recurring thread from days gone by now back again for one more go at it..
But check page 141 of Erwin?s Leica Lens Compendium (hard cover) he says
though the original design of the 24 was Minolta made with Minolta glass
other outside glass; the Leica version is made in Germany by Leica and I
think he is inferring so is the glass you?d have to read it yourself in his
words not mine as we know he hates to be misquoted.
This is 1974 folks. 2017 ? 1974 = 43 earth years.
This is one old lens. With digital computer design and new coatings
technology and glass designs they may as well have been wearing powdered
wigs.
Lens design technology keeps moving on as far as I go I?m only nostalgic
with my lens choice after I?m covered with the most cutting edge current
designs I can afford.
Then I buy for a song used old stuff for their inimitable optical
fingerprint and glow; in other words what they didn?t know then.
Personally when I want the look I get from my glass to stand out as
different then I get a lens newer than everybody?s not older.
And what makes it interesting is how sharp it is not it?s quaint defects.

In that era it wasn?t only zooms that were Minolta. The 24mm f2.8 R lens
was still the Minolta design up to the end of production, though again, I
believe built by Leica in a Leica quality mount.
