While Kolari Vision might not have been the first company to announce the release of drop-in filters for the Canon EF to RF drop-in filter adapter, they are the first to bring them to market. Kolari Vision has now announced the release and immediate availability of a range of filters designed specifically for the Canon EF to RF drop-in filter adapter. All the filters are similarly sized which is a nice storage feature, although the glass part will vary in size.
Breakthrough filters announced their filters for the Canon EF to RF drop-in filter adapter a couple of weeks ago, but they don’t ship until later this month. Kolari Vision, on the other hand, has some of their new range of drop-in filters shipping already. And they have aluminium frames, not plastic, for maximum durability.
