When shooting concerts. Try using a wide aperture or higher ISO. This is to help make the camera use a higher shutter seed. 
High shutter speed is needed because it allows you to freeze the subject. Magazines and Newspapers doesn't like pictures with motion.
Here is an example from me. I was keeping the shutter speed at 1/200 throughout the concert
ISO was around 4000 and F10. No flash. If you ISO can't go more than that, just pump. Don't worry about the noise. 
I was using F10 because I needed it to be super sharp as my pictures will be distributed to the media on the spot after the concert. No time for PP or chance to look through my own photos.
The picture was on Hot Magazine website and The Star newspaper. 

round RM200 *hahahaha* but if more expensive and better price for performance also tell me.. thank you..

in built flash also can be adjust power.... just adjust it and use some diffuser, good edi....

last time i sent my kit lens to fix af motor cost me 300 dollars.. if its 300 dollars to fix it, might as well get a new lens

Guys what do you all think about this composition?Seems a lil wrong there.. Should compose it higher right? If so, i'll go back and shoot again
