It is well known that after the earthquake and tsunami in Japan on 11th March, many factories in Japan have been affected, including many camera and lens makers. Production has been delayed and completely stopped in some factories. This has resulted in camera and lens street prices going crazy.
As far as I know, Canon Hong Kong has officially raised the recommended retails prices of their products by 5-6%. Although Nikon Hong Kong has not officially announced any price increased yet, they are expected to do so at any time.
Raising official recommended retail price is one thing, but the main problem seems to be that no new shipment is arriving in Hong Kong and none are expected to arrive for at least the next few months.
Street prices of cameras and lenses are not only affected by official recommended retail price, they are also affected by supply and demand. At the moment, the demand is huge, and supply severely constraint. This has led to street prices going crazy. Many cameras and lenses have street prices that have gone up by 10 to 20% at least. Some products maybe completely out of stock, so no matter how much money you have, you will not be able to buy them.
Street prices are crazy and extremely volatile at the moment, so unless you really need to buy now, otherwise, it is probably not the best time to buy any cameras or lenses for now.
There is also very little point in updating and requesting me to check camera and lens prices at the moment because the street prices are simply too volatile and could change daily. If you really need to buy, then you just have to be prepared to pay a premium.
I will post update if there are any change.
