Looking at your long list of lenses and the EXIF, I'm assuming you shot those with your Sigma 70-200? Do you know how that lense compares to the (slow AF) DA* 50-135?
Gull shots are very cool too, like someone else mentioned it's great seeing the full sequence, OOF and all. Really helps to evaluate the cameras performance better than a lot of "in depth" reviews (although they're great for what they are).
The 70-200 seems to perform somewhat better on the k5 than on the Kx or my previous K7. It seems quieter which is strange, maybe it's not working quite so hard. It locks on quicker too with less hunting.
The reason I used it for these sequences was that it does stop down to 2.8 so the DOF is pretty shallow and more of a challenge for the AFC. Some of those are in my dropbox and the link is upthread. I don't have the da*50-135 so I can't compare. I do have the DA*300 f4 which I love, it's a great butterfly lens as it close focuses.
Thank you for your appreciation.
