I am in Japan for 2 weeks and of course Murphy followed me here. I am having some sort of weird shutter lag with my 20D. If I push it in half way to get the focus and then push it the rest of the way it takes several seconds to fire, upwards of 5-8. However when I just fire without the half focus it fires. It happens about 65% of the time and is getting to the point where I am missing shots because of it.
The shutter release on the extended grip does not have this problem so I thought maybe the contact is dirty or mucked up on the body's release. I tried blasting it with compressed air but no luck. Does anyone know of a way to clean underneath the button?
I have resorted to taking the pics upside down using the vertical grips release but is getting annoying.
If you have any ideas please help!
