I took 2 shots. One from basically the same spot as you and one from further back on my card. Default settings of 16x12 @ 4aa/16af
Compare and see. The grass doesn't show in the shot that is farther away but it shows clearly in the shot like yours. If anything I think I was farther away in my first shot than yours but its close enough.
Hope this helps in your assessment.
Btw absolutely love the way people are leaping all over this w/o any info to backup their comemnts
Spin away, woohoo.
