I am very interested in the history of sigma lenses. I searched the internet for detailed information: which lens was made in which year. I could not find this information. Even on the official websites of sigma, that information is not available in detail.
Therefore my question for links from websites that show the detailed lens history of sigma.
Who can help me with links.
Greetings pinkf |

Thanks for sharing the interesting information. I don't have a link to the original source either, but member Pancolart wrote that the chart came from ksmt.com :
http://forum.mflenses.com/sigma-ys-system-focusing-lenses-t38337.html
And I wonder how accurate the data are? The chart states that the XQ 135mm f/1.8 has 4 elements in 4 groups. But my own copy of that lens has 6 elements in 4 groups. |

55, I've seen somewhere that the XQ and YS differ. The one is a 4/4 the other 6/4. I have to search a bit. I do have the YS.

At your service, Phalbert.
Actually, it was a couple years ago when I disassembled my XQ 135 f/1.8 for cleaning. It has 4 groups and 6 elements. The second group has 3 elements cemented together.
There were multiple iterations of the Sigma 135 f1.8, so there certainly could have been differing optical layouts. But both my YS and XQ 1.8s have the same 4/6 scheme.
Here's my XQ:

That's quite interesting. I have a copy of this in either YS or XQ series, I forget which. I have never disassembled it.
The Sigma XQ series brochure posted here http://forum.mflenses.com/sigma-xq-lenses-t73290.html seems to show a 5/6 scheme, but in the accompanying text refers to it as having a 4/6 scheme. Possibly this is the brochure most other internet references were based on, and the mistake has spread from there. It would be interesting to see if anyone has disassembled a 5/6 version.
edit - this lens may assume a higher level of favouritism with myself now (for no good reason), I'm a sucker for a cemented triplet. |

Excellent work! Lens brochure may contain some false information which will become widespread.

I looked at my copy once I got home today. It is an XQ version, but still with YS mount. My copy has the triple cemented element. I wonder if they can be found in the 5/6 version too, and whether that version was later or earlier than the 4/6 one. |

Yes, I do enjoy tinkering with lenses. And you're so right, Phalbert. Sigma created a wonderfully simple and logical design for that 135. It's one of the easier lenses I've had the pleasure to work on.
If pixel peeping, my XQ is soft with some glow wide open. And its rendering has more "character" than my other fast 135s.
And that's a good thing! I wouldn't want all my lenses to be "perfect"! 
If you'd like to see for yourself, here's a brief comparison of an Azalea:
https://www.flickr.com/photos/158740233@N04/albums/72157718559923100/with/51083146122/
Right. I've also wondered about that.

Thank you. But I'm sorry for sidetracking your topic, pinkf. I blame Phalbert for leading me astray.
Regarding Sigma history, all I can do is point you toward Sigma literature. In addition to the XQ brochure Alun Thomas linked to, there's a 1980s brochure here:
https://www.cameramanuals.org/booklets/sigma_lens_booklet.pdf
And here are scans from a 1977 brochure I own:
#1
#2
#3
#4
#5
#6
#7
#8
Unfortunately, Sigma didn't include data for the 135mm f/1.8 in their specifications table.  |

Very precious information. Somehow the 100mm f/2.8 macro (if my memory is correct) is not included either. The lens is from the same series. The particular copy I got has hazy element. |

The XQ were supposed of better optical quality (Xetra Quality)
The ys are the standard version with interchangeable mount
