Adaptor rings of the right size are a key factor in the ease of use & success of a filter system. As the RF75/Seven5 system is smaller than its 100mm counterpart, Lee offer rings from 37.5mm up to 72mm for the RF75/Seven5 system; whereas the 100mm system only goes down to 49mm. This ensures that most rangefinder lenses and smaller cameras will have rings to suit them.
