Originally posted by JohnBee Any idea how the Sigma compares to the DA* on the 300mm end of things?
I have looked at them extensively, and i purchase Bigma 50-500 with OS...
But the 100-300 seemed like the much better deal to me, the images were comparable and i actually seemed to prefer the images from the Sigma 100-300.
And the fact that the Pentax has SDM and costs a lot more, made me decide the 100-300 Sigma is on my shortlist for a faster slightly shorter lens for me, at some stage soon..
Check out the forums for reviews, and images from both, but the cost and IQ would sway me towards the Sigma. (Surprising considering the Pentax is a prime) The Weather Resistance of the Pentax is attractive however.
