One of favorite lenses! Sharp throughout the focal length range. Fast fixed aperture, even better using the TCs.
Reach the 35mm equivalent of 900mm with the 2X TC. (Dedicated TCs cannot be stacked)
In bright sunlight you can still AF with the 2.0X, even though Sigma states that you have to use Manual Focus with the 2.0X TC.
Even if you use Manual Focus, you still get focus indication in the finder with a focus tone in the camera. Great thing about Pentax.
The TCs can also be used with the Sigma 180mm f/3.5 Macro Lens.
See my listing here for the 180mm Macro:
