We had a Konica Minolta colour copier in our main office at work and in another office there was a Kyocera copier which if I remember rightly was the company who made Yashica and Contax cameras and lenses. Some of he Contax Zeiss lenses were made by Yashica. Yashica had a very good reputation for making excellent lenses both for Yashica and Contax and they quite often out performed the Canon and Nikon equivalents.
I met the Tamron rep in my local photo dealer last year and managed to have a good chat. Its seems from what he was saying indicated that Tamron makes most [but not all] of the Sony Ziess zoom lenses to a Ziess specification but he was unclear as to how many assembly plants were involved, and he said their own 17-50 and Sony 16-50 shared many componants and design, and he said Tamron were involved in the Zeiss Vario Sonnar 16-80, but would not elaborate but said Tamron were not involved in all Sony/Zeiss lenses, there were other players as well. He also said that Tamron had more experience at making zoom lenses for 35-mm and digital cameras than Zeiss did.
Its a bit of a mystery these days to even track down who makes what and for whom. Some of the Sony lenses are made by Tamron, but i'm sure they are not the only source. The Tamron rep did mention Sigma and Tokina as two other companies who were supplying the 're badged trade' along with Hoya.
I don't think Sony themselves will ever disclose their lens sources.
I think launching a new and expensive lens to a small market from any of the manufacturers is a risky busines these days especially because of the world economy in recession.
Of course classiccameras, I was forgetting the input from Tamron thanks for the reminder, they were involved with KM B.S. (Before Sony), to some extent but I’m not sure how big their influence was, personally I don’t think representatives are necessarily privy to information that’s more accurate than we can find (not much) apart from what they hear on their own rumour mill, and that could be worthwhile or it could be sus, how can one tell?
I know a couple of lenses back in KM days that were obviously of Tamron origin, the 28-75/2.8, 17-35/2.8-4 stand out because they don’t have the Minolta focus range window and the focus collar revolves backwards (a la Nikon) and I think the KM7D had a kit lens from Tokina when it appeared, at least it did here, but by then KM was involved heavily in negotiations with Sony where it would all sone become KM A.S. (After Sony).
I think the KM optical div was making a few Minolta designed lenses for Sony for an unknown period of time after that, the 16 was one, the expensive 35, the 50 & 100 macros, the STF, the standard 50, the 70-200G and the 500reflex. They also had the KM24-105 and the 18-200(Tamron design, but who was making it?).
They didn’t bring over the 100-300APO(D) strangely enough even though the design was completely updated at that time, it was to be a long long time before Sony finally brought out their own 70-300G(origin unknown), and much later the 70-400G(origin unknown).
Sony announced the 16-80 Zeiss way back when the A100 came out (along with the 135 & 85 Zeiss) but the 16-80 had a lengthy delay period and when it was finally released it was plagued by problems that seemed to go on forever, definitely no KM involvement with that one, and I don’t know who was doing what with the 85 and 135 Zeiss either.
They since have brought out a whole bunch of APS-C zooms, some seemingly duplicating or overlapping ranges already covered by other lenses of similar speed, and I don’t think KM was involved in many or any of those.
Then there is the SAM lenses, maybe Sigma is involved with the optics for those and some of the zooms as well who knows? Tamron could be assembling some of the other zooms too, like you say it is all very mysterious and convoluted, I wouldn’t mind betting there is some involvement by the Chinese in making lens barrel components.
Who is making the 300/2.8G and the new 500/4G for Sony? I see Sony has a 300/2.8G II out now too.
Sony don’t seem interested in any f4 lenses as far as I can tell, there isn’t any 24-105/4 or a 70-210/4 in the range.
