Bonkers Benro Aureole filter + camera lens adapter has us scratching our heads

Benro has announced The Aureole, “The First Detachable Multi-functional Filter Mount Adapter System”. It’s a lens adaptor and rear filter holder all in one (though at this stage we would like to point out that Canon already makes a similar EF-RF adaptor that takes drop-in filters).

Benro’s pitch seems to be that a lens adaptor is a much better place to put filters than on the front of the lens, saving both weight and bulk in the process. Adaptors like this only work, however, where you are using a lens with a long flange distance, e.g. a DSLR lens, on a mirrorless body with a shorter flange distance –  there needs to be space to insert the adaptor between the lens and the body.

At the moment, Benro has announced two adapters – an RC1 Canon EF to RF adapter, and RE1 Canon EF to Sony FE adaptor, though it hints that more might follow. Both have slots at the top and the side to allow the insertion of Benro’s new filter range.

The Aureole is basically a filter holder that goes BEHIND the lens – but it only works with Canon EF lenses on Canon RF and Sony FE mirrorless cameras right now. (Image credit: Benro)

How the Benro Aureole works

The filter frame itself can accommodate a single round or square filter, two round filters or a square and a round filter. Benro mentions polarising filters, ND filters and ND grad filters, but has not so far mentioned variable NDs or indeed pricing for these filters.

You can slide filters in from the top or the side. (Image credit: Benro)

The Aureole can take both round and square filters, both with toothed adjustment ‘racks’. (Image credit: Benro)

We assume the ND filters can be slid up and down to adjust the transition point – the filters have a gear ‘rack’ in the frame – and CPL filters can be rotated by a knurled wheel. There is a 1/4-inch tripod screw socket in the base, which could be useful for balancing heavier lens combos more effectively, and we like the idea that filters can be inserted from the top or the side.
