I build plastic scale models, planes, helicopter and jeeps/trucks. The models measure 10 inches to 20 inches long, and 2 inches to 5 or 6 inches high. I am using the 35mm prime lens set up now, and it works good.
I set up a light booth. I have 2 daylight top led bulbs and 2 in front right side and left side. Camera is in the middle, about 1 foot to 2 feet from the object.
Sometimes I like close up photos, to pin point areas, like a door marking or show problem areas. Sometimes the 35mm does not show this. Would a 50mm prime or 85mm prime work better?
