Re: Canon 450D autofocus problems

I have the 450d with 60k shots on it.  Why select anything except the center focusing point?  Why let the camera guess as to what you want to be focused?

The camera will often select something in the foreground to focus on since objects which are closer will inherently have more detail/contrast.  Also, the center focusing point has more precision is my recollection.

When the 450d came out, there were lots of posts like yours, and selecting the center focus point is one part of the solution.

If I'm shooting a landscape and want the image to be as sharp as possible, I use live view mode since then there is no worry over calibration of the lens and body, and the potential phase focusing sensor misalignment issue goes away.

If you have enough light, stepping down many lenses to F8 is where they are the sharpest.
