35 asp canada ist series

[tim_robinson]

I use one of these from time to time and want to know how it

compares to the new one.

[roberto_watson_garc_a]

are you talking about the first 35/1.4 asph, with two aspherics

elements

[tim_robinson]

The one that was made in about 1989 ish. The aspheric

elaments were ground in canada and when production moved to

Europe the machine could not get the same tolerances.Leitz

then took this lens off the market and looked into molded asp

elements like Cannon had done.I think this info is about right.

Tim,

 

<p>

 

There were not too many of the first version of this lens out in the

real shooter's world, I've read that the target was for 2000 lenses.

As far as comparisons to the second version, I looked in the new book

from Erwin Puts on Leica lenses and found the following:

Regarding the ASPH (2nd) version, Quote "... Generally this lens

performs in an identical way as the "aspherical" (1st) version.

there are a few subtle differences: the ASPH version has slightly

lower contrast on axis, but more even performance in the field at

apertures f/1.4 and f/2.0. From f/2.8 both are equal in image

quality. Vignetting is slightly higher..., and distortion is visible.

"The fingerprint differences are really very small, if measurable and

I would not be put to the test to identify which lens is used when

presented with some pictures." -Unquote.

I hope this information is helpful.

Tim,

I have a friend who had both lenses and compared the 2 and said that

he could find no difference when comparing chromes side by side. He

ended up selling the 2nd version and keeping the first. That lens is

quite collectable and from what I've seen very pricey.
