我買左部d70唔係好耐，昨日出去影相，點知忘記關機就換左個鏡頭，而家開唔到機冇晒反應呀…係唔係壤左啦﹗有冇得救番？

MY EXPERIENCE CHANGE LENSE IS NO NEED TO TURN OFF,MAY BE IS OTHER PROBLEM,YOU SHOULD SENT NIKON CO. FOR CHECK.
GOOD LUCK !

用 DSLR 就係方便你換鏡頭, "忘記關機就換左個鏡頭" 絕不影響部機的運作.

或者可以試下按機底 RESET 掣

我通常時都唔息机換鏡頭甚至換CF 都冇問題。可能係你部机冇電？？有冇試過叉完電再開机、如果都係唔得、試吓好似yaund兄咁reset 試吓喇。如果都係唔得、咁就拿返Nikon修理！

It should not be related.

However, when your camera is on, the sensor has electric charge on it, it will attract dust. So by all means, turn off your camera before changing the lenses.

對唔住呀…我找不到有reset個掣呀﹗嗚…嗚救命呀﹗唔得就比Nikon啦﹗謝謝各位兄台的意見。
