I own the Sekonic L-508 and find it to do all that I want without any extra fussing about it. I've owned it for about a decade. It takes AA batteries. It has great battery life. And I think that it does all that I want I don't find it wanting in any way.

My own thought is that if you're going to spend hundreds (or more) on a camera system, then spend a bit more for a high-quality light meter. It's a one-time purchase.
