Oppo Find X9 Ultra vs. Vivo X300 Ultra: Battle of the telephoto smartphones

On the Find X9 Ultra, the primary camera has a 200-megapixel 1/1.28-inch sensor. With a low f/1.5 aperture possible, this is an incredibly versatile camera, built to take in light and work well even in difficult shooting conditions. There's also a pair of telephoto cameras. The first has a 200MP sensor and can zoom up to 3x (70mm equivalent) for portrait photos and general-purpose shots, while the showstopper is an 'ultra' telephoto, capable of 10x zoom at 50MP. It's rare, but we've seen 10x zoom in smartphones, including, briefly, Samsung's Galaxy S23 Ultra. However, they weren't paired with such high-resolution sensors. This offers more detail in shots, as well as the ability to digitally crop down to get even closer to the subject — although you won't need to nearly as often. The Find X9 Ultra also has a 50MP ultra-wide camera and a 3.2MP multispectral sensor to strengthen white balance and color accuracy.

The 10x optical zoom also opens up the possibility of 20x lossless zoom, all before we start attaching Oppo's teleconvertor lens. It also has sensor-shift stabilization to improve clarity and reduce the chances of blur. (Vivo has its own solution, which we'll get to in a minute.) The 3x telephoto camera is a convenient midpoint between the main camera and its huge sensor and the incredible range of the 10x telephoto. However, Oppo gets a little too keen on computational photography boosting here and I'd often get shots with ghostly outlines, especially of human subjects. Overly aggressive digital sharpening also made some images look unnatural. Mat Smith for Engadget Within the camera app (and arguably too many shooting modes), Oppo's collaboration with Hasselblad gives shooters a Master Mode that blissfully strips away the computational AI tricks and augmentations. This means that while you won't get that AI nip-tuck on telephoto shots, you also won't get nightmarish low-res faces or scrambled alien lettering. I broadly preferred it, though I occasionally missed the better low-light performance of the AI-boosted basic photo mode. Mat Smith for Engadget The Vivo X300 Ultra has the exact same 1/1.12-inch 200MP main camera sensor, although it has a narrow 35mm focal length, which could be argued to be more "cinematic'. Its aperture can go as low as f/1.85, losing again to its Oppo rival. The X300 Ultra ultrawide camera, however, performs head and shoulders above the Find X9 Ultra's version. Unlike most smartphone ultra-wide cameras, which I cynically view as a lazy effort by companies to add another camera to their smartphones, Vivo went to town. To start, Vivo added optical image stabilization (OIS), which is rare for this focal length. This, combined with a 50MP sensor, means images look crisper and more detailed than those from rival devices, which typically use lower-res sensors. To Oppo's credit, its ultrawide camera isn't bad. The Find X9 Ultra also has a 50MP camera sensor and a lower f/2.0 lens. However, the sensor isn't as big (the X300 Ultra's 1/1.28-inch sensor is nearly twice the physical size of the Find X9 Ultra's 1/1.95-inch sensor) and it lacks built-in OIS. There's also a lot less lens flaring on light sources with the Vivo phone, likely due to Zeiss' anti-reflective lens treatment. Mat Smith for Engadget The X300 Ultra's telephoto (another 200MP sensor) maxes out at 3.7x zoom without a teleconverter and while you can crop down from that for more 'zoom', it loses a lot of detail and adds a lot of artifacts in the process. Fortunately, for those looking to punch in further, Vivo has you covered.
