Yesterday the shutter button on my 50D started acting eratic. Sometimes it works fine then it will take anywhere from 1-4 seconds to trip the shutter after the button is pushed. When using the shutter button on the Canon battery grip it works fine. The photos come out OK no matter which button is used. Tried different camera setting, batteries, CF cards, etc. Nothing makes the camera button work correctly.
I have never had to send in a camera for service so my question is where is the best place to send it?
Thanks
