Sensor size comparison

Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.

Bigger sensors are more effective because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.

Pixel pitch

1.31 µm

1.32 µm

Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next. It tells you how close the pixels are to each other.

The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range.

Difference: 0.01 µm (0.8%)

Pixel pitch of XP120 is approx. 0.8% higher than pixel pitch of FT30.

Pixel area

1.72 µm²

1.74 µm²

Pixel or photosite area affects how much light per pixel can be gathered. The larger it is the more light can be collected by a single pixel.

Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions (more detail) for a given sensor size.

Relative pixel sizes:

Pixel area difference: 0.02 µm² (1%)

A pixel on Fujifilm XP120 sensor is approx. 1% bigger than a pixel on Panasonic FT30.

Pixel density

57.92 MP/cm²

57.5 MP/cm²

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor.

Higher pixel density means smaller pixels and lower pixel density means larger pixels.

Difference: 0.42 µm (0.7%)

Panasonic FT30 has approx. 0.7% higher pixel density than Fujifilm XP120.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:

Diagonal = √

w² + h²

where w = sensor width and h = sensor height

Panasonic FT30 diagonal

The diagonal of FT30 sensor is not 1/2.33 or 0.43" (10.9 mm) as you might expect, but approximately two thirds of that value - 7.6 mm. If you want to know why, see sensor sizes.

w = 6.08 mm
h = 4.56 mm

Diagonal = √

6.08² + 4.56²

= 7.60 mm

Fujifilm XP120 diagonal

The diagonal of XP120 sensor is not 1/2.3 or 0.43" (11 mm) as you might expect, but approximately two thirds of that value - 7.7 mm. If you want to know why, see sensor sizes.

w = 6.16 mm
h = 4.62 mm

Diagonal = √

6.16² + 4.62²

= 7.70 mm

Surface area

Surface area is calculated by multiplying the width and the height of a sensor.

FT30 sensor area

Width = 6.08 mm
Height = 4.56 mm

Surface area = 6.08 × 4.56 = 27.72 mm²

XP120 sensor area

Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 mm²

Pixel pitch

Pixel pitch is the distance from the center of one pixel to the center of the next measured in micrometers (µm). It can be calculated with the following formula:

Pixel pitch =	sensor width in mm	× 1000
	sensor resolution width in pixels

FT30 pixel pitch

Sensor width = 6.08 mm
Sensor resolution width = 4627 pixels

Pixel pitch =	6.08	× 1000	= 1.31 µm
	4627

XP120 pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 4671 pixels

Pixel pitch =	6.16	× 1000	= 1.32 µm
	4671

Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:

Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:

Pixel area =	sensor surface area in mm²
	effective megapixels

FT30 pixel area

Pixel pitch = 1.31 µm

Pixel area = 1.31² = 1.72 µm²

XP120 pixel area

Pixel pitch = 1.32 µm

Pixel area = 1.32² = 1.74 µm²

Pixel density

Pixel density can be calculated with the following formula:

Pixel density = (	sensor resolution width in pixels	)² / 1000000
	sensor width in cm

One could also use this formula:

Pixel density =	effective megapixels × 1000000	/ 10000
	sensor surface area in mm²

FT30 pixel density

Sensor resolution width = 4627 pixels
Sensor width = 0.608 cm

Pixel density = (4627 / 0.608)² / 1000000 = 57.92 MP/cm²

XP120 pixel density

Sensor resolution width = 4671 pixels
Sensor width = 0.616 cm

Pixel density = (4671 / 0.616)² / 1000000 = 57.5 MP/cm²

Sensor resolution

Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages.

1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always.

2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:

(X × r) × X = effective megapixels × 1000000 →

X = √	effective megapixels × 1000000
	r

3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

FT30 sensor resolution

Sensor width = 6.08 mm
Sensor height = 4.56 mm
Effective megapixels = 16.10

r = 6.08/4.56 = 1.33

X = √	16.10 × 1000000	= 3479
	1.33

Resolution horizontal: X × r = 3479 × 1.33 = 4627
Resolution vertical: X = 3479

Sensor resolution = 4627 x 3479

XP120 sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 16.40

r = 6.16/4.62 = 1.33

X = √	16.40 × 1000000	= 3512
	1.33

Resolution horizontal: X × r = 3512 × 1.33 = 4671
Resolution vertical: X = 3512

Sensor resolution = 4671 x 3512

Crop factor

Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.

Crop factor =	43.27 mm
	sensor diagonal in mm

FT30 crop factor

Sensor diagonal in mm = 7.60 mm

Crop factor =	43.27	= 5.69
	7.60

XP120 crop factor

Sensor diagonal in mm = 7.70 mm

Crop factor =	43.27	= 5.62
	7.70

35 mm equivalent aperture

Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture with crop factor (a.k.a. focal length multiplier).

FT30 equivalent aperture

Crop factor = 5.69
Aperture = f3.9 - f5.7

35-mm equivalent aperture = (f3.9 - f5.7) × 5.69 = f22.2 - f32.4

XP120 equivalent aperture

Crop factor = 5.62
Aperture = f3.9 - f4.9

35-mm equivalent aperture = (f3.9 - f4.9) × 5.62 = f21.9 - f27.5
