Max It might be more accurate to refer to a lens of this type as a "restricted" macro lens, since it only works optimally over a modest magnification range. Slow double Gauss lenses of this sort respond extremely well to the technique of moving the front and rear groups at different rates during focusing, and I'm surprised that Zeiss chose not to do this.
