The Samsung Galaxy Note 20 Ultra features a 100x “Space Zoom” mode that combines a 5x periscope telephoto lens with digital cropping and AI enhancement. In real-world use, it produces recognizable but heavily processed photos of distant subjects, with quality that drops significantly past 30x zoom.

Formula

The calculator above works out your running pace and speed from a finish time and distance. The formulas are:

  • Pace = Time (minutes) ÷ Distance (km), giving minutes per kilometer.
  • Speed = Distance (km) ÷ (Time (minutes) ÷ 60), giving kilometers per hour.

Variables: t = finish time in minutes, d = distance in kilometers. Pace is shown as min/km; speed as km/h.

Worked Example

Using the defaults: t = 50 minutes, d = 10 km.

  1. Pace = 50 ÷ 10 = 5.00 min/km
  2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator returns a pace of 5.00 min/km and a speed of 12.00 km/h.

How Space Zoom Works

The Note 20 Ultra uses a 5x periscope lens that physically magnifies light before it hits the sensor. Beyond 5x, the phone crops into the sensor and uses AI to fill in details. At 100x, it’s mostly digital zoom with heavy noise reduction and sharpening. The result is a photo that looks like a painting or watercolor at full resolution, but it can still capture craters on the Moon or a distant sign.

Real-World Quality at 100x

At 100x, the viewfinder is shaky, and even a slight hand movement moves the frame dramatically. The phone’s stabilization helps but doesn’t eliminate the shake. Photos taken at 100x are usable for identification (e.g., reading a street sign) but not for professional photography. The AI often over-smooths textures, making leaves, hair, and fabric look plastic.

Common Problems and Fixes

  • Shaky image: Use a tripod or rest the phone on a stable surface. The camera’s zoom lock feature helps after you tap the screen.
  • Blurry results: Ensure you’re in good light. In low light, the sensor can’t gather enough detail, so the AI invents textures.
  • Zoom not engaging: Check that you’re not in Pro mode (which limits zoom) and that the camera app is updated.

Comparing to Other Zoom Phones

The Note 20 Ultra’s 100x is similar to the S21 Ultra and S22 Ultra (both also 100x). The Pixel 7 Pro and iPhone 15 Pro Max max out at 30x or 25x, respectively. In practice, the Note 20’s 30x shots are often sharper than its 100x shots, because 30x uses less digital cropping. A dedicated camera with a 600mm lens will always beat a phone at 100x, but the phone is far more portable.

Tips for Getting Better 100x Shots

  1. Use a tripod or hold the phone against a solid object.
  2. Tap the subject to lock focus and exposure.
  3. Wait for the image to stabilize before pressing the shutter.
  4. Take multiple shots and pick the sharpest one.
  5. Shoot in good daylight; avoid zooming in low light.

Cost and Alternatives

The Note 20 Ultra was a premium phone at launch (around $1,300). Today, you can buy it used for much less. Alternatives with strong zoom include the S21 Ultra (used), S22 Ultra, and the Pixel 7 Pro (30x). If you need 100x, only Samsung’s Ultra models offer it. A budget alternative is the Galaxy S20 Ultra, which also has 100x but with older processing.

Safety and Accuracy Notes

When using zoom to photograph the Moon or the Sun, never point the phone at the sun without a proper solar filter—it can damage the sensor and your eyes. For legal or forensic zoom use (e.g., reading a license plate), remember that 100x images may not be admissible as evidence due to AI processing. Always verify critical details in person.

Frequently Asked Questions

Is 100x zoom actually useful?

Yes, for identifying distant objects like a sign, a bird, or the Moon. It’s not useful for portraits or action shots because the field of view is tiny and the image quality is soft.

Why do my 100x photos look like paintings?

The AI applies noise reduction and sharpening to hide the lack of detail. This creates a smooth, watercolor-like effect, especially on textures like leaves or fur.

Can I use 100x zoom in video?

Yes, but the video is extremely shaky and low-resolution. It’s better to use a tripod and keep the zoom below 30x for usable footage.

Does the Note 20 Ultra have a 100x zoom on the front camera?

No, the front camera is fixed-focus with no optical zoom. The 100x zoom is only on the rear periscope camera.

How does 100x zoom compare to a telescope?

A 100x phone zoom is roughly equivalent to a 20-30x spotting scope in terms of detail. A good telescope will show more detail, but the phone is easier to carry and share results instantly.
