You can replace the lenses in the Life-Like viewer with Revere/
Wollensak achromats (which I have for sale) to result in a nice
achromatic viewer.

The Life-Like's lenses are actually smaller and of longer FL than
the Kodaslide viewer (the diameter is 20 mm vs. 25 mm for the
Kodaslide).  The slightly longer FL and the different design (simple 
one element vs. achromatic) might have something to do with Steve's 
observation.

I really don't see how this feature speeds up the viewing process.
Pressing the button with the same hand which holds the viewer is
an automatic reaction.
