I've never before this review of the lens remembered the contrast or
resolution of a Leicas lens described "medium" let along "low".
I think in glass made in the 1930's the word "medium" was used now and then.

I'm surprised no one could fish out his or her Erwin book or look up the PDF

>From Erwin's LLC on my hard drive, as simple search for the word 'medium"
reveals:

"in fact the Noctilux 1:1/50mm has low medium overall contrast "

"The Summicron-R (I) has better overall performance than the Summicron (II)
for the rangefinder system: generally we note a higher contrast in the
field and a much better reduced level of flare. At full aperture we note a
medium to high overall contrast"

"At full aperture the new Summilux-R exhibits medium to close-to-high
contrast"

"15mm Super-Elmar-R ... At full aperture overall contrast is medium..."

"19mm Elmarit-R ... At full aperture contrast is low to medium"

"28 Elmarit-R .... It is of comparable performance of the contemporary M-28
... At full aperture we have low to medium overall contrast"

"The PC-28 at full aperture has medium contrast"

"The Summilux-R for the 35mm focal length ... At full aperture overall
contrast is medium"

"1.4/75, Summilux-M, 1980 & 1.4/80, Summilux-R, 1980 ... At full aperture,
overall contrast is medium ..."

"2/90, Summicron-R ... At full aperture contrast is low to medium"

"4.8/350,Telyt-R ... Closely related to the 4/250 (2), this lens exhibits
essentially the same character, but with a generally lower contrast. At
full aperture contrast is low to medium"

And there are numerous others.
