I've been using the Tamron 70-300 LD Di as an interim lens, but recently had the opportunity to try the DA 55-300 and found it better

The improvements were enough for me to to buy the Pentax in the meantime and sell on the Tamron.
Good to hear the first-hand account. I'd like to see how it compares to the old FA J 75-300 out of curiosity.

I confess to similar thoughts, especially if I wind up with the 55-300!
Quote: I keep thinking that the Bigma would be a good choice for what I want, but I'm put off by the size/weight and the small max apertures at even moderate focal lengths (it shuts down quite quickly), plus I've never been lucky with Sigmas, though I must say I've been quite impressed by many shots I've seen from other users.
I've used a Bigma, and you're spot on. It's a big, heavy, clunky beast and it needs a lot of light. The fact that wildlife is typically more active in the morning or evening simply exacerbates its flaws. I've seen some excellent shots with it as well, but I was not able to reproduce that quality. The reach sure was nice, though.
It would be more favorable to me if a lens like the Bigma would sacrifice about 200mm on the short end and run from 200 or 300 to 500 or even 600 in order to shed some weight and size. My uses for a lens like that, especially with mid zoom options like the DA*300 and the 60-250, would be pinned at the long end most of the time.
