The faster the aperture the more environment you can include in your shot without loosing the nice shallow DoF.

( I finally found the flickr page for the kodak aero-ektar 178mm 2.5 )

That's just unbelievable beautiful. Seems like all the people are using the Aero Ektar on a Speed Graphic?

So basically the Aero Ektar on 4x5 will give you the same "look" in terms of focal length and amount of DoF as the famous kubrik 50mm f/0.7 on 35mm does. Pretty amazing.

To get that look, you need sufficient DOF to have the person sharp from front to back and nothing else. So about 12 " of "sharpness" at whatever distance will get you full body using the focal length of your choice. It really isn't about having the largest aperture, its about understanding how to get the amount of DOF that you need for the shot. If you like the aero ektar look, then just get an aero ektar. But LEARN how to use it effectively. Otherwise, you won't get shots like that.
