Um...mightn't the camera model be a relevant variable in this discussion?
That is very possible. Different versions of Safox might react differently under the same conditions

Here's something worth trying... zoom in tight, focus, and then pull back.
I should point out this is the technique used in television, both in the studio and out on location.

Hi there! I too have the same lens and have no problems shooting under similar conditions as how you were shooting. Here are some shots indoor but against strong lights which were taken at a FL around 70mm, aperture of f2.8 and ISO800 with my K200D:
I don't think the background light in these samples is comparable to the intensity of the sun in the sample posted by the OP.

Beg to disagree. The second photo shows that most of the direct sunlight is blocked out by the line of trees.

Are you implying that the K200D's focusing is better than that of the K5 under these circumstances?

Not at all. I just didn't see any mention of the body model and I'm under the impression that AF systems vary from model to model.

Oh. I was under the assumption that you had also checked the EXIF and knew that the DSLR used is the K5.

And I maintain that still is exponentially brighter than all the artificial light in the collective sum of your samples.

I will try to recreate the problem when I have time and I will keep you guys posted. Hopefully it's not something that will happen often.

Ok guys, here are some other pictures. I took these with the same intensity of backlighting and what I noticed is when I shot in landscape mode, the focus would lock correctly more often, I focused on the corner of the chair...when focusing in portrait mode, the focus was having trouble locking, it locked but was off and instead focused on the leaves as you can see in the second set of images, focus still was on the corner of the chair. I was using center focus point.

Hmmm. Interesting. Have you tried shooting in AV or M mode?

Sorry, I misunderstood the modes (thought it was a presetting that some models have). I notice a rather large sun flare in the portrait test photo. Did you buy the lens new or used? Your lens seems to loose a rather strong amount of contrast when shooting towards the sun.
