Oh can limit the focus? Then it's really a good lens. Yeah aperture changes... If I'm not mistaken all macro lenses are like that?

about the sharp focus noise which i previously reported , the shop will bring it back to nikon centre for evaluation...

The Nikon flashes are better built, and have metal hotshoe mounts. Try mounting yours, hit it against the wall, and see the plastic mount break, not replaceable, and you end up having to buy a new flash. I have also seen cracked bodies and all. I abuse my Nikon flashes for years and none have fallen apart yet.

To do off-camera flash, either get one that is CLS compatible like SB600/700//800/900, or use a radio trigger. Yongnuo, Phottix and various other brands offer radio triggers. Only Nikon's own CLS and radiopoppers support full TTL off camera, for the rest you will need to use your flash in manual mode (AFAIK, correct me if I'm wrong). Downside is, Radiopoppers are not available in Malaysia AFAIK due to radio frequency regulations, and importing them on your own is technically illegal, and also they're very expensive.

Have to warn you though... going into lighting is like opening a whole new can of worms, and a whole new lot of pocket hurt.

i think most probably no... bcoz msian power socket are not like that.. indo version yes..

mine is like that. D3100 though. 

really? not sure if new batch start already include that socket... but it help a lot during travellig..

The one at the left is RM34.20(price after 40% discount for members with 40% discount coupon, normal member gets 30% off, non-member gets 20%); The one at the right is RM39.90(price after 30% discount for members, non-members get 20%)

It's quite difficult as it's very far from my place, and this fair going to end at 28th. I don't think I have the time to go back there already as there a few exams coming soon.  

oo thnx for advice
but i dont have the body 
save for the next hehe
