The AF speed on the Sport can be changed; I believe there are 3 settings and I would assume that is comes set to "middle of the road". Whether Sigma have given the same functionality to the Contemporary I can't work out

All these AF speed settings are a trade off, if you set to 'speed' you could lose accuracy and if you set to 'Focus' then you could lose speed, the mid point 'standard' is a trade off between the two. If there was one setting that gives you the fastest AF speed and most accuracy then that would be the only one needed. It is up to the individual to choose what best suits him or the situation.
Here are the three OS settings from the Sigma manual. Not sure I really understand the differences though.I have read elsewhere that there are 3 settings available for the Contemporary regarding AF speed and also 3 settings for OS. If you change the OS to Dynamic you should get the best stabilization, it should make a big difference.

Have it set to dynamic os and focus priority. It is not as fast as the Tamron with those settings.
Then it seems like the Tamron has the fastest AF. That's good for people who has it or decided for Tamron. I still haven't decided but Sigma is still on preorder and I hope there will come a lot more info and pictures before I have to decide what's important to me.
Re the AF speed, you can do the same thing with the latest Cameras, I have my Servo first image priority set to 'Focus' and the second shot to the mid point. This works fine for most situations but I was out today having a crack at some Swallow in flight and found that 'focus' priority was just not quick enough to latch on before they were out of shot most of the time - I switched the first image priority to the mid point and it at least took a lot more shots with an AF over the bird albeit not all in focus but a few were (I just need to remember to switch it back to 'Focus' when finished).
Were the sharpening settings the same on this shot compared to those from previous times? It looks like the setting might have been a bit high, that is why I am asking.

Isaac, if you look at the shoulder (scapulars) they look like they should have an olive color overall, but if you look at the edge of each barb in that area it looks white. I am just wondering if that was the way it looked in real life or if sharpening has increased the contrast in that area. I see similar effects elsewhere on the bird.
