Who it may suit

May suit collectors, casual daylight shooting, or photographers intentionally seeking an older digital-camera look.

What to check before buying used

The checks below are editorial guidance. Verify the individual camera and seller information before buying.

  • Inspect the body, screen, doors, seals, and tripod socket for impact or moisture damage.
  • Test every button, dial, flash, screen, and viewfinder.
  • Photograph a plain bright surface to check for sensor dust, dead pixels, or damage.
  • Test focus and zoom across the full range; check the lens for haze, fungus, scratches, and errors.
  • Confirm the battery holds charge and that a compatible charger is included or available.
  • Test a supported memory card and inspect the card slot for bent pins or read errors.
  • Inspect the battery compartment and contacts for leakage or corrosion.

Sensor metrics

Diagonal
6.66 mm

Sensor diagonal

√(5.33² + 4²) = 6.66 mm

Calculated from sensor width and height using the Pythagorean theorem.

Surface area
21 mm²

Sensor surface area

5.33 × 4 ≈ 21 mm²

A larger area usually offers more space to collect light, though image quality also depends on sensor generation.

Pixel pitch
3.26 µm

Pixel pitch

5.33 ÷ 1,632 × 1000 = 3.26 µm

Pixel pitch is the distance between the centers of adjacent pixels. This result assumes square pixels.

Pixel area
10.66 µm²

Pixel area

3.26² = 10.66 µm²

Theoretical pixel area is the square of pixel pitch and does not subtract physical gaps between pixels.

Pixel density
9.38 MP/cm²

Pixel density

2 MP ÷ 21 mm² ≈ 9.38 MP/cm²

Higher density means more pixels per unit area. It does not represent image quality on its own.

Actual sensor size

Rectangles use their physical proportions. Calibrate your display to approximate real-world size.

Calibrate screen size

Enter your display diagonal so sensor rectangles are shown closer to their physical size.
