Ok well this is screwed up.

The diagonal of the  220 camera with its  1/2.5" Type CCD is 7mm not 10mm.
I was looking at tube size perhaps.

So they did upgrade the size of their CCD as well is it's "resolution".
>From 7 to 9 mms.

So your normal lens for you 220 is a 7mm!
A little hard to miss your focus I think they're a prize they give out once
a year when someone misses their focus with this thing.




I'm remembering that bubble lens nikon made in the early 70s in which you'd
need to have your mirror locked up and you'd use a viewfinder to use it.
