How to use Orthographic mode while keeping the same scale?

I’m trying to use orthographic mode so I can draw the 3d shapes identically.

Here’s my code without enabling the orthographic mode.

void ofApp::draw(){
    camera.setNearClip(0.001);
    camera.begin();
    ofNoFill();
    ofDrawSphere(0.0, 0.0, -1.0, 0.2);
    ofDrawSphere(-0.5, 0.4, -1.0, 0.2);
    ofDrawSphere(0.5, 0.4, -1.0, 0.2);
    ofDrawSphere(-0.5, -0.4, -1, 0.2);
    ofDrawSphere(0.5, -0.4, -1, 0.2);
    camera.end();
}

And here’s the resulting screenshot:

And as I said, I would like to draw all five spheres to look identical just like the one in the center.

So I added camera.enableOrtho(); but here’s the resulting screenshot:

Why they look so different and how can I fix this?
