Very interesting design, and the price signals this glass monster should never be used to do real photography for the fear of scratching the lens :)

The calculation to show this is an "f/2" lens was just stupid, though.

Maybe free shipping can be negotiated?

I think they took the x0.51 factor into calculation of the focal length as well.

I thought the same way.   ;D

Petapixel later issued a "correction" explaining that the Leica Store Netherlands had written the stupid copy.

Rare Nikon glass becomes even rarer when transformed for cine or astro use...2,0/300 IF-ED or 2,8/6 Fisheye are really unique ! Thanks Akira for this article  ;)

my thought is they missed the square root.  so for a image diagonal ratio of 0.51, (0.51)^1/2=0.7141, 0.7141x4=2.8566

I would like to know how to properly scale aperture as I have been using the Fuji GFX, so if I have this wrong let me know.

There is no need to "scale" aperture. It stays put whatever the format. The same holds for image magnification. And image circle. And the angle of view of the design. And resolution.

What does change with the format is how much of what the lens "sees" that can be recorded onto film/digital sensor.
