Fotodiox WonderPana MC CPL Slim Filter 145mm

The Fotodiox WonderPana MC CPL Slim Filter 145mm is a multi-coated circular polarising filter designed for use with the WonderPana filter holder system, built for ultra-wide lenses that can't use standard screw-in filters.

What this filter does

A circular polarising filter cuts reflections from water, glass and wet surfaces, and deepens blue skies in a way no amount of post-processing can fully replicate. The 145mm format is specific to the WonderPana ecosystem, which is engineered for front elements too large for conventional filter threads. The slim profile helps minimise vignetting — a real concern at ultra-wide focal lengths.

Key features

• 145mm diameter sized for the WonderPana filter holder system
• Multi-coated (MC) glass to reduce flare, ghosting and internal reflections
• Slim profile to minimise vignetting at ultra-wide focal lengths
• Circular polariser design for cutting reflections and saturating skies

Who is it for?

If you shoot landscapes, architecture or interiors with a super-wide or fisheye lens mounted on a WonderPana holder, this is essentially the only CPL option designed to fit properly. It's a niche but important piece of kit for photographers who've already invested in the WonderPana system and want polarised control in the field without swapping to a different setup.

Buying used

Picking up a pre-owned Fotodiox WonderPana MC CPL Slim 145mm makes a lot of sense given how rarely these see heavy use — polarisers tend to spend most of their life in a bag. Every used filter on Camera-tweedehands.nl is individually inspected and comes with a minimum 12 months warranty.
