So I have been thinking the EXACT SAME thing as JR...that's it's soft. I focus locks, I take the picture, and the image is soft. In camera I'll zoom to 100% and see how soft it is. It has been driving me nuts. About 20% of my photos are sharp, but even still, not that incredibly sharp. I was SURE it was my unit, and I had played around with af fine tuning...but decided to print out the test that was posted here earlier. I printed it out, did the test and WOW! That helped TREMENDOUSLY! My camera/lens was backfocusing. I had to set it to -15 to get it in the sweet spot. Now the images are MUCH more tack sharp. Thank you for posting that link to the Focus Chart. : )
