A. Camera is quite resource-hungry and takes a second or so to start even under the best of circumstances. However, there's an extra factor, due to it being assigned by default to the left function key on the standby screen. Any assignment on this key will have its action delayed by a second or so because the device has to check you're not also about to press '*' to activate the keylock.
Assign 'Camera' to the right function key and you can then access it quite a bit faster!
