two valid points!!!

- i agree with 吴聚that focus length is a personal choice.  here is my personal take:  after using 24mm, i felt it is a bit too wide for me on the street.  maybe i am not that brave yet.    i feel 50mm is too narrow.   so, that is where x100s with wide angle adapter come in.  yes, i got that the 28mm lens adapter too.    

- x100s has choice of 3 or 6 fps in raw.  i felt that should be enough.  you are right that x100s wont have overall fast reaction as dslr.  i know that my shooting mentality and style will have to adjust from that of dslr.
