I found a willing participant yesterday for my own Autofocus bicycle rider test. No swerving though at the speeds this guy was going. If anyone cares to view them I posted all 21 of the series from start to finish on my Flickr site
Larry Mc | Flickr The shots are consecutively numbered from beginning to finish and the Flickr page will show my settings. I shot with the 55-300 PLM, Its hard to find any fault with the series they are SOOC JPEGs with no sharpening or any manipulation of the files with only my Copyright Signature added by DXO PhotoLab. Check them out and let me know what you think.
