P3D brand new lenses

[tmd@xxxxxxxxxxx]

As I tinker with my new (old) stereo cameras, something has occured to me.
The cameras are far less complicated inside than I first imagined.  Which
makes me a little bolder. :^)  And the recent question about viewer optics
has spurred a question.

I'm wondering why more people don't just replace the lenses in their
cameras with brand new ones.  Couldn't an approximate match be found in
(gasp) Edmund or somewhere?  Is it a problem of matching the optics
exactly, or are modern lenses just not as good as the old ones.  Or maybe
it's just price?

Thanks,

Tom
