I was out with the family today with my D7000 and found what looks like Moire' to me....
This was on my 24-70 F2.8 @ F5.6 1/1250 iso100
For these kind of pictures, I don't think it's a big deal... for wedding's... well different story.... The big thing to note here is that this was on a man made net... In nature, should be rear... Attachment#1 (jpg file) Attachment#2 (jpg file)
