Thanks a lot for the help Brian. 
 
	Actually I am not been able to manually set shutter speed, aperture value and ISO at once on this camera.
 
	Maybe I am missing some step. I have talked to Sony customer care and they have arranged a call back for me.
 
	Once I will know how to set all these manually, I will try the settings mentioned by you and let you know the response. 
 
	Regards.
