For this week shooting,  I chose uses Canon 5d to shoot. Because it’s very convenient carry it compare with the EX3 camera. By using 5D, I found the focus is not good on uses this camera, especially shoot movement. The sampling of the sensor is not very good.Shallow DOF is great in some cases but other times you may want Deep DOF to show what’s happening in the background.One more thing is you’ll also have very short record times,the battery can not be using in a long time. When we shoot, we even waited almost two hour recharge the  battery. I am getting crazy…
