Cooke Speed Panchro Lens 75mm f/2, T/2.3

After the tests I gave back cine zoom lenses from Zeiss Arriflex SR16 10-100mm and Som Berthiot's 35mm Pan Cinor 38-150mm. Both had scratches. Then I found Cooke Speed Panchro Lens 75mm f/2, T/2.3 that is converted to M42 mount and with an adapter perfectly fits to Nikon F. Have a look below the lens and one shortly done test.

Hi,

Is the glass very yellow?

It is more yellow than the glass from other lenses. I read that could be possible because of the coating process the lens is radioactive?!

Quote: (Stephen Williams)>>"75mm one's are always very yellow as the coatings were radioactive and have changed over time."

Like one or two Nikkors!? Hopefully not. Have a look at the picture below.

Hi,

The 75mm Cooke usually suffers from radioactice decay. Nothing to worry about. A very nice beauty lens IMHO.

Thanks Stephen,

also I found googling online the following text:

[Wolfgang Rabe from Germany just wrote me: "you wrote in the description of the Taylor&Hobson lens that the glass seams to be yellow. The reason is that the lens is made with lanthanium glass, it is lithly radioactive and this colors the lens cement to yellow. It is not so good for color but perfect for B&W"]

Hi,

With color grading the yellow is no issue at all. The Older Cooke SII/III lenses were used for the close ups in Mr & Mrs Smith. Cooke S4 were used for the rest of the photography.

Thanks Stephen,

Great!

Cooke Speed Panchro Lens 75mm f/2, T/2.3 is SER II.

I am happy now and waiting for a good weather here in Vienna to do some video tests with Cooke+FX1+M2 35mm adapter kit.

Hi Stephen,

Tell me, since the panchros were made before color film became the norm... pretty much, will this affect their performances overall?
