Undertstanding the Auto-Focus System of the Canon EOS 7D
Interesting post by New Zealand based photographer Andrew S. Gibson. The almost 4 years old Canon EOS 7D (price & specs) is still an outstanding DSLR, with an advanced AF system not previously seen on a Canon APS-C sensor DSLR (and still not featured on any other Canon APS-C DSLR). The AF of the EOS 7D is more advanced than the one sported on the EOS 6D. If you want a more sophisticated AF system you have to go at least for the EOS 5D Mark III.
