There was no reason at all for any change of design seen from the point of optical quality (sigh). (The lines above tell a personal sight only of highly complex facts. Never would any manufacturer issue an official statement like this. It's only fiction out of my small personal brain ...) I'm happy to have an old ASPHERICAL - and I wouldn't trade it for anything else. I didn't do any A-B comparison but a close friend of mine did and told me that there was definitely no improvement seen from the point of optical quality. The old one is the superior lens (better colors, more intermediate colors, ...). But the moulding process is far cheaper seen from the point of the manufacturer, however. (sigh again). Also there were only some 2000 pieces made of the old design, the lens was practically not available (you needed "to know somebody at leica"). The new model can be bought by far more simply and surely is a good lens, superior to the other 35 mm M lenses. Therefore (as the old model practicaly isn't available) there is not much use in building up a myth about it. But: If you can get hold of such a beast - go for it! Have a nice day all of you and please don't tell me too often that the new design is far better than the old one (it'ssimply not true).
