RE: Eclair ACL c-mount v. nikon mount

Hi, there!

Now perhaps we can have a frank discussion about zoom lenses and zoom lenses
and zoom lenses vs. primes. I've shot with the Angenieux 12-120 many times,
and sometimes I've had good results and other times I've gotten soft
results, especially in freezing temperatures, at low light levels and at
wide open 12mm. In bright sunlight, shooting at f/11 and smaller I've gotten
very sharp results. I've had better luck with Schneiders, such as the
10-25-50mm lenses on the Arri S for example. With respect to the Cookes,
I've seen good results, both color and sharpness, in 35mm. But the Angenieux
25-250 zoom lens has been good in 35mm as well. I think it's a terribly
underrated zoom lens. I've shot standard Zeiss lenses on two feature film
with the BL III, and the results were sharp pictures.

They are in most peoples opinions the best lenses that have ever been

I went to the factory some years ago & can vouch for the fact that

In connection with that, the late Ken Richter (Richter Cine Equip.,
auto collimator, EMP camera) told a story about Cooke.  Years ago, BC
(before computers) he would on occasion visit a friend who was a lens
designer at Cooke.  If I recall the story correctly, on one occasion
Ken told me he had a suggestion for an improvement on a lens design
and suggested it to the designer.  The designer thought about it a
minute, wrote something on a piece of paper, then stepped briefly into
a nearby room.  A few minutes later someone came out of the room and
handed him a note.  He read it and told Ken that the idea might be
possible.  Ken, curious about what was in this other room, asked to
look in.  Inside were a number of desks with school boys seated,
working out mathmatical equations for the lens designers.  These young
geniuses were Cooke's "computers"!  I think this would have been in
the late '40s, early '50s.

Les, did you ever hear this?
