Lee Big Stopper 100mm
£100, $140 without holder
Unless you already use Lee 100mm filters, when you buy this you’ll also need to purchase a Foundation Kit and adaptor ring, which can add up to £100 ($120) to the price of this square filter. All components are engineered to a very high standard, though, making it an attractive system – this particular filter is a real favourite with pro photographers.
The Big Stopper filter itself has to be used in the rear tray of the filter holder, and has foam padding around its rear edge. This is to stop any stray light from entering through the top, bottom or sides of the assembly.
In our tests, the light reduction proved true to Lee’s claims of 10 stops but our sample images, taken using both the D7000 and D610 cameras, had a noticeable green colour cast.
