Hi, I bought the FA* 80-200/2.8 a couple of weeks ago. So far I am very pleased with it and an I can second everything John Francis said about this lens. Also, if this is important for you, I think it is one of the very few zoom lenses that have a good bokeh. That was the ultimate reason why I preferred it over the Sigma (which also seems to be a good lens).
For the size/weight/flimsy tripod mount issues: They all (2.8 tele zooms) are heavy and bulky; IMO the Sigma is only marginally lighter. If weight is an issue I would not go for a 2.8 zoom at all. (BTW the dimensions of the Pentax FA* are almost identical to those of the Canon 70-200/2.8L). The Pentax FA* is mostly made of metal (including the tripod mount, which is certainly not "flimsy") Some other aspects which may be of interest: The Sigma APO EX 1.4x converter fits the FA*80-200mm though it is not mentioned under the list of compatible lenses manual of the converter. But actually it fits because its "snout" is shorter than that of the genuine Pentax 1.4L converter (and designed for A* and FA* tele lenses) that will *not* fit (only the Pentax S-converters fit). But this one does not allow autofocus anyway. The Pentax focuses down to 1.4 m (vs. 1.8 for the Sigma) and the tripod collar (of the Pentax) is removable so it does not get in the way when shooting free-hand. Enjoy, Alexander I was in a similar situation choosing between the Sigma and the Pentax.
