I agree JC, but then there's also a big part of they way things are
manufactured in our era. Sad, for sure but IMO selling lenses now for
DAs would be (speaking for me) more about selling F/FA/A which are not
that well on a build quality POV rather than selling e.g. my K30/2.8.
But selling my F35-70, F28/2.8... why not.
2007/2/11, J. C. O'Connell [EMAIL PROTECTED]:
I forgot to mention this on some of the earlier threads
concerning old vs new lenses. One of the reasons why
many of the early pentax lenses ( late screwmounts
and early K/M) mounts are so damn good is due to sample
to sample variations ( or lack thereof! ). Not only was the
build quality higher throughout the entire lens lineup,
but along with it came better MFG quality and quality
control. It doesnt matter if you have the worlds latest
and greatest optical designs if you cant build them
consistantly.
Does anybody remember the special feature the Honeywell
Pentax screwmount lenses had in this regard? ( this isnt
a question I need answered, this is a quiz to the listers!).

Pretty much all the 19-35 f3.5-4.5's are actually Cosina lenses.
Tokina, Tamron, Vivitar and several others all rebrand them.
Not a bad little performer, especially for the (extremely) low cost.

I remember that in 2000, when I was buying this lens, I looked at the
comparative review (tests) in Practical Photography (don't mix with
Popular Photography). The tests results were different enough to
warrant comments comparing the quality of these three. Was it just a
sample-to-sample variation, difference in quality control for
different brands, or what?
Igor
Sample variation, almost entirely.
