If your camera is self-cleaning and you are still getting dust problems, you might want to look into it a bit more carefully as this shouldn't normally happen. (Well, maybe once in a long while, but normally you can go years between cleans.) If it is a regular issue for you, there will be something wrong, perhaps excessive dust in the sir when you are changing lenses (unlikely in the studio); maybe excessive lubrication on the internal moving parts (not normally a factor but the odd model has had a problem with this); or simply holding the camera incorrectly at start-up time. (Assuming you have the normal setting, which is for the sensor to self-clean for a second during start-up, hold the camera level. This allows the dust dislodged by the vibrating sensor to settle towards the base of the casing, where there are sticky pads designed to latch on to it and stop it floating up again.
All that aside, it's good to have a cleaning kit. You should almost never need it, but when you do it's a life-saver!
