  • Nubia Z80 Ultra: Specs and Sample Photos of 35mm, 18mm, 70mm Camera

    Key Takeaways

    1. The Nubia Z80 Ultra will be officially revealed on October 22, featuring a design similar to the Nubia Z70S Ultra.
    2. The smartphone includes a dedicated shutter button and an under-display camera, eliminating notches and punch-holes.
    3. The camera setup features a 35 mm main camera, a telephoto lens with a brighter f/2.4 aperture, and a new ultra-wide-angle camera with an 18 mm f/1.8 lens and a larger sensor.
    4. Initial sample photos emphasize natural colors and high contrast, though some images may appear slightly blurry and colors muted.
    5. The Nubia Z80 Ultra offers a 50x zoom capability, relying on a 12x digital zoom, which may impact image quality, with sample photos showing a maximum of 2x digital zoom.

    The Nubia Z80 Ultra is set to be officially revealed on October 22. Over the past weekend, Nubia shared several images that highlight the smartphone’s design intricacies. The overall appearance is quite similar to the Nubia Z70S Ultra.

    Design and Build

    Nubia has made minor tweaks to the camera module, while the device maintains a gently rounded frame. It features a dedicated shutter button and a display that incorporates an under-display camera, removing the need for notches or punch-holes. New teaser images confirm that the Z80 Ultra will come with three cameras:

    The main camera is the same 35 mm f/1.7 with a 1/1.3-inch OV990 sensor found in the Nubia Z70S Ultra. The telephoto lens continues to have a 70 mm focal length, but it now has a brighter aperture of f/2.4. Details regarding the sensor for this camera are still awaited. The most notable improvement is with the ultra-wide-angle camera, which sees Nubia replacing the 13 mm f/2.0 camera and its 1/2.88-inch sensor with an 18 mm f/1.8 camera and a larger 1/1.55-inch sensor.

    Camera Performance

    The initial sample photos taken with the Nubia Z80 Ultra’s 35 mm main camera aim to highlight the camera’s “natural perspective.” Nubia adopts a subtle approach to image processing, prioritizing natural colors over oversaturation and maintaining a relatively high contrast ratio. While some sample images seem slightly blurry, it’s important for viewers not to jump to conclusions about the low resolution of the images shared.

    Though the ultra-wide-angle camera features a significantly larger sensor, its 18 mm focal length does not provide as expansive a field of view compared to its predecessor. The sample images are not particularly revealing, as they were taken in relatively easy conditions. The skin tones in the model vary across the pictures, suggesting a moderately accurate white balance, but the photos also exhibit muted colors and a natural contrast.

    Zoom Capabilities

    As per the labeling on the camera module, the Nubia Z80 Ultra offers a 50x zoom, which requires Nubia to utilize a 12x digital zoom—likely affecting image quality. In the sample photos, Nubia restricts itself to a maximum of 2x digital zoom, demonstrating an even greater contrast ratio compared to the ultra-wide-angle and main camera.

  • Capture Stunning Portraits with Vivo X200 Ultra Smartphone Camera

    Capture Stunning Portraits with Vivo X200 Ultra Smartphone Camera

    Key Takeaways

    1. The Vivo X200 Ultra features a unique camera setup, making it difficult to identify a single “main camera” due to its well-balanced sensor sizes.
    2. It utilizes dual chips for image processing: the Vivo V3+ for post-processing and the Vivo VS1 for initial image data processing, enhancing portrait photography.
    3. The smartphone’s 35mm lens with a 1/1.28-inch sensor provides optical stabilization and excels in capturing natural-looking portraits with less distortion.
    4. Compared to rivals, the Vivo X200 Ultra offers superior portrait framing and a more attractive bokeh effect, especially in challenging lighting conditions.
    5. Users can benefit from a telephoto lens with a 3.7x zoom capability, providing versatility beyond the primary lens for various photography needs.

    The Vivo X200 Ultra stands out as one of the top smartphones of this year. Readers can discover all the specifics in our comprehensive Notebookcheck review. With its well-balanced sensor sizes, pinning down a definitive “main camera” for this flagship device from the Chinese brand proves challenging.

    Image Processing Power

    For several years, Vivo has relied on its in-house technology for the Image Signal Processor (ISP). Unlike its counterpart, the Vivo X200 Pro, which solely utilizes an ISP, the Ultra version incorporates both the Vivo V3+ chip and the Vivo VS1 chip. The V3+ chip focuses on enhancing the post-processing of images, while the VS1 chip acts as a “pre-ISP,” aimed at improving the initial processing of image data. This setup is especially advantageous for capturing portrait images.

    Photography Features

    The Vivo flagship impresses photography lovers with a 35mm lens that includes a 1/1.28-inch LYT-818 sensor along with optical stabilization. When compared to flagship rivals like the Apple iPhone 16 Pro or the Oppo Find X8 Ultra, this focal length is quite distinct.

    The distinction between the 35mm lens of the Vivo X200 Ultra and a 23mm lens, such as that found in the Galaxy S25 Ultra, lies primarily in the angle of view. Additionally, variations in focal lengths can influence distortion levels. The Vivo flagship excels in portrait photography, as it tends to result in less facial distortion compared to the broader angles found in competing smartphones. The 35mm lens on the Vivo X200 Ultra also provides a more pleasing and natural visual experience.

    Performance Comparison

    Photographs taken with the Vivo X200 Ultra versus the Galaxy S25 Ultra highlight that the former not only achieves a more natural portrait framing but also creates a more attractive bokeh effect. This is particularly beneficial when dealing with challenging subjects like our kitten, as portrait mode with artificial background blur often struggles to meet expectations.

    If the 35mm lens sometimes presents a slightly wider angle than conventional 85mm portrait lenses, users can also take advantage of the telephoto lens on the Vivo X200 Ultra, which offers a useful 3.7x zoom capability.
