Yesterday I went again too the Red deer In the Nationaal park in holland. The weather was a little bite cloudy en it was not too warm. Often we hear a burl but nothing happend so far.

Willem, The 1D Mark III will perform well up to ISO 1600 without significant noise. I would suggest a higher ISO here and more exposure as Peter mentioned.
