After much work and many sleepless nights, I have almost finished my work and I think I have brought the lens NXL to the point of being sold to the public. I thought if the test this week will be positive to produce it with Canon EF mount dumb to which you can add a Nikon adapter with iris aperture control. At this stage it allows to mount all Nikon and Canon lenses, in the future I will continue to work to enable the electronic control of the lenses.
