Image Circle Sizes for a few NX Lenses

@viking79: thanks very much for sharing your findings. Confirms what we suspected.

@UzminiNu: Yes, I'd love to believe the FF rumour. However it does seem a little unlikely, doesn't it.

BTW, the only way this large-sensor rumour would make any sense at all would possibly involve a circa 1.3 crop (a la Canon APS-H) sensor. But APS-H is an orphan size, so scratch that idea
