Hi all!
After a quite long break on the forum (too busy with my job and above that need to spend more time using my lenses instead of spending my time on Internet/forums  ).....Anyway, I would like to share now some pictures made with this great oldy lens, a Cooke anastigmat 4.5/5 inch.  ...The lens has no helicoid of course but has a barel with a beautiful round iris, such a beauty lens! I bought this lens at the camera fair in Houten for 35€, quite a good price I guess and the lens is not only nice but seems to be also a very good performer, at least for my use ....
I did not yet found a solution to properly adapted the lens so until now, it is just attached with some tape on the bellows, not so nice to see but at least it works!
Ok, here are my first samples with this lens, all are wide open, without any PP (except #9&13, curve&levels adjusted ), and without any contrast and sharpness added.......(you can click on pictures for higher resolution......)
1/at first a picture of the lens:

7/
8/
9/
10/
11/
12/
13/
14/
15/
and a 100% crop from my cat!:
That's it for today ....
I don't have so much knowledge about optics but I would like to know more about this lens, for exemple how can I know how old is the lens (serial number is: 88640)? I suppose that the lens is uncoated? I'm pretty sure some members on this forum could provides more informations about this lens  .....Anyway I'm verry happy with this lens, it's a lot of fun to use and it's for sure a real good performer....
Thanks for looking and all your C&C are Welcom of course  ...

Welcome back!!
Cooke Triplets wrote the history of photography!!
And you put yours to a great use.
I have some years experience with manual photography, so I shouldn't be surprised,
yet, every time I keep being amazed at how these dinosaur lenses can produce still such great images today!

Thanks orio ...
Well, I didn't know that Cooke Triplets wrote the history of photography, so it makes me also a very proud "owner" of this legende ....
What surprise me a lot is that this "simple" triplet lens was supposed to be not so contrasty (according with what I could read on the Net!) but when I look to the pictures, it doesn't seems to be a problem at all!.....

Actually, "net people" are ignorant  so don't trust them
Loss of contrast (and of luminosity) in old lenses is due to the number of glass-air surfaces. Lenses with 4,5,6 glass elements are those that lose the most
of image contrast. This is the reason why Planar lenses (which usually require 6 single elements and therefore have a high number of glass-air surfaces)
were not commercially exploitable until the introduction of lens coating sometimes around 1940.
Of the old lenses, triplets and doublets (duplets?) are those who retain the better contrast, because they have less glass-air surfaces.
Of course if you shoot them straight into the sun they won't be happy anyway

Well may be you're right, but pictures #6,9 & 13 were shoot straight into the sun and I found the results not so bad for an uncoated lens!
