I have the 5DIII and will probably get the 100mm 2.8L IS, and I'd like to have a hand-held macro setup but not sure the best approach. I already have two yongnuo speed lights. I have 4 triggers and a few sync cords so they can be used off-camera...
I've seen those contraptions that look like a ring that attaches to the body, and speedlights can attach and be moved around. Is that the best route to go? Is there something else to consider? Any specific brands/products recommended? A better way of going about it? Any tips in general?
Although probably you have fixed your mind on EF 100mm 2.8L, but since you are going for handheld a little bit of more working distance can never hurt. So have you thought about Sigma 150mm OS 2.8 Macro?
PS: although this might not be a great plus, but I see that Mr. Neuro has said that for the Wimberly F2 bracket needs a lens with lens collar (which EF 100mm 2.8 L does not have to start with and you need to buy separately). The Sigma 150mm 2.8 OS has that lens collar out of box
