I have been reading about Canon’s new 20D digital camera on Fred Miranda’s forums and how some ppl have had issues with focusing. Having read about similar problems with the Canon 10D which I just purchased not to long ago I decided to test my AF (Auto Focus) out. There was a link to an article in the forum to the “Focus Test Chart” and also a pdf to help with testing your AF. The paper gave me a great understanding about how AF works and explains why I get out of focus photos some times. It has been USER ERROR! Not the camera. Well I went through the quick process of shooting the supplied focus test chart in the pdf and had no problems with back or front focusing (see pdf for description). I have also made a link on my site in case the other site goes down because this is so helpful. Link to local copy. Try it out today on any camera that uses Auto Focus!

Michaels last blog post..Mal wieder: Socken stricken
Michael,
Thanks for the heads up. I actually found the link has changed with a quick google search. You can find the new site here: http://focustestchart.com/chart.html
I’ll also reflect the changes in the post.

Is that a good camera for wildlife photography? I will be traveling to Africa pretty soon and would like to make sure the camera I get can get me some good shots
Thanks for such interesting post.
Auto focus are very useful for clarity purpose.
Thanks for the sharing.
Canon 10D is an excellent camera for the professional photographers. I don’t like to shoot pictures in AF mode. For outdoor photography I like to experiment with different lenses with point to the object manually.
