Diagonal

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

Fujifilm X-Pro3 diagonal

w = 23.50 mm
h = 15.60 mm
Diagonal =  23.50² + 15.60²   = 28.21 mm

Sony RX1R II diagonal

w = 35.90 mm
h = 24.00 mm
Diagonal =  35.90² + 24.00²   = 43.18 mm


Surface area

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

X-Pro3 sensor area

Width = 23.50 mm
Height = 15.60 mm

Surface area = 23.50 × 15.60 = 366.60 mm²

RX1R II sensor area

Width = 35.90 mm
Height = 24.00 mm

Surface area = 35.90 × 24.00 = 861.60 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

X-Pro3 pixel pitch

Sensor width = 23.50 mm
Sensor resolution width = 6277 pixels
Pixel pitch =   23.50  × 1000  = 3.74 µm
6277

RX1R II pixel pitch

Sensor width = 35.90 mm
Sensor resolution width = 7976 pixels
Pixel pitch =   35.90  × 1000  = 4.5 µm
7976


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

X-Pro3 pixel area

Pixel pitch = 3.74 µm

Pixel area = 3.74² = 13.99 µm²

RX1R II pixel area

Pixel pitch = 4.5 µm

Pixel area = 4.5² = 20.25 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

X-Pro3 pixel density

Sensor resolution width = 6277 pixels
Sensor width = 2.35 cm

Pixel density = (6277 / 2.35)² / 1000000 = 7.13 MP/cm²

RX1R II pixel density

Sensor resolution width = 7976 pixels
Sensor width = 3.59 cm

Pixel density = (7976 / 3.59)² / 1000000 = 4.94 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

X-Pro3 sensor resolution

Sensor width = 23.50 mm
Sensor height = 15.60 mm
Effective megapixels = 26.10
r = 23.50/15.60 = 1.51
X =  26.10 × 1000000  = 4157
1.51
Resolution horizontal: X × r = 4157 × 1.51 = 6277
Resolution vertical: X = 4157

Sensor resolution = 6277 x 4157

RX1R II sensor resolution

Sensor width = 35.90 mm
Sensor height = 24.00 mm
Effective megapixels = 42.40
r = 35.90/24.00 = 1.5
X =  42.40 × 1000000  = 5317
1.5
Resolution horizontal: X × r = 5317 × 1.5 = 7976
Resolution vertical: X = 5317

Sensor resolution = 7976 x 5317


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


X-Pro3 crop factor

Sensor diagonal in mm = 28.21 mm
Crop factor =   43.27  = 1.53
28.21

RX1R II crop factor

Sensor diagonal in mm = 43.18 mm
Crop factor =   43.27  = 1
43.18

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).

X-Pro3 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 Fujifilm X-Pro3, take the aperture of the lens you're using and multiply it with crop factor.

Crop factor for Fujifilm X-Pro3 is 1.53

RX1R II equivalent aperture

Crop factor = 1
Aperture = f2

35-mm equivalent aperture = (f2) × 1 = f2
