maxh3h3: you wana get 17-50 f/2.8 so that you can shoot in low light? what lens are u using? 18-55 or 18-105? my advise is to make full use of ur lens first...
fyi, f/2.8 will not help VERY much in low light. perhaps faster focusing...
f/2.8 allows u to shoot at 1~2 stops faster than ur kitlens (depending on wha aperture u use). the VR in ur lens already allow you to shoot 3-stop slower adi.....if u want 1750 because of the optics then i would say try both, but if u want it just because of the f/2.8, i would say think twice
i used 1750 on canon before, noisy and focusing is pretty slow, the nightmare is the QC of that lens, heard of its back/front focusing problem? mine was ok initially then the problem came after few weeks...very bad back focusing...
