Re: Do you want a 10.5mm f2 prime?

There is a Nikon FX lens AF-S 20mm f/1.8. Size is 82 x 84 mm, weight 355 g.

Scaling this down in every dimension by a factor of 2 gives a lens of size 41 x 42 mm, and if all components would be similarly made smaller, the weight would be 44 g (1/8th). Of course, realistically, the lens would be heavier, probably over 100 g, similarly to the 12mm f/2.0 Olympus (size 43 x 56 mm), which is 130 g.
