I tested my lens (24-70mm) again today and noticed something "weird". It seems to be focusing on the wrong spot. For example, let's say I focus on the letter "E" in "Exposure", the E would come out decenly sharp while the X and P would come out even sharper. See below.
1st pix- focused on the center of the flower on the right (the wholesome looking one). The flower in the back seem to be about the same sharpness yet the pedals between the 2 flowers are blurry.
2nd pix- focused on the word "the". It looks a lot more blurry than the specs on the black sheet it's resting on.
