GoPro has introduced the Mission 1, a new line of action cameras that positions itself as an upgrade over the popular Hero series, thanks to a 1-inch sensor — a significant step up in terms of image quality and performance. The Mission 1 comes in three versions: standard, Pro (the model tested), and Pro ILS. The 1-inch sensor is considered a major advancement in the world of compact cameras. It's small enough to fit into a compact housing but large enough to capture more light, leading to better image quality. This sensor was first used in the Insta360 One R 1-Inch Edition, launched six years ago, but GoPro is now bringing it to the action camera market with the Mission 1. The Mission 1 offers several improvements over previous models. It doubles the default depth rating to 20 meters, making it ideal for underwater use without additional equipment. It also doubles the resolution to 50 megapixels, allowing for high-resolution video up to 8K at 60 frames per second on the Pro model. The camera uses a Quad-Bayer photodiode design, which enhances detail and reduces noise, making it more suitable for both video and still photography. A new in-house processor, the GP3, allows the camera to handle more data, and it benefits from a more energy-efficient 5 nm manufacturing process. While the Mission 1's 1-inch sensor resembles those used in smartphones, which are highly optimized, GoPro has also made practical design choices. For example, it includes a removable rubber sunshade to help reduce optical distortion from its ultra-wide lens. However, this accessory can be easily misplaced. The camera also offers advanced features such as 10-bit Log recording for professional color grading, and a 32-bit floating point audio mode for high-quality sound capture, though this requires more storage space. The Mission 1 Pro is a significant leap forward in the GoPro lineup, offering features that appeal to both casual users and more experienced photographers. However, it faces competition from other brands like Insta360 and DJI, and recent news about GoPro's potential sale could affect consumer confidence. Despite these challenges, the Mission 1 represents a strong evolution in GoPro's product line, offering improved performance, versatility, and new creative possibilities for users.
