Basically, doing what you said, it helps the camera focus right.
Getting some decent light on the models helps as well, actual daylight beats the yellowish tinge from artificial lights when taking photos.
Have some more pics of the armour side of things. Still got a Russ and Sentinel to put together, along with most of them needing finishing off.
