is it a shutter button problem or something else ?!?!?!?!?!?!?!?!?!?!?!?!?!

Are you using the flash when taking your pictures? Because if so, after taking a couple pictures the flash has to recharge, so the delay would be higher. If this isn't the case, try to give us more detail, for example what settings on the camera you're using, what the lighting situation is, and anything else that you think could be useful. Honestly, at first glance, this doesn't seem like a hardware or software problem.

Well the same is happening while shooting with/or without the flash doesn't matter on what mode is it ( auto program shutter priority manual ) although i'm constantly using manual mode but as i said the same is happening all the times and in all modes and it startet happening 2 mounts ago first only on one photo after that 3 - times after 5 -6 pics
now something about the lightning and that doesn't matters even at high day light studio light the same problem :S:S:S don't know what is really going out with the camera :S:S:S

please help cause i love this camera and i don't wanna buy a new one :D:S
