Yeah, it scaped me completely. But for starters I always prefer to recommend a good quality and cheap zoom, hence the tammy. If weight is your priority the DA40 will blow any other lens out (and comparing to even smaller lenses, blow them in IQ). The DA 40 is one of the sharpest and with great image rendering of the ones I've seen. I haven't used it but I've seen photos from my friends and they are spectacular out of the camera.
If you don't care about fixed focal length lenses, the DA40 is a "cheaply priced", high quality lens that you really wont regret, as mz-3 said.
