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.

Canon EOS D30 Canon EOS 30D
Surface area:
342.77 mm² vs 337.50 mm²
Difference: 5.27 mm² (2%)
D30 sensor is slightly bigger than 30D sensor (only 2% difference).
Note: You are comparing sensors of very different generations. There is a gap of 6 years between Canon D30 (2000) and Canon 30D (2006). Six years is a lot of time in terms of technology, meaning newer sensors are overall much more efficient than the older ones.
Pixel pitch
10.52 µm
6.42 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: 4.1 µm (64%)
Pixel pitch of D30 is approx. 64% higher than pixel pitch of 30D.
Pixel area
110.67 µm²
41.22 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.

Pixel area difference: 69.45 µm² (168%)
A pixel on Canon D30 sensor is approx. 168% bigger than a pixel on Canon 30D.
Pixel density
0.9 MP/cm²
2.43 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: 1.53 µm (170%)
Canon 30D has approx. 170% higher pixel density than Canon D30.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:
Diagonal = √  w² + h²
where w = sensor width and h = sensor height

Canon D30 diagonal

w = 22.70 mm
h = 15.10 mm
Diagonal = √  22.70² + 15.10²   = 27.26 mm

Canon 30D diagonal

w = 22.50 mm
h = 15.00 mm
Diagonal = √  22.50² + 15.00²   = 27.04 mm


Surface area

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

D30 sensor area

Width = 22.70 mm
Height = 15.10 mm

Surface area = 22.70 × 15.10 = 342.77 mm²

30D sensor area

Width = 22.50 mm
Height = 15.00 mm

Surface area = 22.50 × 15.00 = 337.50 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

D30 pixel pitch

Sensor width = 22.70 mm
Sensor resolution width = 2157 pixels
Pixel pitch =   22.70  × 1000  = 10.52 µm
2157

30D pixel pitch

Sensor width = 22.50 mm
Sensor resolution width = 3506 pixels
Pixel pitch =   22.50  × 1000  = 6.42 µm
3506


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

D30 pixel area

Pixel pitch = 10.52 µm

Pixel area = 10.52² = 110.67 µm²

30D pixel area

Pixel pitch = 6.42 µm

Pixel area = 6.42² = 41.22 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

D30 pixel density

Sensor resolution width = 2157 pixels
Sensor width = 2.27 cm

Pixel density = (2157 / 2.27)² / 1000000 = 0.9 MP/cm²

30D pixel density

Sensor resolution width = 3506 pixels
Sensor width = 2.25 cm

Pixel density = (3506 / 2.25)² / 1000000 = 2.43 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

D30 sensor resolution

Sensor width = 22.70 mm
Sensor height = 15.10 mm
Effective megapixels = 3.10
r = 22.70/15.10 = 1.5
X = √  3.10 × 1000000  = 1438
1.5
Resolution horizontal: X × r = 1438 × 1.5 = 2157
Resolution vertical: X = 1438

Sensor resolution = 2157 x 1438

30D sensor resolution

Sensor width = 22.50 mm
Sensor height = 15.00 mm
Effective megapixels = 8.19
r = 22.50/15.00 = 1.5
X = √  8.19 × 1000000  = 2337
1.5
Resolution horizontal: X × r = 2337 × 1.5 = 3506
Resolution vertical: X = 2337

Sensor resolution = 3506 x 2337


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


D30 crop factor

Sensor diagonal in mm = 27.26 mm
Crop factor =   43.27  = 1.59
27.26

30D crop factor

Sensor diagonal in mm = 27.04 mm
Crop factor =   43.27  = 1.6
27.04

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).

D30 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 Canon D30, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon D30 is 1.59

30D 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 Canon 30D, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Canon 30D is 1.6
