Duclos PLx1.7 FF Expander

Duclos PLx1.7 FF Expander


This Expander by Duclos grows the image circle on a Super 35mm lens to fit a Full-Frame sensor. Consequently, there is a T1.5 stop loss in light, and it also seemingly increases the focal length of a lens by 70%.

NOTE: Lenses faster than T2.0 will experience massive aberration.
