Arca D4 + lens ring/clamp?
I was about to order the complete google-recommended pano kit (http://www.nodalninja.com/products/u...tator-mini/77/) , but looking at it it looks like I already have some equipment that is being replicated in the kit: an arca d4 head. For those not familiar with it, it has 2 pans built into it, top and bottom, so is able to provide a level pan.
It looks like I may be able to just purchase a lens ring and the clamp that attaches to the lens? But I'm a bit confused with all the options... I'll be using this w/a 5d mk ii and a Sigma f3.5 lens... anyone able to clear this up?
