If this works...we have a revolution :)

Absolutely fascinating.

If I'm reading this right, a full frame 50mm 1.8 could be 'converted' to a 35mm 1.2 suitable for an APS-C sensor?
 
The idea is at least 20 years old, as I understand it. Nikon, Fuji and Kodak have all played around with the idea.
 
for it to work as the opposite of a TC wouldn't it need to make the lens closer to the sensor? I suspect there is some optics in play as well as electronics.

Not sure if sticking a (albeit expensive) adapter with optics will ever improve picture clarity - it would increase FoV in the same way that a wide angle adapter on the ront of your lens would - dubious about the increase in exposure levels.


Aperture is the ratio of lens diameter to focal length - this adapter changes the field of view not focal length (that's determined by laws of physics) - clearly the diameter won' change and the focal length must increase by definition.

The only other way they could do it is by putting in a tiny black hole so that light is drawn into the lens - would cause quite bad distortion though I imagine.....

i think your just over complicating things, it just works :geek:
