In mid 2012 I picked up a partnership with 84.5mm camera filters (www.84dot5mm.com), which are Cokin P size width filters and concluded my review which you can find here. Since then they have released their professional line series which included a reverse grad, the difference with these filters were they were longer and much more usable than before and I found them a perfect accompaniment to the Nex 7. They were great for being compact enough where a Lee 100mm filter system fell down as too bulky. I couldn’t get the kit into my Crumpler bag for when I wanted to go really light, but with these I could.
However, I always knew that a 100mm filter set was needed as well and was pleased when they informed me they were planning to launch a series. Now I own the Sony A7R, which has slightly larger lenses and when mounted to standard Canon lenses a Cokin P Size filter is definitely too thin and you can see the edges, so the 100mm filters come back into their own.
There will now be a new brand, 100mm Filters Ultimate Line and are due to be released Q2 of 2014. However, some European dealers already have stock but will be available direct from the filter company soon. The price point will be 50 euro or £45 GBP for the Ultimate Line Filters. They are sized at 150mmx100mm (same size as Lee).
