Isometric in Blender

I used Blender for creating isometric sprites. But, this process needs  automatization.
So, I created a camera with an isometric view and set it at angle of 60 degrees.  Then, I set rotation point to the center. After that, I selected the camera and pressed Ctrl+D and R (rotate 45 degrees). Repeated this for each of 8 views. Now, render. You can select current camera with Ctrl+<camera number> and render with F12.
