Oppo Find X8 Ultra

• Default Settings and Available Resolutions:
  • The Oppo Find X8 Ultra uses computational photography by default, combining multiple frames (stacking) on each camera to achieve higher resolution.
  • Users can export images at 12.5 MP (resized for maximum clarity), 26 MP, or 50 MP.
• Resolution Differences:
  • The 26 MP and 50 MP options offer visibly higher resolution compared to 12.5 MP, although the 12.5 MP setting is nearly perfect in terms of clarity.
  • Recommendation: It’s worth shooting at 26 MP consistently for the best balance of detail and clarity.
  • The 50 MP mode performs very well in certain scenarios but depends on how steady the phone is held and how much the subjects in the frame move. Motion can introduce artifacts.

• Night Photos:
  • All cameras produce clear images in low-light conditions.
  • However, the computational algorithms need further refinement: strange artifacts appear around moving cars and their headlights (e.g., streaks or halos).
• 3x Telephoto Camera (70 mm equivalent):
  • This camera exhibits unusual artifacts, such as halos with streaks around specular LED lights (e.g., streetlights or car headlights). These artifacts are also noticeable in night videos.
  • The other sensors do not show these issues in video mode.
• 6x Telephoto Camera (135 mm equivalent):
  • There is a slight blooming effect (a diffuse halo) around bright lights, particularly those tending toward white.
  • The effect is more pronounced at 50 MP resolution or with higher digital zoom levels.

• Comparison with Find X7 Ultra:
  • The ultrawide sensor, Samsung JN5 (1/2.75 inch), is nearly twice as small as the Sony LYT-600 (1/2 inch) used in the Find X7 Ultra.
  • Thanks to advanced computational algorithms and processing, the JN5 produces visibly better images than its larger predecessor, both in good light and low-light conditions, as well as in video mode.

• 4K Resolution:
  • 4K videos are smooth and high-quality at all focal lengths.
  • In low-light conditions (night), the camera tends to use a 2x crop from the 70 mm sensor instead of the 135 mm sensor when light levels drop significantly.
• Frame Rates:
  • All cameras support video recording at 30 fps and 60 fps.
  • 4K recording at 120 fps is available only on the 23 mm (main) and 70 mm (3x telephoto) cameras.
  • The phone also supports Full HD at 240 fps, but it’s unclear on how many cameras this is available (further testing required).

• The tonality, colors, and white balance (WB) are very good across all focal lengths.
• The larger Sony sensors (LYT-900, LYT-700, LYT-600) offer better dynamic range (DR) and more detail compared to the ultrawide camera (Samsung JN5).

• 3x Telephoto Camera (70 mm):
  • The macro function has been moved to the 70 mm sensor, allowing focusing as close as 10 cm from the lens.
  • Macro shots can be taken at 50 MP resolution, providing additional magnification through cropping if desired.
• 6x Telephoto Camera (135 mm):
  • This camera lacks macro functionality and cannot focus at close distances.

• Master Mode:
  • JPG and RAW images at 12.5 MP are single-shot captures.
  • Computational RAW and JPG at 50 MP are also available, but their performance requires further testing.
• Motion Priority:
  • The observations above apply to standard photo and video modes.
  • Algorithms may change when prioritizing motion, which requires further testing.
• General Note:
  • The analysis focuses solely on photo and video modes.

Well, you can read their review and decide for yourself if their findings are similar to mine, and if my evaluation tells anything useful or not. I had to cite the source images, case they where not mine, and it only fair IMO.

GSMarena observations:

"What we're struggling a bit more to see is any real advantage in shooting in 25MP resolution on the main camera"..."It's sort of a similar story with the switch to 50MP - things are just getting progressively softer on a pixel level, and if there's an actual extra amount of detail, it's not plain to see."

"There's one unusual flaw that you may or may not run into - if you have moving bright lights in the frame, they can get rendered weirdly in a hard to describe ghost-like way (the fifth sample below)."

My observations:

"Resolution Differences:

• The 26 MP and 50 MP options offer visibly higher resolution compared to 12.5 MP, although the 12.5 MP setting is nearly perfect in terms of clarity.
• Recommendation: It’s worth shooting at 26 MP consistently for the best balance of detail and clarity.

The 50 MP mode performs very well in certain scenarios but depends on how steady the phone is held and how much the subjects in the frame move. Motion can introduce artifacts."

I also critiqued the staking quality bright subjects in low-light such as car headlights, on all sensors. Highlighted the ugly artifacts on both street lights and car headlights on the 70mm Sony LYT 700 lens module both on photo and video mode etc.

"6x Telephoto Camera (135 mm equivalent)

• There is a slight blooming effect (a diffuse halo) around bright lights, particularly those tending toward white.
• The effect is more pronounced at 50 MP resolution or with higher digital zoom levels."

This is probably a side effect of the W light path lens structure of the 135mm LYT 600 camera module:

etc.

Oppo needs to drop sharpening on all lenses by about 30%

Its good that they slightly reduced denoise however, but the sharp going up is a no go for me, especially since you cannot control it in non master mode, and master mode HDR is weak to a point some shots are unusable, so either they improve HDR in master, or add master controls to regular mode.

RAW 3rd party looks quite good on the other hand!

Would these negative effects you are mentioning not be present in regular Raw but actually present in RAW+?

On 12,5mp modes, Oppo can reduce the sharpness by half, is you ask me!

The good news is the new 26mp (5888x4416 pixels) resolution option available on all cameras (now) on photo mode, looks very well, with just about right amount of sharpness I'd say.

I'm certain, the image quality will be improved with software updated. The X7 Ultra received image improvements for an entire year.

On the Oppo Find X8 Ultra haven't found such an option. But I'm very satisfied with the improvement of digital zoom. The 300mm digitally zoomed focal length looks quite usable now.

Seems the bokeh balls module are bokeh rectangles.

This looks like square bokeh from MC Zenitar-ME1 50 mm f1.7 Lens, rare Soviet lens with only two aperture blades that form a square opening.

If this is how the bokeh looks like then it is not a good news unless it can be changed to standard circular bokeh balls type.
