Design

1.Has a flip-out screen
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
Flip-out screens can be useful for tricky shots.
2.weather-sealed (splashproof)
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
3.Has a built-in focus motor
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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

440g

673g

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.
5.viewfinder coverage

100%

100%

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.is dustproof and water-resistant
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.

Optics

1.sensor size

35.9 x 24mm

35.6 x 23.8mm

The larger the sensor the more light the sensor captures yielding in better image quality.
2.focus points

33

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.
3.megapixels (main camera)

36.4MP

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.
4.maximum light sensitivity

819200 ISO

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.
5.continuous shooting at high resolution

4.4fps

20fps

Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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)

1080 x 30fps

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
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
When recording movies they stay focussed and sharp.
4.Has timelapse function
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
Sony Alpha a9 + Sony FE 24-70mm F2.8 GM
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. Frame rates for slow-motion videos vary between 60fps and 960fps.

Audio

1.has a stereo microphone
Pentax K-1 Mark II + Pentax D FA 28-105mm HD f/3.5-5.6 ED DC WR
