There are also newer lenses, post K/M that exhibit CA when used on
digital, are these also obsolete?

We went thru this before. The defintion
of obsolete as I recall it when discussed
is way too vague. Just because an item doesn't
have some later feature doesn't make it
obsolete IMHO because that's like saying
if your current car isnt a hybrid its obsolete
because it doesn't have hybrid feature that
came out later. Or even worse, if the feature
that came out later is of little use like
saying Pentax POWER ZOOM bodies made all those
before it obsolete. Yeah right!
GET IT?
Obsolete: 1 a : no longer in use or no longer useful
b : of a kind or style no longer current
So, what makes a lens no longer useful?
I have older K/M lenses that show too much CA to be usable on digital.
For digital, those lenses are obsolete.
I have older K/M lenses that do not offer auto focus or programmed
exposure capability.
My needs now include AF and programmed exposure for what I use digital
for, ergo those lenses are obsolete.
Definition B needs no explanation when applied to the 25-30 year old
equipment in question.
Or perhaps it does.
Of course, you can say Merriam-Webster doesn't know the true
definition of the word, but I'd laugh and call you stupid if you did.
