This is the actual size of the Dynax 7D sensor: 23.5 x 15.7 mm
The sensor has a surface area of 369 mm².
There are approx. 6,310,000 photosites (pixels) on this area.
Pixel pitch, which is a measure of the distance between pixels, is 7.64 µm.
Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.
Pixel or photosite area is 58.37 µm². The larger the photosite, the more light it can capture and the more information can be recorded.
Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. KonicaMinolta Dynax 7D has a pixel density of 1.71 MP/cm².
These numbers are important in terms of assessing the overall quality of a digital camera. Generally, the bigger (and newer) the sensor, pixel pitch and photosite area, and the smaller the pixel density, the better the camera. If you want to see how Dynax 7D compares to other cameras, click here.

Diagonal
Diagonal is calculated by the use of Pythagorean theorem:
where w = sensor width and h = sensor height
Diagonal = √  w² + h² 
KonicaMinolta Dynax 7D diagonal:
w = 23.50 mm
h = 15.70 mm
h = 15.70 mm
Diagonal = √  23.50² + 15.70²  = 28.26 mm 
Surface area
Surface area is calculated by multiplying the width and the height of a sensor.
Width = 23.50 mm
Height = 15.70 mm
Surface area = 23.50 × 15.70 = 368.95 mm²
Width = 23.50 mm
Height = 15.70 mm
Surface area = 23.50 × 15.70 = 368.95 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 
KonicaMinolta Dynax 7D pixel pitch:
Sensor width = 23.50 mm
Sensor resolution width = 3077 pixels
Sensor resolution width = 3077 pixels
Pixel pitch =  23.50  × 1000  = 7.64 µm 
3077 
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 
KonicaMinolta Dynax 7D pixel area:
Pixel pitch = 7.64 µm
Pixel area = 7.64² = 58.37 µm²
Pixel area = 7.64² = 58.37 µm²
Pixel density
Pixel density can be calculated with the following formula:
You could also use this 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 
KonicaMinolta Dynax 7D pixel density:
Sensor resolution width = 3077 pixels
Sensor width = 2.35 cm
Pixel density = (3077 / 2.35)² / 1000000 = 1.71 MP/cm²
Sensor width = 2.35 cm
Pixel density = (3077 / 2.35)² / 1000000 = 1.71 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
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 → 

Resolution horizontal: X × r
Resolution vertical: X
KonicaMinolta Dynax 7D sensor resolution:
Sensor width = 23.50 mm
Sensor height = 15.70 mm
Effective megapixels = 6.31
Resolution horizontal: X × r = 2051 × 1.5 = 3077
Resolution vertical: X = 2051
Sensor resolution = 3077 x 2051
Sensor height = 15.70 mm
Effective megapixels = 6.31
r = 23.50/15.70 = 1.5 

Resolution vertical: X = 2051
Sensor resolution = 3077 x 2051
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 
KonicaMinolta Dynax 7D crop factor:
Sensor diagonal = 28.26 mm
Crop factor =  43.27  = 1.53 
28.26 
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).
KonicaMinolta Dynax 7D 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
KonicaMinolta Dynax 7D, take the aperture of the lens
you're using and multiply it with crop factor.
Crop factor for KonicaMinolta Dynax 7D is 1.53
