I have been struggling with the flash busy signal on my new T2i. I can not take fast pictures with the continuous drive using the P mode. The shot rate drops down dramatically sometimes down to 1 pic/2seconds.
I was trying the camera in different settings at home when I realized that the flash was super fast as it should when I was close (within 6ft) to the object I am taking a picture of. When the object was further away such as taking a picture of our living room from the other side of our kitchen (ca. 15ft) the frequency of the pictures I could take in a given period was much much lower. In fact, as I walked away from the object, the frequency kept dropping.
Can somebody explain this phenomena to me (a very novice photographer)? May be the camera realizes the distance and flashes harder which decreases the freq. cause it takes longer to recharge. Is there a way to minimize the flash bursts?
