The WonderPana FreeArc provides the freedom to use and rotate 6.6" and 145mm filters on your Wide and Ultra-Wide Angle Lenses. Because of the construction of these lenses, it's normally impossible to install filters as there are no filter threads. Additionally, standard filter sizes are not large enough to adequately cover the lens's wide angle view. The WonderPana FreeArc changes all that by providing a complete kit for mounting our collection of both round and square filters. The all-metal Core attaches directly onto the lens with a secure mounting system. With The Core in place, you can now mount any of Fotodiox's 145mm round filters.
The WonderPana Freearc you see on this page is custom engineered to fit the Sony FE 12-24mm f/4 G E-Mount Lens. It will not fit other lenses, so it's important that you chose the correct Wonderpana Core system for your particular lens model. You will have to remove your lens from the camera in order to mount the filter holder.
For even more filter flexibility, mount the 6.6" Filter Brackets (these mount without tools on either side of The Core). Once attached, you can easily slide in our 6.6” square filters, which are among the largest and most durable in the business. With the FreeArc, the filter stage is rotatable 360 degrees. The Wonderpana FreeArc can accommodate either two square filters, or one round and one square simultaneously.

It's about the only CPL filter/holder for ultra wide angle (12-24mm for me) so it's a good thing it works. Be sure to get the $200 version of the CPL filter not the cheap one, the glass is much nicer. I actually had to return the Amazon order because the filter glass was streaked so I just ordered everything direct from WonderPana so they could check the filter glass before they shipped
An absolutely fantastic product for camera lenses that otherwise would almost be impossible to put a filter on. The glass is extremely high-quality.
lubricant leaking is the major problem (pictures so the holder surface is covered by the lubricant) and it is really hard to mount filters on it. The lubricant just went on my lenses at the end so I have to clean my hand and lenses every time. In order to install this filter, we have to unmount the lenses and screw it on it while dust can go in our cameras easily. So, I have to blow out dust every time I switched to use this filter holder.
