Nowadays it's the 15 Ltd / 43 Ltd and 77 Ltd. However if you forced me to take only ONE lens then it'd be the Sigma 30/1.4.

I have two macro lenses. The Pentax 35mm Macro Limited and the Sigma 105mm DG macro. I moved up to the 105mm as I wanted to take insects from a distance, which is not really practical with the 35mm unless they are very tame.I am very pleased with both lenses. Both are equally sharp however for some reason I find the 105mm more sensitive to the depth of field and takes me longer to position and hit the sweet spot accurately. Probably age and shaky hands.
35mm @ 20cm = DoF of 0.86cm
105mm @20cm = DoF of 0.06cms
35mm @ 50cm = DoF of 6.1cm
105mm @ 50cm = DoF of 0.57cms
35mm @ 20cm = DoF of 25.6cm
105mm @20cm = DoF of 2.60cms
