[Leica] 4/3's lens firmware updates

[r.s.taylor at comcast.net (Richard Taylor)]

This really *is* NASA-stuff.  The lenses in our Infrared Array Camera  
on Spitzer are simple doublets.  They are corrected in the initial  
software processing pipeline for geometric distortion and other  
aberrations to allow for precise matrixing and photometric accuracy.

Regards,

Dick
