Compare Lumix DC-S1R



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

Panasonic Lumix DC-S1R diagonal:

w = 36.00 mm
h = 24.00 mm
Diagonal =  36.00² + 24.00²   = 43.27 mm

Surface area

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

Width = 36.00 mm
Height = 24.00 mm

Surface area = 36.00 × 24.00 = 864.00 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

Panasonic Lumix DC-S1R pixel pitch:

Sensor width = 36.00 mm
Sensor resolution width = 8423 pixels
Pixel pitch =   36.00  × 1000  = 4.27 µm

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

Panasonic Lumix DC-S1R pixel area:

Pixel pitch = 4.27 µm

Pixel area = 4.27² = 18.23 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

Panasonic Lumix DC-S1R pixel density:

Sensor resolution width = 8423 pixels
Sensor width = 3.6 cm

Pixel density = (8423 / 3.6)² / 1000000 = 5.47 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
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

Panasonic Lumix DC-S1R sensor resolution:

Sensor width = 36.00 mm
Sensor height = 24.00 mm
Effective megapixels = 47.30
r = 36.00/24.00 = 1.5
X =  47.30 × 1000000  = 5615
Resolution horizontal: X × r = 5615 × 1.5 = 8423
Resolution vertical: X = 5615

Sensor resolution = 8423 x 5615

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

Panasonic Lumix DC-S1R crop factor:

Sensor diagonal = 43.27 mm
Crop factor =   43.27  = 1

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).

Panasonic Lumix DC-S1R 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 Panasonic Lumix DC-S1R, take the aperture of the lens you're using and multiply it with crop factor.

Since crop factor for Panasonic Lumix DC-S1R is 1, the equivalent aperture is aperture.

If your screen (phone, tablet, or monitor) is not in diagonal, then the actual size of a sensor won't be shown correctly.
