In a photowalk comparison, the Vivo X300 Ultra repeatedly beat the Samsung Galaxy S26 Ultra for 1x clarity, portraits, and telemacro focus—while Samsung’s strengths showed up more in saturation at night and highlights on a white shirt.
When the first shots loaded after a photowalk, the surprise wasn’t just who looked better—it was how often the Samsung Galaxy S26 Ultra fell short in the spots I actually use day to day: simple 1x framing, quick tap-to-focus, and keeping details sharp instead of pushing them too hard.
The two phones—Samsung’s Galaxy S26 Ultra and Vivo’s X300 Ultra—were both pitched as “Ultra” camera flagships outside the US. where the competition from Chinese ultra phones is getting fierce. Vivo’s X300 Ultra goes after Samsung with a camera system built around three massive sensors. and the test was straightforward: take both on the same photowalk. then see what survives at the pixel level.
What’s on the spec sheet is already part of the story. The Samsung Galaxy S26 Ultra’s main camera is a 200MP unit with OIS and PDAF. using a 1/1.3″ sensor with an f/1.4 aperture and a 23mm focal length. Vivo’s main camera is also 200MP with OIS. laser autofocus. and PDAF. but it uses a 1/1.12″ sensor with an f/1.9 aperture and a 35mm focal length.
The telephoto setup is where their approaches diverge again. The Galaxy S26 Ultra’s telephoto camera is 50MP with periscope tele. OIS. and PDAF. a 1/2.52″ sensor. an f/2.9 aperture. and 5x optical zoom. Vivo’s telephoto camera is 10MP with OIS and PDAF, a 1/3.94″ sensor, f/2.4 aperture, and 3x optical zoom. On ultrawide. both list 50MP sensors—Samsung’s has PDAF with a 1/2.5″ sensor and f/1.9 aperture. while Vivo’s has OIS and PDAF with a 1/1.28″ sensor and f/2.0 aperture.
The first real moment of clarity came at 1x.
Vivo changed its focal length to 35mm. so the optical quality shows up without leaning on a 1.5x digital zoom trick—something many modern phones do. Most other modern phones, including the Galaxy S26 Ultra, use a smaller 23mm-equivalent focal length on the main sensor. If you want the Vivo framing at 35mm as the default, you can set it.
In my own shooting habits. I zoom in at 1.2x and 1.5x for day-to-day shots. and that’s why I liked using the Vivo X300 Ultra more on this photowalk. But there were times I missed having 23mm by default. Vivo still offers a workaround: you can use the ultrawide-angle lens and zoom in to shoot at 23mm.
On the test frames. the Vivo X300 Ultra delivered more depth at 1x. which the write-up credits to a bigger sensor. The Galaxy S26 Ultra, by contrast, looked like it was oversharpening. The difference showed up in the kind of casual details that don’t forgive a heavy-handed processing pass—like the purple patch with flowers in a 1x example.
When it came to comparing 35mm-equivalent optical versus digital quality, Vivo again benefited from staying optical. The Vivo 1x shot gave what was described as the “perfect frame. ” while Samsung had to move to 1.5x digital zoom to get something similar. That digital zoom produced fewer details and a noisier photo—down to the reds of a yet-to-bloom flower.
It wasn’t just sharpness. The Vivo phone added a more natural bokeh on the main-camera shot. Samsung’s 1x result also got skin tone right, but it struggled with colors in the sky and ground, looking rather gloomy.
The color story stayed tense through the simplest tap-to-shoot workflow. All photos were taken as tap-and-shoot—no manual exposure or other settings. Vivo’s 1x shots had more contrast, character, and detail, while the Galaxy S26 Ultra looked overexposed and lacked the same amount of detail.
Daylight portraits put the competition under a different light.
On the tele sensor. the Vivo X300 Ultra was described as producing a more natural bokeh. retaining a close-to-real-life look. and matching the correct color tone of the eyes—while the Galaxy S26 Ultra went for a warmer look. At sunset, the story split again. Samsung handled sunlight on the face more comfortably, even though it lacked detail in the shadows. The Galaxy S26 Ultra also gave more natural-looking sunset portraits. and the comparison note points out Samsung’s pattern: it “takes great portraits under the setting sun” and beat Vivo here.
Pixel-peepers got the more uncomfortable part of Samsung’s processing. Vivo retained more details on the beard, while Samsung oversharpened certain areas. Yet Samsung didn’t lose everywhere: it handled highlights on a white T-shirt better.
The hardest test—telemacro—was where Vivo’s advantage got sharp.
Both phones were tested on a tricky subject: a small flower that kept moving in the slightest breeze. With the Galaxy S26 Ultra, it was a struggle to keep it in focus even after tapping. Vivo’s X300 Ultra, described as focusing on it with a single tap, even captured white threads in the picture.
Even the “zoom as far as you can” moment highlighted a practical gap. The comparison included a 10x zoom macro shot on the Vivo X300 Ultra. No Galaxy S26 Ultra shot was available at 10x because it couldn’t focus at 10x digital zoom.
Ultrawide shots were closer, but the edge still went Vivo. Both phones were described as keeping colors consistent across lenses, yet Vivo offered richer details again. Still, the photographer preferred Samsung’s ultrawide shot in this case because Vivo overexposed the sky.
Night mode flipped the emphasis toward Samsung—at least on color taste. In night mode, the preference was for Samsung’s saturated colors over Vivo’s look. Vivo could increase saturation with filter adjustments—Natural was used in the test. but Textured would deliver a more dramatic look—yet Samsung produced more contrast. especially loved on a signboard.
Video recording added another reason the Vivo felt more built for creators, not just headlines. Vivo offers a film mode that mimics the look of a movie with a single tap. For people who want recipes from Fujifilm or Ricoh. you can create equivalent looks and share them among friends with a QR code. The test notes that the author hasn’t seen other phone manufacturers make those steps this simple.
After all the tap-and-shoot frames—1x, 1.5x digital comparisons, portraits, telemacro, ultrawide, and night mode—the conclusion landed where the tension started: not in specs, but in what consistently showed up in real photos.
Both the Samsung Galaxy S26 Ultra and the Vivo X300 Ultra were described as having strengths, weaknesses, and unique capabilities. But the write-up goes further than a tie. It says the Vivo X300 Ultra will better satisfy photographers. that Samsung might be enough for most people because of a friendlier user interface. and that the Vivo offers more character. easy color profile switching. and big-sensor detail.
“I’ve used all the Ultra phones launched this year and would pick the Vivo X300 Ultra for its cameras,” the piece states, ending with a confident verdict: “In my opinion, it is the best camera phone of 2026.”
