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
5.51 µm
6.05 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: 0.54 µm (10%)
Pixel pitch of D80 is approx. 10% higher than pixel pitch of D300s.
Pixel area
30.36 µm²
36.6 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.

Diagonal

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

Nikon D300s diagonal

w = 23.60 mm
h = 15.80 mm
Diagonal =  23.60² + 15.80²   = 28.40 mm

Nikon D80 diagonal

w = 23.60 mm
h = 15.80 mm
Diagonal =  23.60² + 15.80²   = 28.40 mm


Surface area

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

D300s sensor area

Width = 23.60 mm
Height = 15.80 mm

Surface area = 23.60 × 15.80 = 372.88 mm²

D80 sensor area

Width = 23.60 mm
Height = 15.80 mm

Surface area = 23.60 × 15.80 = 372.88 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

D300s pixel pitch

Sensor width = 23.60 mm
Sensor resolution width = 4281 pixels
Pixel pitch =   23.60  × 1000  = 5.51 µm
4281

D80 pixel pitch

Sensor width = 23.60 mm
Sensor resolution width = 3898 pixels
Pixel pitch =   23.60  × 1000  = 6.05 µm
3898


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

D300s pixel area

Pixel pitch = 5.51 µm

Pixel area = 5.51² = 30.36 µm²

D80 pixel area

Pixel pitch = 6.05 µm

Pixel area = 6.05² = 36.6 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

D300s pixel density

Sensor resolution width = 4281 pixels
Sensor width = 2.36 cm

Pixel density = (4281 / 2.36)² / 1000000 = 3.29 MP/cm²

D80 pixel density

Sensor resolution width = 3898 pixels
Sensor width = 2.36 cm

Pixel density = (3898 / 2.36)² / 1000000 = 2.73 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

D300s sensor resolution

Sensor width = 23.60 mm
Sensor height = 15.80 mm
Effective megapixels = 12.30
r = 23.60/15.80 = 1.49
X =  12.30 × 1000000  = 2873
1.49
Resolution horizontal: X × r = 2873 × 1.49 = 4281
Resolution vertical: X = 2873

Sensor resolution = 4281 x 2873

D80 sensor resolution

Sensor width = 23.60 mm
Sensor height = 15.80 mm
Effective megapixels = 10.20
r = 23.60/15.80 = 1.49
X =  10.20 × 1000000  = 2616
1.49
Resolution horizontal: X × r = 2616 × 1.49 = 3898
Resolution vertical: X = 2616

Sensor resolution = 3898 x 2616


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


D300s crop factor

Sensor diagonal in mm = 28.40 mm
Crop factor =   43.27  = 1.52
28.40

D80 crop factor

Sensor diagonal in mm = 28.40 mm
Crop factor =   43.27  = 1.52
28.40

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).

D300s 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 Nikon D300s, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Nikon D300s is 1.52

D80 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 Nikon D80, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Nikon D80 is 1.52
