may want to try older shops like peninsula plaza ones/excelsior shopping ones.. should have ,but whether it is brand new, used.. i am not sure. you might wan to consider going 2nd hand ones in cs or those i said. if ur budget higher, might as well buy new d7000. probably similar priced to those new d90 at not so well known shops imo of course..
Do take some time to browse the forum. This is photographer's forum, not babysitting and spoonfeeding. Go to main page, scroll down, read, understand, click... not that terribly difficult and may others got the idea, why not you? Being new is no excuse for basic courtesy, reading the Terms of Service and spending some time reading before posting questions.
Thx you for adv.
You are right, I need to understand basic of photography. I just own Nikon d90 and 17-55mm lens. But I still confused purpose of 17 mean . My friend said 17-55mm lens is better for d90(dx). Still unclear of about lens purpose. Can you explain me,pls?
