Reversing ring auto focus

I saw that these were available a few years ago but only for Canon (and I use Nikon and Fuji) so didn't pursue the idea or look into it further. FWIW, SRB are a well respected UK based company and specialise in mount adaptors (among other things). The aperture control aspect of the connections would be handy for Canons but at the sort of macro magnifications reversing lenses can allow, AF would be less useful IMO.

I was reading a diy site recently. They had built their own using an af macro tube, taken apart and wires extending the connectors.

Cheers Nod I stumbled across it when looking at SRB for something else, was curious more than anything else :)
