A discreet, understated accessory.....

...this is NOT.

Circular filters are 145mm, rectangular filters are 6.6inX8.5in.

Filter system for UWA lenses. Sorry about the image quality.

I love this lens and have been considering this Lee Filters system, but hadn't appreciated how large the glass is. Thanks for sharing.

This is the Fotodiox 'Wonderpana' system, not the Lee. I believe the Lee is a bit smaller, tho' I've no direct experience with it.

In this system only the ND Grads are rectangular. The CPL and non-Grad NDs are all 145mm circular.

Whoa! That's some substantial kit Dave.

I'd love the k1. Bit then I'd have to get the 15-30 . And then I'd need to get a filter rig like this . So one day, but not now.

Be great to see some images with this setup.

I can see now it is different to the Lee Filters, and the round filters are probably more manageable than the square type. I see that Pentax is introducing an ultra-wide angle prime lens in 2017 which, if it is around 20mm, might take a smaller filter rig and will definitely be in my wish list.

Substantial is right..

Now, if were half the size and a quarter of the weight, it would be great..
