I have now made the bold (? foolish) move to sell all my Nikon gear, for a variety of reasons I can go into but largely because of having the Sony A7r - but it did leave this one hole.
Here's from this morning's trip to the Calgary Zoo.
I actually want to go back and reshoot the owls with my A7r , 400 mm. not cropped, and with tripod so I can reduce the ISO. That said, ISO 6400 isn't bad on the 70D. "Grain" on a 13X19 print is visible in the eyes and beaks, but probably less than Tri-X in the old days - we live in wonderful times.
