Adapter and accessory maker Fotodiox has announced two adapters to enable the use of filters with wide-angle lenses that have large convex front elements. The WonderPana Filter systems are based around adapter hoods that allow 145mm circular filters or 6.6″ rectangular filters to be used, via an adapter. Each system comes with a lens cap that mounts on the hood, allowing the lens to be stored and protected without needing to repeatedly remove the adapter hood. A variety of adapter and filter kits are available for a range of Super-wide and Ultra-wide lenses.
