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.

5D Mark II sensor is approx. 1.7x bigger than DCS620 sensor.
Note: You are comparing sensors of very different generations.
There is a gap of 9 years between Kodak DCS620 (1999) and Canon 5D Mark II (2008).
Nine years is a lot of time in terms
of technology, meaning newer sensors are overall much more
efficient than the older ones.
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.
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.
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.

Diagonal
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
| Diagonal = √ | w² + h² |
Kodak DCS620 diagonal
w = 27.65 mm
h = 18.43 mm
h = 18.43 mm
| Diagonal = √ | 27.65² + 18.43² | = 33.23 mm |
Canon 5D Mark II diagonal
w = 36.00 mm
h = 24.00 mm
h = 24.00 mm
| Diagonal = √ | 36.00² + 24.00² | = 43.27 mm |
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
DCS620 sensor area
Width = 27.65 mm
Height = 18.43 mm
Surface area = 27.65 × 18.43 = 509.59 mm²
Height = 18.43 mm
Surface area = 27.65 × 18.43 = 509.59 mm²
5D Mark II sensor area
Width = 36.00 mm
Height = 24.00 mm
Surface area = 36.00 × 24.00 = 864.00 mm²
Height = 24.00 mm
Surface area = 36.00 × 24.00 = 864.00 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 |
DCS620 pixel pitch
Sensor width = 27.65 mm
Sensor resolution width = 1733 pixels
Sensor resolution width = 1733 pixels
| Pixel pitch = | 27.65 | × 1000 | = 15.95 µm |
| 1733 |
5D Mark II pixel pitch
Sensor width = 36.00 mm
Sensor resolution width = 5613 pixels
Sensor resolution width = 5613 pixels
| Pixel pitch = | 36.00 | × 1000 | = 6.41 µm |
| 5613 |
Pixel area
The area of one pixel can be calculated by simply squaring the pixel pitch:
You could also divide sensor surface area with effective megapixels:
Pixel area = pixel pitch²
You could also divide sensor surface area with effective megapixels:
| Pixel area = | sensor surface area in mm² |
| effective megapixels |
DCS620 pixel area
Pixel pitch = 15.95 µm
Pixel area = 15.95² = 254.4 µm²
Pixel area = 15.95² = 254.4 µm²
5D Mark II pixel area
Pixel pitch = 6.41 µm
Pixel area = 6.41² = 41.09 µm²
Pixel area = 6.41² = 41.09 µm²
Pixel density
Pixel density can be calculated with the following formula:
One could also use this 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 |
DCS620 pixel density
Sensor resolution width = 1733 pixels
Sensor width = 2.765 cm
Pixel density = (1733 / 2.765)² / 1000000 = 0.39 MP/cm²
Sensor width = 2.765 cm
Pixel density = (1733 / 2.765)² / 1000000 = 0.39 MP/cm²
5D Mark II pixel density
Sensor resolution width = 5613 pixels
Sensor width = 3.6 cm
Pixel density = (5613 / 3.6)² / 1000000 = 2.43 MP/cm²
Sensor width = 3.6 cm
Pixel density = (5613 / 3.6)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:
3. To get sensor resolution we then multiply X with the corresponding ratio:
Resolution horizontal: X × r
Resolution vertical: X

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 → |
|
Resolution horizontal: X × r
Resolution vertical: X
DCS620 sensor resolution
Sensor width = 27.65 mm
Sensor height = 18.43 mm
Effective megapixels = 2.00
Resolution horizontal: X × r = 1155 × 1.5 = 1733
Resolution vertical: X = 1155
Sensor resolution = 1733 x 1155
Sensor height = 18.43 mm
Effective megapixels = 2.00
| r = 27.65/18.43 = 1.5 |
|
Resolution vertical: X = 1155
Sensor resolution = 1733 x 1155
5D Mark II sensor resolution
Sensor width = 36.00 mm
Sensor height = 24.00 mm
Effective megapixels = 21.00
Resolution horizontal: X × r = 3742 × 1.5 = 5613
Resolution vertical: X = 3742
Sensor resolution = 5613 x 3742
Sensor height = 24.00 mm
Effective megapixels = 21.00
| r = 36.00/24.00 = 1.5 |
|
Resolution vertical: X = 3742
Sensor resolution = 5613 x 3742
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 |

DCS620 crop factor
Sensor diagonal in mm = 33.23 mm
| Crop factor = | 43.27 | = 1.3 |
| 33.23 |
5D Mark II crop factor
Sensor diagonal in mm = 43.27 mm
| Crop factor = | 43.27 | = 1 |
| 43.27 |

Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture
with crop factor (a.k.a. focal length multiplier).
DCS620 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
Kodak DCS620, take the aperture of the lens
you're using and multiply it with crop factor.
