Hi I recently upgraded to canon 1 dmk111 .i have a canon 600m prime lense .problem I have is indifferent results compared to my 40d .the woodpecker the one which is on the long log is 30ft away seems sharper .yet the neares one which was only about 18ft away looks soft .weather dull ISO 1,000.f5.6 .800/

To me the difference in sharpness seems to be the light. Your shot from farther away had better (though not perfect) lighting compared to your closer shot, which seems to be in shadow. The better light, the sharper the photo. The focus also doesn't seem to be spot on with the closer woodpecker. That's just my take
