I had a HP photosmart back in the day that I liked, until a new version of windows came out. They would not update the drivers. So my fairly expensive printer was now a brick. I will never buy HP products again.
No. I will never go back to a cropped sensor. My shooting style doesn't require the 5d3 AF, bit low light performance is a must. If I were getting paid to shoot wildlife, I would consider it. I think the 7D2 will be great. I had the original and liked everything except the ISO noise.
