yesterday morning, went to desa waterpark for a TM family day..brought my a300 along..
ok..at first,shot some picture..still no problem..smooth..
i turn on and turn off smoothly..no sound, no problem..

then, i want to turn on my camera again, and a loud sound n vibration comes out.. wat was that?
so shocked, tried to turn it off..and the noise n vibration occurred again.. its only happened when i want to turn on and turn off.. shooting,smooth..no problem at all..pics also clear..
what should i do? one suggestion is to send it to sony centre..i lost my warranty card, can i still send it? but have to pay rite?

are u sure? coz that sound kinda long plus with vibration..so scared mah..

i remove the lens and turn on the camera, no sound..
when i put the lens back only comes d sound..

gizmo_pony: yeah..that sound..but its longer n vibrating more..
