Just learned from a wiki, that a 1 inch sensor actually refers to a vidicon tube of that size, a valve based technology, that only had a 16mm exposable surface.
Thus a 1/2 inch sensor is only 8mm coverage!
So a 1/3 lens may not cover the Pentax Q system at all. _________________ ---------------------------------
