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

2 µm

7.8 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: 5.8 µm (290%)

Pixel pitch of DP1 is approx. 290% higher than pixel pitch of F200EXR.

Pixel area

4 µm²

60.84 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: 56.84 µm² (1421%)

A pixel on Sigma DP1 sensor is approx. 1421% bigger than a pixel on Fujifilm F200EXR.

Pixel density

24.94 MP/cm²

1.65 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: 23.29 µm (1412%)

Fujifilm F200EXR has approx. 1412% higher pixel density than Sigma DP1.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:

Diagonal = √

w² + h²

where w = sensor width and h = sensor height

Fujifilm F200EXR diagonal

The diagonal of F200EXR sensor is not 1/1.6 or 0.63" (15.9 mm) as you might expect, but approximately two thirds of that value - 10 mm. If you want to know why, see sensor sizes.

w = 8.00 mm
h = 6.00 mm

Diagonal = √

8.00² + 6.00²

= 10.00 mm

Sigma DP1 diagonal

w = 20.70 mm
h = 13.80 mm

Diagonal = √

20.70² + 13.80²

= 24.88 mm

Surface area

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

F200EXR sensor area

Width = 8.00 mm
Height = 6.00 mm

Surface area = 8.00 × 6.00 = 48.00 mm²

DP1 sensor area

Width = 20.70 mm
Height = 13.80 mm

Surface area = 20.70 × 13.80 = 285.66 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

F200EXR pixel pitch

Sensor width = 8.00 mm
Sensor resolution width = 3995 pixels

Pixel pitch =	8.00	× 1000	= 2 µm
	3995

DP1 pixel pitch

Sensor width = 20.70 mm
Sensor resolution width = 2655 pixels

Pixel pitch =	20.70	× 1000	= 7.8 µm
	2655

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

F200EXR pixel area

Pixel pitch = 2 µm

Pixel area = 2² = 4 µm²

DP1 pixel area

Pixel pitch = 7.8 µm

Pixel area = 7.8² = 60.84 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

F200EXR pixel density

Sensor resolution width = 3995 pixels
Sensor width = 0.8 cm

Pixel density = (3995 / 0.8)² / 1000000 = 24.94 MP/cm²

DP1 pixel density

Sensor resolution width = 2655 pixels
Sensor width = 2.07 cm

Pixel density = (2655 / 2.07)² / 1000000 = 1.65 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

F200EXR sensor resolution

Sensor width = 8.00 mm
Sensor height = 6.00 mm
Effective megapixels = 12.00

r = 8.00/6.00 = 1.33

X = √	12.00 × 1000000	= 3004
	1.33

Resolution horizontal: X × r = 3004 × 1.33 = 3995
Resolution vertical: X = 3004

Sensor resolution = 3995 x 3004

DP1 sensor resolution

Sensor width = 20.70 mm
Sensor height = 13.80 mm
Effective megapixels = 4.70

r = 20.70/13.80 = 1.5

X = √	4.70 × 1000000	= 1770
	1.5

Resolution horizontal: X × r = 1770 × 1.5 = 2655
Resolution vertical: X = 1770

Sensor resolution = 2655 x 1770

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

F200EXR crop factor

Sensor diagonal in mm = 10.00 mm

Crop factor =	43.27	= 4.33
	10.00

DP1 crop factor

Sensor diagonal in mm = 24.88 mm

Crop factor =	43.27	= 1.74
	24.88

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).

F200EXR equivalent aperture

Crop factor = 4.33
Aperture = f3.3

35-mm equivalent aperture = (f3.3) × 4.33 = f14.3

DP1 equivalent aperture

Aperture is a lens characteristic, so it's calculated only for fixed lens cameras. If you want to know the equivalent aperture for Sigma DP1, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Sigma DP1 is 1.74
