I should have clarified that the only point of interest in that article were 
the sample images of the plant at 0, +2, -2 on the SA dial. They are best 
viewed full screen.  I didn't pay any attention to the rest of the article. My 
main interest in this lens is the effect of the SA control.

Perhaps a more descriptive review is 
Which explains the SA control . Maybe common knowledge, for me educational, 
view #6 explains how the spherical aberration effect varies with subject 
distance and magnification.

More sample images of SA control here:

Besides the fiddly nature of vintage lenses, many have a MFD that is generally 
not close enough for my interest. It seems range finder cameras set 1m as a 
standard MFD. If a modern lens can create the effect, it has my interest. 
Vintage lenses are too much of a crap shoot for me.

As you say, most of them stay at your house, rarely out in the field as 
"serendipity" with such lenses is the use case. Hence the Canon, with SA 
control, is a very useful, away from home, predictable option, where you have a 
great useful lens, that adds an effect if you so choose. I'm not trying to sell 
the lens, just that it has way more interest to me than the vintage approach.

some nice photography.

Can one have too many macro lenses?
