Klaus - reg. Pentax glass, just out of curiosity - is it really Pentax ot Tokina/Sigma rebranded lenses ?
Anyways, regarding the different systems, despite some awesome lenses by Oly or Pentax, etc., most of the market goes into the hands of Canon/Nikon and I think it's becouse those two systems are the most "complete" in terms of glass and ancilliaries, for any user irrelevantly of sensor size.. For me, FF format of the glass is just more of a future-proof investment and even when I owned 2 bodies (FF and DX) I decided to invest only in FF glass, weight and size issues didn't matter for me that much. Performance and a kind of future-proof purchase did <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

Pentax lenses are designed by Pentax ... within a handful of exceptions (18-200 (Tamron), 18-250 (Tamron)). Sigma has no ties with Pentax whatsoever. Tokina shares a few lenses. Sony is also using a the Tamron 18-200/250 base design. Nikon used a lens design from a japanese university I think (70-300). There're probably a couple of further funny ties under the hood.
As far as glass is concerned - I think most of the conventional glass comes from Hoya - and that includes the other brands (Nikon, Canon, Sony, Olympus).
FX vs DX - I think it is a phantom discussion. Most drive a Volkswagen-like car although everybody desires a Mercedes. Technically nobody needs a Mercedes (nor a Volkswagen actually). And even if you got a Mercedes you may drool around a Bugatti (equiv. medium format cameras). You have to find your sweet spot whereever it is. APS-C sensors are not without perspective. I reckon within 5 years APS-C sensors are as good as FF sensors today.
