Ed -
Don't confuse blur with glow; Blur is just an unsharp picture while
the "Leica Glow" refers to the emphasis on the contrast and clarity
of the in focus area compared to the out of focus one.
Both Marc Small & G.Rogliatti have explained this in detail.
It pertains to an effect like a good quality diffusion disk can give
and not to unsharpness per se.
It lends itself particularily to b&w photography & is not popular
today with the majority of us shooting color. In the past, disks
silk hose, window screens & even vaseline on glass have been
tried to capture this effect. Some diffusion disks come close
but it is the quality of the uncorrected Leitz glass that gave this
effect and Zeiss & other lens makers called it a "cheap trick"
because it was taking advantage of the excessive coma and
other aberations of the E.L.W. glass.
So Ed - if one cant recognize this or see this quality in the
old Leica pictures (pre-color) then certainly one doesnt need it.

It used to be that we got that certain look when we didn't want it.
Now that we want it, just go back to the old-time lenses. The most
famous one (with the "look") is the 50mm f/2 Summar. It's uncoated and
usually always much scratched. Use that near wide-open and I
guarantee a wonderful soft look. Uncoated 50mm Elmars are too
good. Forget them. I once had a 90mm f/4 uncoated Elmar with
the "look". In the older days we got rid of those lenses as soon
as we could afford the "good" ones. Ed Meyers
