Foxcow: I've made sure everything is clean as a whistle.

OK, I set up a test image and took about 50 shots. First, I took shots from the tripod and in Auto mode. I used a 2sec delay to remove any chance of camera shake on my part and I used IS1 for every shot. I tried focusing on the black line in the center of the paper (it has the words "focus here" printed in white).

Here are the shots taken:

14mm with auto-focus then another with manual
42mm with auto-focus then another with manual
40mm with auto-focus then another with manual
150mm with auto-focus then another with manual

Manual focus was done with Live View and using Live View Assist at 7x magnification.

For every AF shot, the bottle might be in focus but the paper is slightly blurred. I assume this can be chalked up to a short depth of field?

For every manual focus shot, everything seems to be in focus. How can this be when the only thing changed is the focus method? Depth of field, shutter speed, and everything else remain the same, but the focus is much better!

Then I went back to hand-held mode. Again, every single shot is blurry. It's almost as if it hasn't chosen a focal point or the IS isn't working. I've held the IS button and hear the motor whirring and see the image stabilize. But all my hand-held shots with autofocus are blurry. The only thing with sharp images appears to be on a tripod with manual focus via Live View Assist.

The first image is at 150mm on a tripod with manual focus. Second shot is 14mm with Auto Focus.

EXIF for 150mm:
Exposure: 1/180
F-Stop: 5.6
ISO: 100
Aperture: 4.0
Metering Mode: pattern
Focal Length: 150mm


EXIF for 14mm:
Exposure: 1/60
F-Stop: 3.5
ISO: 100
Aperture: 3.6
Metering Mode: pattern
Focal Length: 14mm


I hope it's just my ignorance of a particular function because I don't want to have to send the camera back for repairs. If anyone can help me, I would sure appreciate it!
