I have a Canon 16-35mm f2.8L Lens with a B+W thin filter unfortunately the original Canon lens cap doesn't work with the B+W thin filter and I used the poorly fitting lens cap that came with the filter instead. Inevitably because this cap didn't fit well I've lost the cap that came with the filter. Does anyone have a solution to my dilemma or could anyone recommend an alternative filter that could replace my existing filter.
