Design
1.Has a flip-out screen
Sony Alpha a7 III
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Sony Alpha a7 III
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.Has a built-in focus motor
Sony Alpha a7 III
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.
4.weight
650g
We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
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.
6.has an optical viewfinder
Sony Alpha a7 III
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens will capture. OVFs have no time lag and require no power - as opposed to electronic viewfinders, which can drain battery life. OVFs are also better in low light situations.
Optics
1.sensor size
35.8 x 23.8mm
The larger the sensor the more light the sensor captures yielding in better image quality.
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.
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.
4.maximum light sensitivity
204800 ISO
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.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Sony Alpha a7 III
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
1.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.
2.Has phase-detection autofocus for videos
Sony Alpha a7 III
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.
3.has continuous autofocus when recording movies
Sony Alpha a7 III
When recording movies they stay focussed and sharp.
4.Has timelapse function
Sony Alpha a7 III
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.
5.has a 24p cinema mode
Sony Alpha a7 III
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.
6.supports slow-motion video recording
Sony Alpha a7 III
Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Depending on camera capabilities, frame rates for slow-motion videos vary between 60fps and 960fps.
Audio
1.has a microphone input
Sony Alpha a7 III
A microphone port allows connecting external high-end or specialized microphones.
2.has a stereo microphone
Sony Alpha a7 III
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
More microphones result in better sound quality and enable the device to filter out background noise.
4.has a socket for a 3.5 mm audio jack
Sony Alpha a7 III
With a standard mini jack socket, you can use the device with most headphones.
5.Has a zoom microphone
Sony Alpha a7 III
Zoom microphones record high-quality audio and enable you to record sound from a distance. They can be useful for recording meetings, lectures, and presentations.
6.has stereo speakers
Sony Alpha a7 III
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
Battery
1.Battery life (CIPA)
610shots
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
2.has a removable battery
Sony Alpha a7 III
The battery is removable and can be replaced by the user if broken.
3.has a rechargeable battery
Sony Alpha a7 III
The battery can be recharged and used over again.
4.has a battery level indicator
Sony Alpha a7 III
An indicator shows you when the device has low battery.
5.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.
6.has wireless charging
Sony Alpha a7 III
The manufacturer offers a branded wireless charging kit. To charge the device, you simply put it down on its charging base.
