+1 that the magnifications marked on the extending barrel are with the Canon Life Size Converter EF attached.

Without the converter, the magnification is read from the yellow #s in the focus scale window (lower left of your picture).   As shown, 1:1 with the converter, 1:2 without.

In the official specs of "Canon EF 50mm F/2.5 Macro", the max magnification is 1:2.

On the lens barrel, when extended, there's a mark 1:1. Does that mean the lens can produce 1:1 magnification?

I am a bit confused about this. Thanks guys.
