Just to clarify... Unlike most filters...some Nikon filters have a slightly larger ring diameter and do require a special hood...what I don't know is if that "slightly larger" part will make it unsuitable for the Sigma hood.
I have this lens. I used to use/own a 72mm B+W CPL with this lens and my 18-200 (sold) with the hood on and no problem. I did sell my 72mm CPL and instead went with a 72-77mm step up ring (all my filters are now 77mm). I don't use a CPL much with this lens -- mostly to remove the shine off of flora on bright days. I also have a collapsible 77mm generic hood which I can screw right onto my 77mm CPL if/when I need a hood with the CPL.

Hi Albert, thanks for the reply. That's exactly how I use a C-PL with the 200AFD, but I have an HN-30 for that. I would love a screw-on hood for the Sigma, but I really don't care for those rubber hoods. Know of any metal, 72mm scew-on's? I am getting this Sigma specifically for butterflies, dragonflies, and general use tele work. The butterfly/D-fly areas that I am in are usually either in bright sun or on water, so I will need a PL for those occasions. It's not an insurmountable issue, and I am considering taking a dremel to the Sigma hood or just taking it on and off like I used to do when I was shooting the 180/3.5. Anyway...I wonder if I could use a 72>67 step-down... I have some other sizes I can play with in the meanwhile.

It works great for butterflies and the Sigma 1.4x TC to give more reach. Below is a shot taken with the 150 + 1.4x TC at f/5.6 in a public botanical garden. With a narrower FOV using a TC you might be able to use a 72-67 step down ring without problems but this is just a guess. I have a plenty of step-up rings but no step down rings to test it. Of course it also may work without the TC
