User reviews
Design
Type
Mirrorless
The type of camera.
viewfinder
Electronic viewfinder (EVF)
The type of viewfinder that the camera has.
weather-sealed (splashproof)
✔Sony Alpha a9
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
screen resolution
1440k dots
A higher screen resolution provides a sharper image, making it easier to review your photos.
EVF resolution
Unknown. Help us by suggesting a value.
An electronic viewfinder (EVF) with a higher resolution provides a sharper image, producing a view comparable in quality with the one displayed on an optical viewfinder.
Has a built-in focus motor
✔Sony Alpha a9
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
Has a flip-out screen
✖Sony Alpha a9
Flip-out screens can be useful for tricky shots.
With 100% coverage, you can compose the image correctly when you capture the photo. With less than full coverage, you may have to crop your photos afterward to get them looking perfect.
The size of the screen (measured diagonally).
Optics
sensor size
Full frame
One of the most important aspects of a camera is the size of its sensor. A larger sensor will capture more light, which results in improved low-light performance, dynamic range, and general image quality.
lens mount
Sony E
focus points
693
The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
megapixels (main camera)
24.2MP
The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
maximum ISO
Unknown. Help us by suggesting a value.
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
maximum expanded ISO
204800ISO
Expanded ISO allows you to go beyond the native ISO. It does this by digitally enhancing the image output. The resulting image will have less quality than when staying within the native ISO range, but it can be useful in certain situations.
has sensor shift stabilization
✔Sony Alpha a9
With sensor shift, the image sensor (rather than the lens) moves to counterbalance any vibration of the camera. This means the image will be stabilised regardless of what lens is being used.
Fast continuous shooting is useful for catching action shots.
has AF tracking
✔Sony Alpha a9
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
Videography
video recording (main camera)
2160 x 30fps
The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
Has phase-detection autofocus for videos
✔Sony Alpha a9
A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
has continuous autofocus when recording movies
✔Sony Alpha a9
When recording movies they stay focussed and sharp.
has a microphone input
✔Sony Alpha a9
A microphone port allows connecting external high-end or specialized microphones.
has a socket for a 3.5 mm audio jack
✔Sony Alpha a9
With a standard mini jack socket, you can use the device with most headphones.
has a stereo microphone
✔Sony Alpha a9
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
Has timelapse function
✔Sony Alpha a9
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
movie bitrate
100Mbps
The higher the movie recording bitrate the better the movie quality with more and crispier details and less compression artifacts.
More microphones result in better sound quality and enable the device to filter out background noise.
Battery
Battery life (CIPA)
650shots
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
has a removable battery
✔Sony Alpha a9
The battery is removable and can be replaced by the user if broken.
has a rechargeable battery
✔Sony Alpha a9
The battery can be recharged and used over again.
has a battery level indicator
✔Sony Alpha a9
An indicator shows you when the device has low battery.
battery power
2280mAh
Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.
Features
supports Wi-Fi
✔Sony Alpha a9
The device can connect to Wi-Fi.
Has Bluetooth
✔Sony Alpha a9
Bluetooth is a wireless technology that allows you to easily transfer data between different devices, such as smartphones, tablets and computers.
Has dual card slots
✔Sony Alpha a9
It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
has pixel shift shot
✖Sony Alpha a9
The camera can take a series of shots, shifting the sensor slightly with each one. These can then be combined to create an extremely high-resolution image. It’s particularly useful for things like photographing artwork.
shoots raw
✔Sony Alpha a9
A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.
supports lossless compressed raw
✖Sony Alpha a9
It is capable of shooting stills in a lossless compressed raw format. This has all the advantages of shooting raw, while taking up much less storage space. The smaller file size also allows quicker read/write speeds.
Wi-Fi version
Wi-Fi 4 (802.11n)
The Wi-Fi versions supported by the device.
supports a remote smartphone
✔Sony Alpha a9
This technology allows the users to use their smartphone as a remote control for the device.
has an HDMI output
✔Sony Alpha a9
Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
