Cheap alternatives for Sony a7R IV

Design

1.weather-sealed (splashproof)
Sony a7R IV
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
2.Has a flip-out screen
Sony a7R IV
Flip-out screens can be useful for tricky shots.
3.Has a built-in focus motor
Sony a7R IV
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.viewfinder coverage

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.
5.Has a hot shoe
Sony a7R IV
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
6.has an optical viewfinder
Sony a7R IV
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.focus points

567

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.
2.sensor size

35.7 x 23.8mm

The larger the sensor the more light the sensor captures yielding in better image quality.
3.has AF tracking
Sony a7R IV
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.
4.Has phase-detection autofocus for photos
Sony a7R IV
Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.
5.maximum light sensitivity

102800 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.
6.has built-in optical image stabilization
Sony a7R IV
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

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 a7R IV
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 a7R IV
When recording movies they stay focussed and sharp.
4.Has timelapse function
Sony a7R IV
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 a7R IV
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 a7R IV
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
Sony a7R IV
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
2.has a microphone input
Sony a7R IV
A microphone port allows connecting external high-end or specialized microphones.
3.number of microphones

2

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 a7R IV
With a standard mini jack socket, you can use the device with most headphones.
5.has stereo speakers
Sony a7R IV
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
6.Has a zoom microphone
Sony a7R IV
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.

Battery

1.Battery life (CIPA)

670shots

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 a7R IV
The battery is removable and can be replaced by the user if broken.
3.has a rechargeable battery
Sony a7R IV
The battery can be recharged and used over again.
