The PLx Extenders have been designed for AbelCine by IB/E Optics to be compatible with a wide range of PL-mount lenses. This chart lists zoom and prime lenses that have been tested with the PLx2, PLx1.4 and PLx1.4 Mark II. Keep in mind that if the maximum aperture of a lens is greater than the maximum input aperture of an adapter it will need to be stopped down to achieve a usable image.
Recently I had the opportunity to test the brand new IBE Optics PLx1.4, which just started shipping this month, out in the field. I chose to test it alongside the PLx2 in a pure run-n-gun situation in various spots around Chicago.
