亲爱的rachel，我觉得canon50D是很够啦，我的20D用得也蛮好的,最近我一般都喜欢用数码卡片机，出行轻快多啦：）
至于镜头，我请教了一下我的朋友bryan,他回答如下：
canon d50 sensor has a 1.6x field of view crop factor, so the 17-40mm lens effectively becomes 27.2-64mm lens for a full size sensor's field of view. the wide angle end is good, the telephoto end is a bit short. then it also depends on your friends shooting style. for me, it might enough since i'm not so into telephoto shooting, but again, it all depends. another factor you need to take into account is that if you do wind up choosing a lens with long telephoto, it'd better have some kind of stabilizer, it makes your shots several stops better. f4 is a bit slow, but not too bad, and if you crank up iso, it's usually good enough, and for beginners it's not worth spending extra money on a f2.8 lens, let along the extra weight.

基于此，要么你搞个17-85mm的?

嘿嘿嘿，好白相。老二也像爸，长相上还暂难分，不过那个眉眼透的还是一样的味道，特别是那张睥睨的，叫他papa做一个，保准一个味道，哈哈。好呀，有子有女万事足了。then,u are in坐月子now,huh

在香港的那帮印度人还好嘛，没碰上要合影的，也许是像你说的见得少才会。不过我倒是进去过他们的“老巢”重庆大厦做过一回外星人


btw,maotouzi,偶还是觉你嘟起嘴生气的样子最灵，嘿嘿
