Tracking test with my funny rig. (8 imgs)
I tried testing the tracking with the Pentax K-3 + Pentax 1.4X HD AW + Tamron-F Pz_AF + DA*60-250/4 with the lens set to 200mm. Multiply the focal length and aperture that you see in the EXIF by 1.4 to get proper readings.
I shot a sequence of 20 images. The first image below is where I aquired focus. All the others are the 7th thru the 13th images. I used AF-C Expanded (9 points). Not too bad IMO. I didn't plan on this until I actually did it. Otherwiise I would have lowered my shutter speed and ISO.

Carl - 'What do you mean? It will only take 1/1000s.'
