The solution to vignetting rectangular filter holders. 3DP Idea’s filter slots let you stack 3 filters on a Lee holder without vignetting at 16 mm.
An innovative approach to mounting rectangular filter holders (Lee in this case) to a lens using the lens hood’s bayonet mount.
An innovative approach to mounting a rectangular filter holder (Cokin Z-Pro in this case) to a lens using the lens hood’s bayonet mount.
B+W’s older style of circular polarizer. Provides solid image quality and reasonably neutral color though it blocks nearly 2-stops of light too.
B+W’s XS-Pro line are their newest line of filters aimed at modern photographers. They combine the same great B+W optics and coatings with a new thinner mounting ring that still retains front threads.
Breakthrough Photography’s highest end entry in to the circular polarizer market, it delivers on the promised neutral color and minimal darkening, and does with a design that’s easy to feel and use even with gloves on.
Cokin’s Z-Pro holder for 4″ rectangular filters. Holds filters, but the mounting system is flawed and it’s not really suitable for 10-stop ND filters. Newer designs (e.g. Lee, HiTech, or Breakthrough Photography) work better.
Original version of HiTech’s 10-stop neutral density filter to extend an exposure significantly. My testing showed a strong, often uncorrectable, color cast that rendered this useless for anything but black and white photography.
Lee’s 4″ filter holder kit provides a well built foundation for using 4″ rectangular and square filters with a quick detach mechanism to get the filter on and off quickly.
