The image forming area is less than the total area, and it is quite common for companies using the same sensor to choose slightly different border masks. For instance, Nikon's and Sony's often have different pixel counts. One reason is that different companies pattern noise measures need different numbers of black masked pixels.

But we're not talking about the effective pixels here. There's a difference in the total number of photo sites. Can this number vary if the sensor is the same?

Panasonic G3
Effective pixels: 15.8 megapixels
Sensor photo detectors: 16.6 megapixels

Panasonic GX1
Effective pixels: 16.0 megapixels
Sensor photo detectors: 16.6 megapixels

Olympus E-M5
Effective pixels: 16.1 megapixels
Sensor photo detectors: 16.9 megapixels
