Blackmagic Design is an Australian company that manufactures professional digital cinema cameras, video editing software, and other products for filmmakers and video producers. Founded in 2001, Blackmagic has become well-known for its affordable, high-quality cameras that can produce stunning video.
Some of Blackmagic’s most popular cameras include the Pocket Cinema Camera line and the URSA series. The Pocket Cinema Cameras are compact and portable while still being able to capture RAW and ProRes footage. The URSA cameras are larger, more full-featured cinema cameras designed for professional film and video work.
Across all their cameras, Blackmagic emphasizes high dynamic range, film-like image quality, and extensive recording formats like RAW and ProRes. This has made them a favorite among independent filmmakers and videographers looking for cinema-quality footage at budget prices.
Importance of Autofocus in Filmmaking
Autofocus can be an extremely useful tool for filmmakers when used properly. The main benefits of autofocus include:
- Allows camera operators to focus quickly on moving subjects
- Helps achieve sharp focus when there is limited depth of field
- Useful for run-and-gun style documentary or event filming
- Can help speed up the filming process
However, autofocus also has limitations. Many filmmakers still prefer manual focus for full creative control and to ensure focus is exactly where they intend. But overall, having solid autofocus capabilities gives filmmakers greater flexibility when needed.
Overview of Blackmagic Pocket Cinema Cameras
The 4K Model
The original Blackmagic Pocket Cinema Camera 4K was released in 2018. It features a 4/3 sensor and can shoot 4K video up to 60 fps. The dynamic range is 13 stops and it can capture footage in RAW and ProRes formats. The ISO range is dual native 400 and 3200 ISO. Overall, it delivers outstanding cinema-quality video in a portable, affordable package.
The 6K Model
Blackmagic later released the Pocket Cinema Camera 6K in 2019. As the name suggests, it can shoot up to 6K resolution, giving more flexibility in post-production. It has a larger Super 35 sensor with 13 stops of dynamic range. The dual native ISO remains 400 and 3200. It can record RAW and ProRes video at various compressed or uncompressed settings.
The G2 and Pro Models
In 2022, Blackmagic introduced the Pocket Cinema Camera 6K G2 and Pocket Cinema Camera 6K Pro. They retain the same 6K sensor and recording capabilities. The main upgrades are an adjustable touchscreen, larger battery, and improved low-light performance. The Pro model also adds built-in ND filters and an adjustable iris control on the lens mount.
Understanding Autofocus
What is Autofocus?
Autofocus is a camera feature that automatically adjusts the lens focus, rather than the camera operator manually turning the focus ring. There are different autofocus modes, but it essentially works by using sensors and algorithms to detect what the camera is pointed at and shift the lens elements to achieve sharp focus.
How does it work?
There are two main types of autofocus systems:
- Contrast detection: The camera analyzes the image coming through the lens and detects areas of high contrast, which represent sharp focus. The focus is adjusted until the maximum contrast is achieved.
- Phase detection: Separate sensors measure the phase difference between incoming light rays. The camera then knows which direction and how much to shift the lens for proper focus.
Advanced autofocus systems combine both contrast and phase detection for fast and accurate performance.
Why is it important?
Autofocus enables camera operators to quickly focus on subjects, especially when they are moving. This allows them to concentrate more on framing and capturing the shot. It is extremely useful for run-and-gun shooting where there is little time to manually focus. It also helps achieve sharp focus in tricky conditions like low light or shallow depth of field.

Comparisons with other brands’ Autofocus systems

These use phase and contrast detection to lock focus and track moving subjects quickly. While manual focus remains essential, well-implemented autofocus gives these cameras greater versatility.
For filmmakers who rely on autofocus as an occasional tool, the lack of capability on the Blackmagic cameras must be considered. But those comfortable with manual focus may appreciate the simplicity and pure focus control of the Blackmagic approach.
