Here is the first picture I took with ny new D600.
50mm, f3.5, 1/200, iso 6400 @5:30am
Resizing and sharpening was the only pp done.
Here is a 100% crop.
Sharpening only. Camera hand held.
The race is on to catch the best fish. Cropped, sharpened and resized.
I'm extremely happy with the results so far. Next step will be to see how it performs with a dx lens.
