Maybe for such things like Nikon's VR-II technology, or maybe even their Nano Crystal Coating technology?
In some cases like the 11-18 lens from Tamron, there is little differences between the Minolta and Sony offerings IMO. So in some way it is the same, exact product.

As with gasoline, they can coat their own later.

I'm sure if the "Sony" falls off, it will work exactly like the Minolta-branded version. Minolta were never great but they were acceptable. I find their film scanners to be much more than their cameras ever were.
Canon makes own glass - link to lens tour
efoto, I thought you might enjoy this given your question earlier: From a thread awhile back - a tour of L lens production, from mixing the components for the glass to assembly.

You can click in at any point, but the glass making is - intuitively - upfront. From there you can click through the whole thing.
Here's the starting text:
Raw materials used to make optical glass
Creating optical glass requires the subtle manipulation of refractive index and other various optical characteristics.That is why more than 50 types of raw materials are utilized to achieve the optimum proportion and combination for each type of glass.

If he's constantly making ISO speed adjustments on every shot, it doesn't sound as though he knows how to use film SLRs at all. If he doesn't know to work within the limits, he's not a good one to be giving advice.
It's like he's saying "well, this one doesn't work the same way as the cameras I know, so it's no good."

That was pretty cool law guy, thanks for sharing that (again). Interesting to see all the steps that go into making the glass itself and a full lens. Almost makes me feel a better about spending so much on lenses now....almost.

Although he does seem to be very pro-Nikon, i think many of his arguments are valid. As for adjusting ISO, I'm no pro, but i think he's doing it cause he does live-action photos a lot. and when things go into shadowy areas, you're gonna have to up the ISO in order to maintain a high shutter speed. That's probly why he changes ISO a lot. and i think he's talking about D-SLRs, not film cameras.

It looks to me like Sony only bought the brand name. there is no "Zeiss" in sony lenes. I mean are they really even made in Germany? crtainly not.
Zeiss gained its reputation in the years that bordered World War II. Back in those days engeners did not use computers so the company with the smartest designers built the best stuff. Also they did not have computer controled machinning or modern plastics so they depened on the skill of craftmen to build the lens. I have one old Zeiss lens built in Germany in the early 1950's It's on an early 35mm SLR from the same eara (Before Nikon made a 35mm SLR) The lens is nice for it's day. maybe the best available and I'm told was horifically expensive when sold new in 1952 It's a 55mm f/1.4. I also have a 1970's vintage Nikon 50mm f/1.4 lens as well as a modern Nikon autofocus 50mm f/1.4 lens. Of the three the 70's version is without any doubt the best build quality and the new version has the same optical quuality but costs moch less (after figuring for inflation) and is much lighter too.) When the japaneese started copying the German designs in the 1960's that did a better job, I thnk. The Nikon F1 was better built then my Exacta/Zies post war vintage camera. (no I'm not that old, the Exacta was old when I bought it.) One more thing. Back in those days one bough a camera and a lens from diffent companies. There where several companys that made "exacta mount" optics. Zies being just one of them. Exacta did not make lenses. I think it was the Japanese companies that were the first to make both lens and cameras and this has been only for the last 40 years. Bot the reputation of these optics companies continues.

Yes, he's talking about digital cameras since it would have been ridiculous and counter-productive to change the ISO setting on anything but a whole roll of film. It doesn't seem as if he knows photography, just a few recent cameras, to read things like this.

Evidently you missed the mention of Zeiss lenses in the DPR preview. There will be three of them, a 16-80, 85/1.4, and a 135/1.8.

I remembered reading this too, particularly in recent years as I've watched Sony DV camcorders transition to Zeiss lenses. I had read in Usenet that Zeiss designs them, and Sony has them manufactured to those specifications. I decided to do some digging and found this:
Sony produces digital cameras of different types in extremely high numbers in several factories in Japan. The lenses for these cameras have to come from lens factories near the Sony camera manufacturing facilities to ensure reliable deliveries and minimize the economic risk of interrupted supplies.
ZEISS lenses for Sony digital cameras are developed by lens designers at the Carl Zeiss plant in Oberkochen, Germany. This includes all required quality assurance measures (test methods, test criteria, test devices, test procedures, lens performance target values, etc.) The lenses are then made in a lens production facility jointly chosen by Sony and Carl Zeiss. Quality assurance specialists from the Carl Zeiss plant in Oberkochen implement the ZEISS quality assurance system in the chosen facility. Many ZEISS optic measuring systems are installed. Carl Zeiss audits the lens production areas on a regular basis.
All these measures ensure that ZEISS lenses in Sony digital cameras meet the expectations demanding users associate with ZEISS lenses.
(from the ZEISS website FAQ, http://www.zeiss.de/C12567A8003B58B9?Open)
So, made in Japan, designed and approved by ZEISS. Are they true Zeiss lenses? Sounds like a semantics game.
(By the way, how do you pronounce ZEISS? Like Ice? Ace? Seuss?)

Say it like ice.
So, the lenses aren't made directly by Zeiss but have to go through the exact same processes? It sounds as if they should be worthy of the name, as long as Zeiss is randomly checking to see if there has been cheating. Still, it feels a bit like an Isuzu car running around with a Lotus badge because Lotus did some engineering work to fix the car's poor design.
