I was out shooting some birds this weekend (well trying) but none of my shots really came out. I know a good deal of this was due to only having a 200mm lens for my d70s so I couldn't really get them frame filling. However for an egret I was able to get pretty close and fill most of the frame. I was shooting at f8 or 11 (depending on if it was in shadows or not) but the images where still soft. In addition I noticed a blue halo along the back of the bird. I don't know if it was because this area was the highlight section and being slightly blown out or if its because my long lens is not the best. (tamron 80-210 f4.5-5.6 if I recall right). I don't have the pic here at work but am wondering if anyone has a clue as to if it is the fact the lens is fairly cheap or if it is something else.
