Nikon D90 And Canon Speedlite 430EX (this is NOT the II model, it's the first one) Would it work on that camera body? I can't find anywhere where it would say what camera it would work on :O Friend is wondering if she can borrow it from me but we are trying to figure out if it would work with her camera. I apologize in advance if this is not the correct place to ask! Thank you for your help!
