I have just received my SLR Magic Rangefinder which is a groundbreaking concept. It transfers focus away from the main lens focus ring onto a dedicated buttery smooth geared 240 degree cinema lens focus ring and attached to the main lens like a screw on filter.
With the main lens set to infinity, focus is done purely through the SLR Magic Rangefinder.
This means that the awkward to focus Kowa 2x anamorphic lenses are now as usable as an Iscorama.
It means Nikon glass can finally focus the ‘right’ way!
It also gives closer focussing abilities for lenses that have a long minimum focus distance (like the 2m of an Iscorama anamorphic) and prevents the focus breathing inherit in all non-cinema photographic lenses.
