Subject: [Leica] My comments on the Lux 35 discussion

Thank all of you for your insights on this product.  Even more thank 
yous to the people who could show example pictures before ragging on it 
in favor of the ASPH.  The following are my comments.

1.	The people who like this lens tend to be the same ones who shoot at 
night or in frontlit conditions.  The people who favor the ASPH lens 
point to pictures where the camera is pointing into the light source.  
It is my understanding (and has been since I was about 11) that you are 
not supposed to shoot into the light with anything.  The person who told 
me this must have been using a 35/1.4.

2.	In Rei's picture, the ASPH definitely has an edge - but it still 
has a ton of flare under those conditions.  I would guess that a 35/1.4 
is on the margin of what can be done with optics.  Having the 
aspherical  elements and more glass in a barrel tends to improve 
things... a little.  But I have several 1.4 and 1.2 lenses (not 35mm) 
that don't quite whiteout  like that when pointed into the light.

3.	Somebody (Colen?) mentioned that higher contrast is better.  I 
don't think that's the case where you are using superspeed lenses from 
the 50s and 60s --- the Canon 50/1.2 LTM is pretty flat wide-open in 
sunlight but in dark environments with harsh, low indoor light, it is 
fantastic.  No matter how bad a lens has been alleged to be, I have 
never seen a drop in contrast such  that jacking the printing contrast 
up a grade hasn't solved the problem.

4.	I like what I am seeing, that the Lux has the right type of bleed - 
there isn't really a name for it, but the 50 Sonnars, Canon 1.2 and the 
Helios 85/1.5 all have it:

It's not the flat precision of an uncoated Summar or an undercorrected 
Summarit; it's the glowing edges where local flare makes the highlights 
sparkle and undercorrection annihilates  what lies outside the plane of 
focus.

5.	Any lens they made for 35 years can't be all bad.

So when does that damn thing get here?!
