I'll second what TCav wrote. As I mentioned in my longer post earlier, the Pentax 55-300 lens is not macro rated. So if you want macro capability, I advise you go with the Tamron or Sigma. And, by the way, if you go for the Sigma, make sure the APO letters are in the lens name. There's is another 70-300mm Sigma lens out there that isn't as good.
And if you go for the Tamron, make sure the Di letters are in the lens name. There's is another 70-300mm Tamron lens out there that isn't as good.
