1:1 is that the subject size is equal to the sensor in live size.
if the subject is 1cm, it should be as big as 1cm on the sensor.
but bigger mega pixel will make it looks bigger, but if every 'MP' sensor picture were to resize to 800px, all pic of the 1:1 should be more or less the same size.
2:1 is bigger then the sensor. for example, FF (35mm cross) normally a 5 cent coin is around 16mm diameter across the sensor, but the 2:1 makes the coin 32mm over the sensor, mean u would capture a near fullsize frame...
1:2 means its half, meaning the coin will looked like 8mm on the 35mm sensor.
