Cool thanks Ira!

Now I'm assuming the difference between sigma's 7-300 APO and the old pentax 100-300 f/4.7-5.8 is quite substantial, but I don't like the overlap in lenses with the 125 with the macro lens - which leads in to - what is the pentax like for macro - i know it is not designed for macro, but does it get really close otherwise? I might end up getting the Sigma because of the macro option and it is quite cheap.

Sigma 70-300mm effectively a 105-450mm, Pentax 100-300mm effectively a 150-450, not a great deal of difference. Either would make a good partner for the Sigma 18-125mm. The Sigma 70/75-300mmis a macro I believe so it will get closer than the Pentax.

This image was taken at the closest focus distance at 300mm with the Pentax:

Not bad but not a macro.

Yes, the Sigma 70-300 is a Macro Lense Between 200MM and 300MM.
