Google a bit and see what users think of Sigma lenses labeled APO.
My APO version of that lens has never shown any signs of CA or PF. The same can certainly not be said of the Tamron (it can get pretty bad). The Pentax 55-300 is a lot better than the Tamron, but still not quite as good in that regard as the Sigma. But the Pentax does seem to edge out the Sigma in sharpness and certainly in zoom range. I do have a non APO version of the Sigma but have not tested it to see how the CA and PF is on it.

Well, so far it's thumbs up here. Just shooting around the house I'm very pleased with my purchase though I haven't had a chance to take it outside for nature shots yet. I'd say I definitely got my $$$ worth.

That Sigma 70-300 is a very ordinary lens which will disappoint you, had one myself a while back but replaced it with the Pentax 55-300 which my dear lady has since claimed as her own. While the focal range is quite convenient I'd suggest being patient and wait till you can afford the DA 55-300.

On the other hand, you might find that simply cropping images from your 50-200 will produce resuls as good as using any 70-300.

The only thing I really care about is the 300mm, with IQ/softness being not that important.
If IQ is not important, then you might as well just get the least expensive lens you can find. But if you want to get the most bang for your buck, the best option is probably the FA 100-300/4.7-5.8. I recently bought a version from keh for $80. While the lens does not have great resolution at 300mm (cheap telephoto zooms never do), it has good contrast and very good color rendition (not that far behind the DA* 300). Many of the cheap telephoto zooms not only lose resolution at the long end, but contrast and color as well, leading to soft, flat, uninspiring images. That, at least, is not an issue with FA 100-300/4.7-5.8
