1, You are a funny guy.
2, The 1645 blocks the build-in flash.
3, It's a very long lense at 16mm, you can barely shoot 1/60 handheld. The DA15 being a much more compact lens it's definitely possible to shoot at 1/30s handheld.
It's a perfect travel lens IMO. I will sell my 16-45mm soon. Originally I wantd to switch to the Sigma 17-70mm. Now I am thinking either the DA15 or the new Voilgtlander 20mm. I am leaning toward the Voilgtlander myself.
The 16-45 definitely isn't distortion free at 16mm, while the 15mm looks very good from Ned's samples. I have to disagree on the shutter times, though, IMHO the long barrel just makes it easier to use long shutter times. I use shutter speeds down to 1/8 on a regular basis at 16mm. I even managed to shoot a sharp pic at 1/4 with the SR off (accidently).
The 15mm is high on my wish list now, but I will no doubt keep the excellent 16-45 for those times when a zoom comes handy.
