I bought this lens 4 years ago and have always had problems with depth of field. Have played with all settings including aperture and still have crappy depth of field when zoomed in. I always thought it was me or something I wasnt doing, but recently had a much better photographer look at it and they came to the same conclusion. Now my question is: Is it just my lens that is possibly defective or are they all like this? I was using a tripod and photographing birds in my flowers and two birds not even 1 foot apart, one was in focus the other was blurry.
