The review is written in a mordant, highly ironic style.
K.R. is at least clear about what his demands are: "careful landscape and nature photography". It's no wonder that he recommends the ZM C Biogon 35/2.8 instead. For his intended usage, that lens would be far far better.
I have, however, seen some alluring landscapes taken with this lens, ones that did not emphasize corner-to-corner sharpness, but utilized the inherent qualities, good and bad, of the lens, to create mystery and beauty.
A really good review would examine the qualities of a lens, its specific combination of compromises (every lens has them), and suggest ways in which that group of compromises might be alternately limiting and/or enabling for creative vision.
The fact remains that in rangefinder-land, the CV 35/1.4 is a really unique combination of size, speed, value, and imperfections.
I used it for a year and didn't like it, especially because of the slightly cool and muddy colors, the distortion, the focus shift on digital, and the corner softness. YMMV.
