I'm not sure that posting a product ad is COW ethical but the Sola ENG ad I just found is the first I've seen where Litepanels is showing that the ENG is not primarily for on camera use (as the ENG name implies) which their marketing material and the reviews I've seen, focus on.
You can see by the ad they're thinking of back, fill and softbox key use. Of course real world use would reveal real world value and flaws but this is really what I want to see in order for one to "pain with light" in a small office shoot environment. I don't expect "long throw" but that's not what I'm up against in a small office. I need to paint without cooking the subject or blowing the fuses.
