D3100 wireless flash?
My brother has a D3100 and he is trying to figure out wireless flash photography. I told him that every dSLR I've owned had the ability to remotely fire a same-brand flash if the pop-up flash fires. Now that I'm looking through the D3100 manual I don't see this as an option.
I don't want to steer him wrong. Does the D3100 have the ability to fire a wireless flash without the use of an additional accessory?
