Hi Tan, It's also been my understanding that several (maybe quite a few) Pentax lenses are just rebadged Tamron or Tokina glass. I have also heard that Minolta (I knew this) and SIGMA! have produced lenses for Leica. I don't know the degree of Sigmas involvement, whether they just produced the lenses or produced them to very specific Leica standards or design. IAC, these days it's sometimes hard to know just what you're buying, and maybe it's no longer important ... maybe it never was. After all, when it comes to lenses, it's the finished product, the photograph, that really matters.
However, Tanya, I do believe that, overall, build quality and optical quality have taken a dive when it comes to many of the lenses out there. Only when you are paying for the high end glass are you reasonably sure you're getting good quality on both fronts. Another thing to consider is that when people tell you a lens is great, or poor, or sharp, be cautious. Descriptive terms are very subjective. Whenever possible try the lenses yourself to be sure they meet YOUR standards. Not only are subjective descriptions suspect to some degree, there are also sometimes wide variations in sample quality. So, while everyone swears the XYZ 15 - 500mm zoom is a jewel, you may be the lucky one to get a clunker. With digital cameras you have an option that's pretty easy compared to film users. You can walk into a shop, ask to see any number of XYZ 15 -500mm zooms, and try 'em all out on the spot, stick your card into your portable computer, and look at the results immediately, giving you a chance to choose the best one. Anyway, that's my kvetch for today.
