FRENZY15
I personally can't afford these but they are amazing filters and NiSi has a 15% off sale on their entire site. I figured some of our photographers here could benefit, especially with vivid around the corner.
Great for long exposure photography and absolutely destroys the plastic stuff you find on eBay.
Personal favourite is

Comes with ND1000 and ND64 stoppers for long exposure, a Graduated ND16 for taking HDR images, a Natural Night (gimic filter if you know how to use lightroom imo, but it has its uses), a polariser for reflections, case, holder and adapters. - $1,099.00 inc. GST comes down to $934.15.
wow looking at their 72mm CPL filters, quite expensive! Is the quality that good? This puts them on par with B+W and Hoya HD filters
