Canon FD 35/2 chrome nose question

Hi,

I bought a Canon FD chrome nose 35/2 again today. So I have two of these with the new one in much better condition. The old one s/n is 10756 and today's lens s/n is 21864, and both have concave front element. I felt the new one is heavy and then measured them. The new one is 100 grams heavier! The chrome ring did not go out when focusing and its rubber focusing grip is a little nerrower. I will post images to show you what I mean. I am not sure if this has been discussed before. Your input will be appreciated.

Cheers,

Zhang

There are, in fact, three known variants of the FD 2/35mm chrome nose.

1) SN 10001-12199 (chrome nose moves outward when focusing!)
2) SN 12200-20000
3) SN 20000-50000 (in this range we have both chome nose and black)


Obviously, version 1 and version 2 have different mechanics; I didn't know that their weight isn't the same, though!

Different mechanics or no, is the optical formula the same for all the breechlock 35mm f/2 lenses? It sounds like v1 and v2 may be different?

usually, a later version of the same lens is lighter. But the case for FD 35/2 is strange.100 grames for a lens like this is a big portion.

Canon's documentation says it weighs 420g, but mine is 508g (SN 25352). So almost 90g heavier, that is a bit unusual.
Canon does not mention anything about this weight difference.

Interesting to compare the likely unit count vs say Nikon.
The Nikon equivalent 35/2 lens (to 1981) seems to have over 300,000 units made, 4x Canon.

A good indicator of how much ground Nikon has lost to Canon since the 1980s.

Is there perhaps a version 4?
Mine has serial number 55527 - black nose of course.

I did a search on the internet, and by weight, there are at least 4 versions:

"Brief Specification for Canon 35mm f/2.0 early version.:- Optical Construction: 9 elements in 8 groups No. of Diaphragm Blades:- 8 Minimum Aperture:- 16; Closest Focusing Distance (m) 0.3 Maximum Magnifcation:- 0.194X Filter attachment size:- 55mm Maximum Diameter x Length:- 64mm x 60mm; :- 420g (67mm x 60mm; :- 370g - S.S.C. version)

Focusing: Helicoid Minimum aperture: f/22 .A
Diaphragm: Automatic Filter Size. 52mmHood: BW-52A Cap: C-52
Function: Auto Aperture, Full aperture metering (AE operation when used with ALL Canon automatic SLR cameras.
Length x max. diameter: 46mm x 63mm
Weight: 245g"

Now we have 508 grams.

Hmm, I didn't realize that the chrome nose had more versions, I have the SSC concave, and always wanted an chrome nose 35/2 too go with the other chrome nose lenses I have.

I weighed mine without both caps, the 1st version is 410g, and sn 21864 is 510g.Their sizes are not the same, SN 10756 is 64mm, SN 21864 is 67mm. The rubber grip size is 19mm vs 22mm (10756).

I also have other chrome nose lenses. My SN 21025 FD 50/1.4's chrome ring goes out when focusing to reveal its true face.I would like to collect a few more chrome nose lenses as these have a more solid feel.
