I'll be upfront with you. Ever since I bought my first filter set in 2007 (when I had a Nikon D80), I've only ever bought filters from Lee Filters. When I first started looking for a filter system, everything I read said that Lee Filters were the best. Pricey, but the best.
Over the years I've built up a reasonable size collection of filters from Lee. Up until now the only filter I have replaced was the original circular polariser for the new, slightly thinner landscape circular polariser. I've never had to replace a filter because of a fault and I still use the filters that I originally bought in 2007. So if you are looking for a comparison to filters from other manufacturers, I'm afraid this isn't it.
Goodbye Little Stopper and Big Stopper
With all that said I have just sold both my Little Stopper (6 stop ND) and Big Stopper (10 stop ND). These are filters I have used a LOT. So did I not need them anymore or did I buy ND filters from a different manufacturer? Of course not! All I have done is simply replace them with 6 stop and 10 stop ProGlass IRND filters from Lee Filters.
Apart from being more expensive than their Stopper equivalents how do these ProGlass IRND filters differ? Should you sell your Stopper filters and replace them? Do you need both Stopper and ProGlass IRND filters? In the video below I aim to answer all those questions!
Hello ProGlass IRND
As you'll have seen in the video my conclusions about whether these new ProGlass IRND filters are a must buy aren't clear-cut. It's difficult to give a general conclusion as everyone's needs and budgets are different. The fact that the ProGlass IRND filters don't actually replace the Stopper range also adds a little complexity to the decision.
So all I can really do is talk about my own decision to sell my Stopper filters and buy the ProGlass IRND filters. For me, it has very much been money well spent. I particularly like the lack of colour cast and vignetting. While both these can be corrected or enhanced in post-processing, I much prefer seeing a more neutral/accurate representation of the scene on the back of the camera at the time of capture. I also like the fact that calculated exposure times are far more accurate.
Here are the images from the video should you wish to take a closer look.
