Depth of Field for the Samsung Galaxy S25 Ultra
Samsung Galaxy S25 Ultra depth of field, computed from its exact 9.8×7.4 mm sensor, 200 MP resolution and 0.0082 mm circle of confusion — the numbers its own calculators use, not a generic preset. Matching the field of view of a 50 mm lens on full frame takes only 14 mm here, and at that matched framing an f/2.8 lens gives the same depth of field as f/9.9 on full frame.

Samsung Galaxy S25 Ultra key specs: 200 MP · 3.52× crop factor · 0.60 µm pixels · CoC 0.0082 mm (standard diagonal ÷ 1500). The depth-of-field values below assume focus at 5 m.
Sensor profile: what the Samsung Galaxy S25 Ultra sensor means for depth of field
A phone sensor is tiny, so depth of field at matched framing is enormous — real background blur comes from computational processing, not optics.
| Property | Value | What it changes |
|---|---|---|
| Sensor size | 9.8 × 7.4 mm | Phone — 8% of a full-frame sensor's area |
| Crop factor | 3.52× | a Phone sensor records 3.52× the focal length, so a 50 mm lens frames like 176 mm on full frame |
| Native resolution | 200 MP (16320 × 12240) | prints 54.4 × 40.8 in at 300 ppi from the full-resolution file — lens and noise, not pixel count, cap a real print |
| Pixel pitch | 0.60 µm | how much sensor area each pixel gets — the smaller the pitch, the sooner diffraction bites |
| Circle of confusion | 0.0082 mm | the sharpness yardstick this page's depth-of-field numbers are built on (sensor diagonal ÷ 1500) |
| Diffraction limit | ≈ f/0.9 native / ≈ f/3.6 binned | past this aperture the airy disc outgrows a pixel pair and resolution falls, even though depth of field keeps growing |
Framing on the Samsung Galaxy S25 Ultra: focal length vs angle of view
Because this is a 3.52× sensor, focal lengths land differently than on full frame. Horizontal angle of view below is computed from the sensor's exact 9.8 mm width.
| Focal length | Horizontal angle of view | 35 mm equivalent | Full-frame angle for that equivalent |
|---|---|---|---|
| 16 mm | 34.1° | 56 mm | 96.7° |
| 24 mm | 23.1° | 85 mm | 73.7° |
| 35 mm | 15.9° | 123 mm | 54.4° |
| 50 mm | 11.2° | 176 mm | 39.6° |
| 85 mm | 6.6° | 299 mm | 23.9° |
How the Samsung Galaxy S25 Ultra compares to other Phone bodies
| Body | Sensor area | Resolution | Pixel pitch | Diffraction limit |
|---|---|---|---|---|
| Samsung Galaxy S25 Ultra | 73 mm² | 200 MP | 0.60 µm | ≈ f/0.9 |
| Google Pixel 9 Pro | 73 mm² | 50 MP | 1.21 µm | ≈ f/1.8 |
| iPhone 15 Pro Max | 72 mm² | 49 MP | 1.22 µm | ≈ f/1.8 |
| iPhone 16 Pro | 72 mm² | 49 MP | 1.22 µm | ≈ f/1.8 |
All values computed from the same sensor database the calculators use. Datasheet dimensions vary by a tenth of a millimetre between sources; the relative ordering here is what matters.

How to use this page
Find your lens and aperture, read the near–far range, and compose inside it — or open the interactive calculator to drag the focus distance live. On the Samsung Galaxy S25 Ultra the practical ceiling is about f/3.6: stopping down past that deepens the sharp zone but starts costing detail to diffraction, so lean on the hyperfocal column instead of the smallest aperture on the dial. For the formula and the circle-of-confusion convention behind these numbers, see the circle of confusion guide.

Frequently asked questions
What is the diffraction limit of the Samsung Galaxy S25 Ultra?
About f/3.6. At a 2.40 µm effective pixel pitch there comes a point where the airy disc from an ever-smaller aperture covers more than a pixel can resolve, so sharpness stops improving. That is the number to stop at, not f/16 or f/22.
What is the circle of confusion for the Samsung Galaxy S25 Ultra?
0.008 mm — the standard sensor diagonal ÷ 1500 convention, applied to the Samsung Galaxy S25 Ultra's exact sensor.
What is the hyperfocal distance for a 50 mm lens on the Samsung Galaxy S25 Ultra?
About 38.2 m at f/8 — focus there and everything from 19.1 m to infinity is acceptably sharp.
Does the Samsung Galaxy S25 Ultra have a crop factor?
3.52× — a 50 mm lens frames like a 176 mm lens on full frame. See the crop factor guide.
