices. They are both high end cameras and considering that they’re both professional cameras, that is actually okay. The a9, however, costs quite some more than the a7SII, and it does justify that price difference by coming with a lot more features.

What Scenario Is What Camera Better For? — Sony a9 Vs a7SII
|The Sony a9 is a great all-round camera. there are a lot of scenarios where this camera comes out top-notch.||The Sony a9 is obviously bigger and better than the Sony a7SII. The Sony a7SII is great at a lot of things, but most of which the Sony a9 is just better.|
| The first of this is taking still photographs, both portraits and landscapes. Looking at its feature, this is not surprising. |
It comes with a 24-megapixel sensor that’s good enough to capture really clear pictures. With this kind of megapixel sensor, you can rest assured that your pictures will not get pixelated even if you print large sheets of them.
| However, there is one scenario where you would be better equipped shooting with the Sony a7SII, than the Sony a9. |
And that is, shooting is low-light. The Sony a9 is good in low-light, but the Sony a7SII is a beast in low-light.
| Another reason why it does so well with these kinds of pictures is dynamic range and color depth. |
These range and depth allow for great colors where the blacks come out very black, and the bright parts don’t get blurred out.
| Before we go on, here’s one tip: If you do a lot of low-light photography, get a camera with a sensor below 20 megapixels. |
We say this because the more megapixels your camera has, the more detailed your images are going to be, and in low-light that’s not what you want.
| Another scenario where this camera does well is in taking action shots. The main reason for this is this camera’s ability to capture as many as 20 frames per second. |
This is great for taking different types of action shots, including sports and wildlife activities. It can also be great for travel, imagine capturing those fun moments when the kids are running on the sands of the beach, bliss.
| With a 12-megapixel sensor, you can easily increase the ISO of your camera exponentially, without having to bother about the noise levels. |
Yes, the noise levels will increase. But because your camera doesn’t process so many megapixels, the effects of the noise is reduced.
| Still talking about taking action shots, with this camera, you don’t have to worry about auto focus, when you’re taking action shots or normal shots. |
Why? Well, the camera comes with 693 focus points that make autofocusing absolutely brilliant!
| Portability is one scenario where the Sony a7SII is not necessarily “the best” but it does slightly better than the Sony a9. |
So, if you’re going to be traveling a lot with your camera, you might want to check those few extra grams.
Before we go on with our comparison, we suggest you watch this video. It’s a compilation of different shots taken by this camera. Watch it to get a feel of the differences between shots taken by these two cameras.
Common Features — Sony a9 Vs a7SII
Here are the features common to both the Sony a9 and a7SII:
i. Electronic viewfinder
ii. Wireless connection
iii. Image stabilization
iv. Articulating screen
v. External flash hot shoe
vi. RAW support
vii. Face detection focus
viii. Microphone port
ix. Headphone port
x. Environmental sealing
xi. Auto exposure bracketing
We will now look at each of these features in detail…
You can hardly talk about mirrorless cameras without mentioning electronic viewfinders, alongside. In fact, some people prefer mirrorless cameras solely because they prefer electronic viewfinders to optical viewfinders.
Electronic viewfinders are preferred to optical viewfinders because they show you a “live view” of your image, as opposed to raw light that you see through an optical viewfinder. How does this work?
In DSLRs, light enters into the camera through the camera’s lens. When the shutter is closed the light hits a mirror. It then bounces off the mirror and is sent upwards to an optical prism. This prism then straightens the light, horizontally, and sends it to the optical viewfinder.
So, with an optical viewfinder, you see exactly what your normal eye would see.
In a mirrorless camera, it’s very different. Light enters into the camera and hits an electronic sensor. Now, instead of transferring that raw light to the viewfinder, this electronic sensor converts that light into a digital image.
This digital image is then put on a small display inside the camera. When you look into the electronic viewfinder, it is this small display you see, with the digital image.
The fact that electronic viewfinders show you a processed image is what makes them very good. What that means is that you get to see exactly how the image is going to turn out, before clicking the shutter button. This helps make sure you get the image exactly how you want it to be, without taking the shot.
Both of these cameras come with wireless connectivity. With a wireless connection, you can easily connect these devices to other devices, or to the internet. Connecting it to other devices gives you the opportunity to wirelessly transfer your files from your camera to those other devices.
Wireless transfer is a lot easier and hassle-free compared to the traditional method of transferring files. Also, it looks a lot more professional as you don’t have to be remove an SD cards, or sit at a place to being connecting wires from your camera to your laptop.
Speaking about connecting to other devices, these two cameras come with an extra wireless feature that aids that. It is called “NFC Connection”. Shortened from Near Field Communication, NFC connection allows you to connect your camera to other compatible devices, simply by putting them close to one another.
So, you only have to pair these devices once. After that, whenever you place them close to each other, they automatically connect to each other.
The Sony a9 pushes the possibilities even further with its built-in Bluetooth connectivity. Most devices made today come with built-in Bluetooth. Because of that, it’s a lot easier to transfer files using Bluetooth connectivity. Unfortunately, the Sony a7SII lacks this feature.
Apart from connecting to other devices, a wireless connection allows you to connect to the internet. This means that you can now upload your content straight off your camera if it doesn’t need much tweaking. Things like live videos, behind the scenes, and so on, will benefit from this.
You can also upload your photos and videos online for cloud storage. That not only frees up room on your SD card, it also acts as a backup incase anything happens to your SD card.
Built-in Image Stabilization
“Steady hands” is a skill that takes photographs a very long time to acquire. So what happens when you need a steady shot and you’re not in a position to use a gimbal or a tripod? With built-in image stabilization, you don’t have to worry about that.
Image stabilization refers to any technique whose aim is to keep the camera’s lens steady, even after mild camera movements. With built-in cameras, you either have an optical image stabilization, or a sensor-shift image stabilization.
Optical image stabilization shifts an element of the lens to alter the camera shake and keep the image steady. Sensor-shift does the same but shifts an element of the image sensor instead.
One major advantage with sensor-shift image stabilization is that it works with any lens you attach to your camera. Optical image stabilization does not work if you attach a lens that does not support image stabilization.
With built-in image stabilization, you can get steady videos shooting with just your hand. It’s great for vlogging or shooting through the window of a moving vehicle.
When trying to get that perfect shot, there are sometimes when you would need to shoot from certain awkward angles. It is in these scenarios that you find an articulating screen most important. With an articulating screen, you continue to have great framing and control, even when you’re shooting from those awkward angles.
This is possible because the LCD screen on these cameras are connected to the body of the cameras using a pivot. This gives the screens a fair bit of room to tilt in different directions. It’s also great for recording video as it makes it more comfortable, as you’ll be able to adjust it to fit your eye-level.
External Flash Shoe
Shooting in low-light can be tricky sometimes. This is because, while increasing your ISO might work, it also brings it’s challenging with things like “increased noise levels”.
To prevent that, you sometimes need external lighting. This is where the external flash shoe comes in. With this external flash shoe, you can conveniently connect an on-camera flash to your camera. This provides you with the extra lighting needed for those low-light shots.
When all digital cameras take a picture, that picture is originally in a RAW format. Just like the name implies, this is the raw, untouched version of that image. Although all cameras initially take pictures in this format, not all of them will allow that image to be saved in this format.
So, what the camera does is it processes the raw image, compresses it, and then converts it into a JPEG image. It then saves that JPEG image. Now, the problem with this is that during the process of compression and conversion, a lot of information on the picture is lost.
That’s why it’s worth to note that both of these cameras- Sony a9 Vs a7SII, will allow you save your pictures in RAW format. The benefit of this is that you get an untouched version of your picture which gives you limitless editing opportunities.
Face Detection Focus
A pretty underrate feature, face detection focus is one that you only think about when it’s not there, but don’t notice much when it is. With face detection focus, your camera will detect when there’s a face in the frame of the camera, and then it’ll automatically focus on it.
Think about all the time it’ll save if you take a lot of portrait shots. We know it doesn’t sound like much right now, just wait until you get a camera without the feature.
Microphone And Headphone Port
Many professionals have said that “the most important part of a video is the audio”. With that much emphasis on audio, you can see why it’s necessary to have a microphone port on your camera.
Most cameras come with built-in microphones that are pretty bad. So, more often than not, you need an external microphone to get the desired audio you want. And without a microphone port, that’ll be a hassle to achieve.
The headphone port is for connecting a headphone to your camera. This headphone not only lets you listen to stuff you’ve already recorded, it also allows you monitor your audio, as it’s being recorded.
Environmental sealing/weather sealing is done to protect the camera from damages that may be cause as a result of environmental or weather forces, like rain or wind. To achieve that, both of these cameras- Sony a9 Vs a7SII, are moisture and dust proof.
Moisture proof to prevent it from getting damaged under slight rain, dust proof to prevent the wind from destroying it by blowing dust into it. However, neither of these things are 100% safe. So, if the weather gets too wild, it’s best you take shelter. Remember that neither of these cameras is either water-resistant, or waterproof.
To get a great shot, you need to get the exposure right. But getting the exposure right is quite difficult to achieve. So, photographers created something called “the exposure bracket”.
Basically, the exposure bracket is a group of photos taken of the same scene, with the level of exposure being the only thing different in the photos. The photographer then goes through this exposure bracket later on, and chooses what picture has the best exposure.
As you can see, this process can be quite time-consuming. Having to change the exposure level each time you take a picture is quite stressful too. Which is why companies decided to create AE bracketing. Auto Exposure bracketing, in its most basic form, helps you to automatically create an exposure bracket.
All you have to do is to initially set the different levels of exposure you want. Once you’ve done that, you will need to click the shutter button only once, and the camera will automatically create the exposure bracket for you.
This not only makes the job of creating exposure brackets easier and faster, it also makes it possible for you to create HDR images. HDR images are formed by joining together all the images in an auto exposure bracket together. They are perfectly exposed.
Features Unique To Each Camera — Sony a9 Vs a7SII
Which has a touch screen: a9 or a7SII?
The LCD screen on the Sony a9 is touchscreen. With a touch screen, it’s a lot easier to navigate through this camera’s settings and menus. Also, a touch screen allows you to quickly focus on any part of the frame, simply by tapping that area on the LCD screen.
Which is better for flash photography: a9 or a7SII?
Both the a9 and a7SII are compatible with external flashes, but only the Sony a9 comes with a PC sync port which allows you to connect an off-camera flash to the camera. Off-camera flashes generally provide a lot more light and brightness than on-camera flash. It’s nice to know that you have both options with this camera.
Which has a secondary storage slot: a9 or a7SII?
While the Sony a7SII comes with a single storage slot, the Sony a9 comes with 2. With a secondary storage slot, you get double storage capacity, as well as, storage flexibility. You can use this secondary storage in two different ways; as “storage expansion” and as “backup memory”. Using it as storage expansion, your files will be saved to the primary memory first. Once that’s full, it will then begin to save on the secondary storage. If you’re recording large videos, this is very helpful.
As a backup memory, all your files are saved on both SD cards, at the same time. It’s best you use this for footage you can never get back, say a wedding, or events like that. That way, you’re sure that even if one SD card gets corrupted or lost, all your files are saved in the second SD card.
Which is compatible with UHS-II memory cards: a9 or a7SII?
You can use UHS-II memory cards with the Sony a9, while the a7SII is only compatible with UHS-I memory cards. UHS (ultra high speed) memory cards are basically SD cards that read and transfer data at ultra high speeds. On an unsupported device, these SD cards read and transfer files at normal speeds. However, their strengths show when they’re used with a device that supports them, like the a9 and a7SII.
Which can make Panoramic images: a9 or a7SII?
The Sony a7SII has the ability to create panoramic photos. It does this by stitching together multiple shots. Panoramas are a fun and creative way to shoot and it’s nice to see that this camera comes with that feature.
