Re: Questions About Sensor Size and Pixel Pitch

Sorry about that, lol...

Got interrupted while posting...!!!

My question was, does a larger sensor size automatically mean a smaller pixel pitch?

For example, my a7Riii has obviously much higher resolution with its full-frame sensor than do my G5X and G3X with their 1-Inch type sensors.

Of course, the full-frame sensor has more pixels because of (at least) the larger sensor size, but do we know if there are more pixels per square unit of sensor surface area than on the PowerShot sensors?

Thanks in advance..!!!

In general smaller sensors tend to have more pixels per square unit than larger sensors. But there is huge variation of pixel sizes so it is not always the case.

The pixel size on a 20 MP 1" sensor would give approx 150 MP on a FF sensor. The sensor area of a FF sensor is approx 7.5 times the area of an 1" sensor.
