Sensor Size

This is the actual size of the M-E (Typ 240) sensor: 35.8 x 23.9 mm
The sensor surface area is 855.6 mm². There is a resolution of 24,000,000 pixels. Resolution shows the width from the center of one photosite to the center of the following.

The pixel area is 35.64 µm². Pixels give lighter capture and the more data can be recorded.

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. Leica M-E (Typ 240) has a pixel density of 2.81 MP/cm².

Diagonal

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


Leica M-E (Typ 240) diagonal:

w = 35.80 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.

Width = 35.80 mm
Height = 23.90 mm

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

Leica M-E (Typ 240) pixel pitch:

Sensor width = 35.80 mm
Sensor resolution width = 6000 pixels
Pixel pitch =   35.80  × 1000  = 5.97 µm
6000


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

Leica M-E (Typ 240) pixel area:

Pixel pitch = 5.97 µm

Pixel area = 5.97² = 35.64 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

You could also use this formula:
Pixel density =   effective megapixels × 1000000 / 10000
sensor surface area in mm²

Leica M-E (Typ 240) pixel density:

Sensor resolution width = 6000 pixels
Sensor width = 3.58 cm

Pixel density = (6000 / 3.58)² / 1000000 = 2.81 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

Leica M-E (Typ 240) sensor resolution:

Sensor width = 35.80 mm
Sensor height = 23.90 mm
Effective megapixels = 24.00
r = 35.80/23.90 = 1.5
X =  24.00 × 1000000  = 4000
1.5
Resolution horizontal: X × r = 4000 × 1.5 = 6000
Resolution vertical: X = 4000

Sensor resolution = 6000 x 4000


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


Leica M-E (Typ 240) crop factor:

Sensor diagonal = 43.04 mm
Crop factor =   43.27  = 1.01
43.04

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).

Leica M-E (Typ 240) 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 M-E (Typ 240), take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Leica M-E (Typ 240) is 1.01
