Don't you then have to move the camera a ways back to get all your objects in
the image compared to larger camera angles?
This is what I tend to do, long ways away, small canera angle (anaogous to
"telephoto" in real photogs, the images there have very little perspective
compared to normal which in turn has less than "wide angle").
The downside of this is that if you are using fog or mist, your primary scene
objects may tend to grayout a bit.
And you still have SOME perspective, it's not completely an isometric rendering.
But I agree, if you can't get orthographic to work for you, try this.
