DA35 limited f2.8 macro. There are others, but that's the one you want. The fact it also doubles as a damned good standard prime, and it does macro, and both of them very well; it makes it the perfect starter prime. (But it's not great for insects that fly, due to the really close minimum focussing distance)
The 100, whilst fantastic, isn't that great as a walk around prime. You could leave home with the 35 ltd, and that's all you need. If you took out the 100, you will always have the 18-135 in your bag.
Just get the DA35 f2.8 limited. No one has ever been disappointed in that purchase. (It is better for macro shots of things that can't fly, than things that do, but it's also one of the best 35mm standard primes in the normal range money can buy)
honestly, as prime lenses go, the DA35 macro is one of the best there is (and to others responding here: the OP has 1 lens, a (good) zoom. Why not combine that with the DA35 macro?) It's one of the easiest macro lenses to use with AF, and if the OP decides to move to a 100mm lens later on for bugs, they still have a fantastic standard prime.

Reason: Other people were recommending the 100, I disagree
