RE: [Leica] 35 Summicrons

[Buzz Hausner <Buzz@marianmanor.org>]

The "spherical" 35 Summicron is a good deal shorter and a tad lighter than
it's aspherical sister.  I also recommend buying either lens in its black,
aluminum barrel expression, which is lighter yet and less costly than the
brass-barreled silver finish.  There are a bunch of books and perhaps web
sites (Irwin's?) which give the particulars, but I find that an M6 with the
spherical version mounted slips into my jacket pocket while with the
aspherical mounted it does not.  I also use the 12585 vented shade in place
of the square shade supplied with either lens.

I too am trying to decide on a 35mm lens. As I cannot find any specs on the
pre-asph, you can tell me why is it more portable than the Summicron asph
which weighs in at 255 grams with a 39mm filter and 34.5mm long? That seems
very portable to me.

On the other hand, if your optimization function includes a kit which can be
carried in one's pocket you can't beat the pre-aspheric.  I own both and
prefer the pre-aspheric because of its portability in addition to its
wonderful image quality which I freely admit isn't up to the micro hoo-ha of
the aspheric.  It all depends upon what you, the individual photographer,
wants in her or his gear.

IME, the ASPH is substantially sharper than the non-asph at 2.0, noticeably
sharper at 2.8, and a bit sharper at 4.0.  At 2.0 and 2.8 it maintains its
center sharpness way out toward the corners, and has a higher macro-contrast
at these apertures as well.  I think it has less flare than the older lens,
too.  Erwin says it has less field curvature, but I've never noticed this -
I'll take his word for it (I don't test lenses, I just use 'em).  I think
Erwin's report is accurate, but for my photographic tastes he understates
the improvements in the ASPH.
