Ratios and magnification

1:1 is true macro, and it is same as 1.0x

2:1 would be 2.0x

1:2 is only a 0.5x

So when you know optical magnification (0.5x, 0.28x, 0.16x etc) or reproduction ratio (1:1, 2:1, 1:2 etc) then you can work out the size you get with sensor size.

1:1 with 4/3 sensor gives 17.3x13mm capture area.

1:2 with 4/3 sensor gives 34.6x26mm capture area.

1:1 with 35mm sensor gives 36x24mm capture area (3:2 ratio instead 4:3)
