View Full Version : New Filter Adapter for 7-14 Pro

7th January 2016, 12:49 PM

Hi All,
Some may remember some time ago when this lens was first release I made a 'Frankenfilter' adapter using a Cokin P499 universal adapter with a Lee ring stuck on it. Times have changed; I recently became an approved supplier for Nisi filters so I decide to create an adapter that would fit the Nisi holder to the 7-14 Pro, and it works fantastic, The pictures are from the banners on my website.
The adapter is textured nylon to prevent reflections and has an internal gasket to give a very tight fit, it won't come off. Along with the adapter are two 'plates' (see rear image) which fit to the back of the holder onto the existing rail screws. Attach the holder to the adapter by pulling the pin as with other holders, and slide the plates over which then overlap the join and lock the holder to the adapter, but still allowing rotation. This is an extra precaution against the holder coming away from the adapter.
Vignetting-using two slots on the holder there is zero vignetting. Rotating the holder introduces a small amount which is removed at around 7.5mm. As the rails are standard rails with a cover plate (important) there is no issue of light leaks using NDs for long exp.
I developed this for Nisi for two reasons;
1 Filters are the highest quality optical glass not resin. They are multi coated, neutral, and have an outer nano coating for protection. NDs are low reflection, neutral and have a higher light transmission into the corners than the Big Stopper.
2 The filter holder is based around the clever polariser/adapter. The adapter is a wide angle lens ring which accepts a screw in polariser. Mechanical wheels on the side allow the polariser to be turned which means no faffing when filters are inserted. Being close to the lens means it's a sealed unit with no light leaks and no rear reflections entering the lens. It can be used as a polariser in its own right or as a lens ring for the holder with or without the polariser. Genius! Its available as 100mm filters and 70mm for mirrorless systems.
Thanks for reading! More info available on my website http://www.philnortonphotography.co.uk/olympus-714-adapter.html

Well done on producing the adapter Phil, I hope it's a success.

I'm considering buying the 7-14mm lens, I'll bookmark your page in case I find I need the adapter and filters.

Thanks Dave
It's a great lens, even better having the choice of filters :)

Phil, I already have the Lee 100mm filter system, presumably for this to work all I would need to order is the adaptor and filter holder.

Hi Graham
Yes exactly right it accepts any 100mm filters. It's supplied with the polariser and rings for 62,72 and 77. They fit on the back of the main adapter. For other lenses eg 12-40pr you just get a cheap step up ring 62-67. FYI If you have other systems there's no issues with needing wide angle adapters. It fits my Canon 17-40L with no vignetting

Phil ok I will try this, order done.

This looks great for when I get a 7-14 but I am using Formatt Hitech 85 mm filters so would need to change systems.

You need 100mm filters for the 7-14 Alf because of the size of the lens. Your 80 system wouldn't be redundant though it's still useful on smaller lenses. I use the 9-18 when I want to be compact and use the Nisi 70mm on that.

I've just placed an order, too.
I've already got a Lee 100mm Big Stopper that's in reasonable condition so I'll see how I get on with that for now plus the polariser that comes with the mount.

Hi Mark
Many thanks I just sent you a confirmation email.

Thank you Mr Norton for news about this product. As someone who already owns the Olympus 7-14mm f2.8 Pro lens, I am very interested in it.

I am a stranger to the Nisi filter system but from what I can see it works similar to the Cokin system but obviously more specialised and far better quality. Just so that I have understood the information on your links correctly >

The basic essentials are your own Norton Filter Adapter (as shown) and the Nisi V5 100mm Filter System, right? With that I should get all the attachments necessary to make the combo work plus one circular polarising filter, right?
With that basic kit, would I then be able to add over time a few of the expensive specialised Nisi filters (like the Reverse Grad etc)

Have I got that right or have I missed something? Would be grateful for the information.

Hi Loup

Yes you have got that completely right. As you know all square filter systems have a holder, which attaches using lens rings; Nisi redesigned the the system so that the lens ring itself is also an adapter for a polariser, with an internal mechanism and wheel on the side to rotate the polariser. That means the system can be used with a polariser at the rear, without the polariser, or as just a polariser without the holder. It's very clever and with the quality of the filters thats why I developed the 7-14 adapter for this system. Just to make you aware, you cannot use the polariser with the 7-14. Its not a limitation of the Nisi system, rather the nature of the 7-14. To avoid vignetting the lens hood projects through the holder and prevents its use. The only polariser you can use with the 7-14 is a square slot in cpl. However it can be used with all other lenses. The Lee and other systems adopt a polariser on the outside, as the last filter. At 105mm they are too small and vignette beyond use on the 7-14, and they are prone to reflections from the rear. All in all the Nisi system is 1/3 the cost of even the best known system if you compare the cost of adapter rings, holder, polariser, and the extra ring needed to fit the polariser. And the polariser is multi coated.
The Nisi system includes adapter rings for 67 72 77 and 82mm lenses. For other lenses all thats needed is step up/down rings. With the adapter you get the adapter itself, the rear retainer plates, spare gasket and nuts just in case they are needed.
Yes of course you can add Nisi filters over time. They are higher cost but overall no more expensive when you account for the cost saved with the holder/polariser combo. They are optical glass and more neutral than others. Optical glass has better image quality and although some are concerned about breaking, 2mm glass is very tough; plastic filters also break if dropped. They have an outer coating which protects the graduations from scratches.
Hope that helps and I have gone into more detail than perhaps needed for the benefit of other too.

Thank you. One of the things that I plan to use the 7-14mm is to take it to the various US National Parks for landscape photography. I regularly visit the US and following my planned retirement from diving this year, hope to have more time to re-discover my old hobby of landscape photography.
