My first impressions of the NiSi products were extremely positive but how would they perform in practice? I've been out and about putting them to the test. The first thing I've come to do is to leave the 77mm reducer attached to the adaptor ring and holder. This means that when not in use, I can still protect my lens with my standard 77mm lens cap. Otherwise, I would be looking to purchase an 82mm lens cap. In general, I have found that the system fits beautifully together with the spring loaded knob mechanism providing a positive latch and confidence that nothing is likely to come adrift. As mentioned in Part 1, the fit of the filters in the holder is quite tight but I tend to fit these 'off the camera' anyway and then adjust as necessary. One thing which is most noticeable is how much less susceptible to dust these glass filters are compared to resin types. I have found in the past that the very action of cleaning resin filters simply generates more static and hence attracts more dust. With the NiSi filters, a very occasional wipe with a lens cleaning cloth was all that was needed, and static just wasn't an issue. Circular polariserOne aspect of the system which I was particularly interested in was the polarising filter. As mentioned previously, this ultra slim filter screws directly into the adaptor ring and ahead of any other filters. I must say, this seemed a little fiddly at first, the filter is so slim that there's not much to get hold of without touching the glass. However, with practice, this wasn't an issue and soon became second nature. The filter rotates freely using the knurled wheels and this provides a wide and gradual range of adjustment. Shooting at midday is always a challenge, but from the following images it can be seen how the polariser gives superb saturation and clarity to the sky and clouds and also brings out the detail in the foreground rocks. The slight reduction in light transfer of the polariser was sufficient to prevent the highlights being 'blown-out'
ND1000 10 Stop Neutral DensityI have been looking forward to using the ND1000 10 stop ND filter and an outing to Strathbeag with one of my 'Learn in the Landscape' students was an ideal opportunity. I had read many references to how colour neutral this filter was and I was keen to test this for myself.
These are jpg exports of the original RAW file. No adjustments have been applied except for levels as the light was changing rapidly between shots. It is clear to see that both the greens of the background grass and foliage and the tones in the foreground rocks are consistent between both images. I have found the same to be true of results using the graduated neutral density filters, not having to apply colour correction is a huge bonus - as I have often said, I much prefer to be out in the landscape taking photographs than sat in front of a screen! In conclusionTesting the NiSi filter system has been an interesting experience and I'll be adding further examples using the graduated ND filters in coming weeks. In a market dominated by a small number of manufacturers, could this recent addition bring anything new to the party? The answer is a definite yes. Yes, the quality and presentation of the product is impressive but this is matched by the optical quality of the filters. I have used the filters extensively in some challenging situations including mountain and coastal locations. They have proven to be scratch and dust resistant, and have an impressive colour accuracy. If you are planning on adding to or replacing your filter collection, I would recommend that the NiSi system is included in your shortlist.

One for the photographers this time around. The only filters I use are neutral density, both full and graduated to control and balance the amount of light reaching the lens, and occasionally a circular polariser where appropriate. The choice of filters has long been dominated by a small number of companies offering very similar products of similar quality (both optical and build) and at a not insignificant price. Refreshing then to find a new brand coming to the UK market offering not only more choice but also something a little bit different from the established competition. I have taken delivery of a selection of products from Chinese manufacturer, NiSi. Anybody stuck in the 70s and still thinking that only products from the UK or the United States can possibly be of any merit had better think again. This is high end optical equipment with a really innovative design approach. I'll be testing the NiSi V5 filter holder and circular polariser, ND1000, ND8 graduated, and ND8 reverse graduated filters.
I have used resin based filters for years and have discovered all too easily how vulnerable they are to scratching. They are also prone to attract dust due to static build up. The NiSi filters however, are made from high quality optical lens glass. What is described as a 'nano coating' is applied to both surfaces providing resistance to water and oil. Living and working in a coastal location, I'm particularly interested in this feature. I've long been perplexed as to how some manufacturers supply their expensive filters in what is essentially a tin or plastic box. Once again, with the NiSi products an attention to detail shines through and each filter is supplied in a soft lined leather storage pouch with a magnetic closure. An information card on the outside clearly identifies the contents.
One of the claims from NiSi is that their filters have a neutral colour cast. I'm looking forward to putting that to the test as I apply them 'in the field'. I'll be reporting back with my impressions of the equipment in use and providing more information on the actual filters in coming weeks.
We had a few days of extremely cold weather in the 'Far North' a week or so ago directly from the Arctic. Snow, hail and high winds but beautiful sunshine in between. The light has been too good to miss so out I went with camera and thermos, the two essentials of any photography trip. I have a need at the moment to shoot moving water, and there's plenty of that around at the moment. I'm also frequently drawn to the Achfary area. The River Laxford flowing well followed by lochs, birch, and not so distant snow capped mountains, Stack and Arkle as always in their splendour. I first drove to Kinloch Brae where a group of stags looked on as I negotiated the boggy ground. The stream I had in mind just didn't work out, too fast flowing with lots of white water and without the vantage point I was hoping for. A sudden hail storm confirmed that it was time to move on. With time to spare on the return journey, I stopped off to see what I might make of the many fishing boats moored up along the route.  Moving on to Loch Stack, I discovered an interesting viewpoint of the River Laxford ebbing and flowing with Ben Stack in the backdrop. I managed to capture this just before the heavens opened . . . again  As April comes to a close, I noticed on the drive home that the colours in the landscape were starting to change, the hillside of Beinne Spionnaidh showing the first signs of greening up. A whole new palette to work with.
