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 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 |
Leica SL (Typ 601) diagonal
w = 36.00 mm
h = 24.00 mm
h = 24.00 mm
| Diagonal = √ | 36.00² + 24.00² | = 43.27 mm |
Leica M9-P diagonal
w = 35.80 mm
h = 23.90 mm
h = 23.90 mm
| Diagonal = √ | 35.80² + 23.90² | = 43.04 mm |
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
SL (Typ 601) sensor area
Width = 36.00 mm
Height = 24.00 mm
Surface area = 36.00 × 24.00 = 864.00 mm²

Surface area = 36.00 × 24.00 = 864.00 mm²
M9-P sensor area
Width = 35.80 mm
Height = 23.90 mm
Surface area = 35.80 × 23.90 = 855.62 mm²

Surface area = 35.80 × 23.90 = 855.62 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 |
SL (Typ 601) pixel pitch
Sensor width = 36.00 mm
Sensor resolution width = 6000 pixels

Sensor resolution width = 5196 pixels
Sensor resolution width = 5196 pixels
| Pixel pitch = | 35.80 | × 1000 | = 6.89 µm |
| 5196 |
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 |

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 |
SL (Typ 601) pixel density
Sensor resolution width = 6000 pixels
Sensor width = 3.6 cm
Pixel density = (6000 / 3.6)² / 1000000 = 2.78 MP/cm²
Sensor width = 3.6 cm
Pixel density = (6000 / 3.6)² / 1000000 = 2.78 MP/cm²
M9-P pixel density
Sensor resolution width = 5196 pixels
Sensor width = 3.58 cm
Pixel density = (5196 / 3.58)² / 1000000 = 2.11 MP/cm²
Sensor width = 3.58 cm
Pixel density = (5196 / 3.58)² / 1000000 = 2.11 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

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).
SL (Typ 601) 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
Leica SL (Typ 601), take the aperture of the lens
you're using and multiply it with crop factor.
Since crop factor for Leica SL (Typ 601) is 1, the equivalent aperture is aperture.
Since crop factor for Leica SL (Typ 601) is 1, the equivalent aperture is aperture.
M9-P 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
Leica M9-P, take the aperture of the lens
you're using and multiply it with crop factor.
