Unfortunately, I don't have the Sekonic C-700 this time around. It was borrowed from our rep, but he's no longer with that company. Although, @DELO72 had been interested in getting one for himself....
He specifically said no adapter, he wants a "true" Fresnel. I haven't seen any LED "true" fresnels in the past but maybe someone has one out now. I'll definitely be looking for one.
I haven't seen a full color led Fresnel here, but Altman has a pretty nice white LED Fresnel. Optics and color of white are beautiful. It was a little steppy, but the rep told me they were having problems with the controller and that it works great on full light board.
I agree on the truss, it looks awesome. The amount of truss you can pack into a single dolly is sick!
