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.

Note: You are comparing sensors of vastly different generations.
There is a gap of 19 years between Nikon 800 (1999) and
Nikon Z7 (2018).
Nineteen years is a huge amount of time,
technology wise, resulting in newer sensor being much more
efficient than the older one.
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 |
Nikon 800 diagonal
The diagonal of 800 sensor is not 1/2 or 0.5" (12.7 mm) as you might expect, but approximately two thirds of
that value - 8 mm. If you want to know why, see
sensor sizes.
w = 6.40 mm
h = 4.80 mm
w = 6.40 mm
h = 4.80 mm
| Diagonal = √ | 6.40² + 4.80² | = 8.00 mm |
Nikon Z7 diagonal
w = 35.90 mm
h = 23.90 mm
h = 23.90 mm
| Diagonal = √ | 35.90² + 23.90² | = 43.13 mm |
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
800 sensor area
Width = 6.40 mm
Height = 4.80 mm
Surface area = 6.40 × 4.80 = 30.72 mm²
Height = 4.80 mm
Surface area = 6.40 × 4.80 = 30.72 mm²
Z7 sensor area
Width = 35.90 mm
Height = 23.90 mm
Surface area = 35.90 × 23.90 = 858.01 mm²
Height = 23.90 mm
Surface area = 35.90 × 23.90 = 858.01 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 |
800 pixel pitch
Sensor width = 6.40 mm
Sensor resolution width = 1589 pixels
Sensor resolution width = 1589 pixels
| Pixel pitch = | 6.40 | × 1000 | = 4.03 µm |
| 1589 |
Z7 pixel pitch
Sensor width = 35.90 mm
Sensor resolution width = 8280 pixels
Sensor resolution width = 8280 pixels
| Pixel pitch = | 35.90 | × 1000 | = 4.34 µm |
| 8280 |
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 |
800 pixel area
Pixel pitch = 4.03 µm
Pixel area = 4.03² = 16.24 µm²
Pixel area = 4.03² = 16.24 µm²
Z7 pixel area
Pixel pitch = 4.34 µm
Pixel area = 4.34² = 18.84 µm²
Pixel area = 4.34² = 18.84 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 |
800 pixel density
Sensor resolution width = 1589 pixels
Sensor width = 0.64 cm
Pixel density = (1589 / 0.64)² / 1000000 = 6.16 MP/cm²
Sensor width = 0.64 cm
Pixel density = (1589 / 0.64)² / 1000000 = 6.16 MP/cm²
Z7 pixel density
Sensor resolution width = 8280 pixels
Sensor width = 3.59 cm
Pixel density = (8280 / 3.59)² / 1000000 = 5.32 MP/cm²
Sensor width = 3.59 cm
Pixel density = (8280 / 3.59)² / 1000000 = 5.32 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
800 sensor resolution
Sensor width = 6.40 mm
Sensor height = 4.80 mm
Effective megapixels = 1.90
Resolution horizontal: X × r = 1195 × 1.33 = 1589
Resolution vertical: X = 1195
Sensor resolution = 1589 x 1195
Sensor height = 4.80 mm
Effective megapixels = 1.90
| r = 6.40/4.80 = 1.33 |
|
Resolution vertical: X = 1195
Sensor resolution = 1589 x 1195
Z7 sensor resolution
Sensor width = 35.90 mm
Sensor height = 23.90 mm
Effective megapixels = 45.70
Resolution horizontal: X × r = 5520 × 1.5 = 8280
Resolution vertical: X = 5520
Sensor resolution = 8280 x 5520
Sensor height = 23.90 mm
Effective megapixels = 45.70
| r = 35.90/23.90 = 1.5 |
|
Resolution vertical: X = 5520
Sensor resolution = 8280 x 5520
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 |
800 crop factor
Sensor diagonal in mm = 8.00 mm
| Crop factor = | 43.27 | = 5.41 |
| 8.00 |
Z7 crop factor
Sensor diagonal in mm = 43.13 mm
| Crop factor = | 43.27 | = 1 |
| 43.13 |
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).
800 equivalent aperture
Crop factor = 5.41
Aperture = f3.5 - f4.8
35-mm equivalent aperture = (f3.5 - f4.8) × 5.41 = f18.9 - f26
Aperture = f3.5 - f4.8
35-mm equivalent aperture = (f3.5 - f4.8) × 5.41 = f18.9 - f26
Z7 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 Z7, take the aperture of the lens
you're using and multiply it with crop factor.
Since crop factor for Nikon Z7 is 1, the equivalent aperture is aperture.
Since crop factor for Nikon Z7 is 1, the equivalent aperture is aperture.
