Flagship Smartphones with Continuous Zoom Cameras Like Sony Xperia 1 VII

Key Takeaways

1. The Sony Xperia 1 VII features a 12-megapixel telephoto camera with a real zoom lens, allowing for 3.5x to 7.1x zoom without image quality loss.
2. Continuous zoom telephoto cameras may become standard in future flagship smartphones, with Samsung reportedly developing a model for Chinese brands.
3. Current examples of continuous zoom technology exist in compact cameras, like the Sony RX100 VII.
4. Challenges for continuous zoom lenses include the need for more space, often requiring smaller sensors to fit into compact designs.
5. The telephoto camera on the Xperia 1 VII uses a small 1/3.5-inch sensor, while competitors like the Xiaomi 15 Ultra use larger sensors for better optical zoom performance.

One of the standout features of the Sony Xperia 1 VII is its 12-megapixel telephoto camera, which includes a real zoom lens. This allows for a continuous adjustment of the 35mm-equivalent focal length ranging from 85mm to 170mm, providing 3.5x to 7.1x zoom without degrading the image quality, unlike digital zoom.

Future of Telephoto Cameras

Zoom lenses like this are already present in compact cameras, for instance, the Sony RX100 VII, which is priced at $1,698 on Amazon. There are indications that in the future, continuous zoom telephoto cameras might become a norm in flagship devices from various brands. According to reports from The Elec, Samsung is working on developing such a camera for Chinese smartphone makers. The specifications for this upcoming telephoto camera are not yet available, and there is no information about when it might be released. The report highlights that this camera is mainly designed for Chinese flagship smartphones rather than for Samsung Galaxy S, Apple iPhones, or Google Pixel devices.

The Advancements and Challenges

Continuous zoom lenses are anticipated to be a significant advancement in smartphone camera technology. However, they come with their own set of challenges. These lenses require considerable space, which means they might need to be combined with smaller sensors to fit into compact camera setups. For example, the telephoto camera on the Sony Xperia 1 VII utilizes a small 1/3.5-inch sensor, in contrast, the Xiaomi 15 Ultra features a 200MP periscope telephoto camera that boasts a 4.3x optical zoom using a larger 1/1.4-inch sensor—about five times bigger than Sony’s sensor.
