Fotodiox WonderPana

Here are the two main pieces of the wonderpana. A backing and the thread holder that attached to the backing creating a smooth seal

The 10 stop is my favorite filter, here attached on the 14-24 2.8 Nikkor

The WonderPana system has an awesome lens cap so that I rarely need to remove the rig from my 14-24 lens
While the cap does have a large circumference, it isn't too much larger than the camera
The wonderpana also has additional attachements if you prefer square filters or even filters from brands not Fotodiox
There are high quality stepdown attachements so that you can use the filters on alternate lenses.
Here is the Nikkor 70-200 2.8 with the step down and 10 stop attached.
You can see the different opacities between the 3, 5 and 10 stop

I am excited and grateful to be able to join Fotodiox as a creative partner.  
Why is this exciting? Well Fotodiox is a cure to my woes. You see, there is this thing called the holy trinity. It is the trio of Nikon Nikkor lenses that are the best of the best. They are the 24-70mm f/2.8, the 70-200mm f/2.8 and the 14-24mm f/2.8. That last lens is the key! The Nikkor 14-24 2.8 is the #1 lens in my bag. It is practically perfection, aside from one flaw. It has a convex glass that protrudes from the end of the lens, so it cannot hold filters naturally. 
Well Fotodiox is like a knight in shining armor. Their WonderPana filter system is just what the doctor ordered. This system has created a seamless remedy to be able to filter the 14-24mm lens. Not only that, the system is so sturdy and well crafted that with the aluminum step down adapters I can also filter all of my other lenses. This is fantastic because now I can consolidate my whole assortment of various filters and keep the one system. While the 145mm filters are obviously quite a bit larger than the 77mm lens, there is not as much of an imbalance as you may assume. 
In the pictures above you can see the WonderPana in various forms. The rear ring and front cap screw together from each side of the lens barrel. This creates a firm seal which prevents light leak (one of my biggest qualms with some of the square filter sets). Once the WonderPana is attached the outer cap has screw in threads in which you can attach filters like any other screw in filter. The only difference are the 145mm filters to use are a bit larger than the lens.
Additionally, in the images you can see the step down adapter to attach to the 77mm thread of the Nikkor 70-200 f/2.8. Other lens thread sizes are also available including 95mm, 82mm and more. Lastly, shown above are a 3, 5 and 10 stop filter made by Fotodiox of high quality premium neutral density optical glass.

Stay tuned for more filtration images and I look forward to the images my  Fotodiox will help unleash from my camera!
