Hi all

i have face with a very annoying problem ... and i am going on for a trip soon,..

I have brought is lense for only a few weeks and there is an intermittent problem of focusing and aperture problem..

the lense simple refuse to focus sometimes, the and the aperture in the lense did not open up back to 3.5 after a shot is taken...it just stays there...but the shutter is already closed..this problem will appear whether i switch on and off the IS function.

please help....
