Well you know how it goes.....with big purchases like this , sometimes you need to feel just a bit "cozier" with the decision. Howard is correct in that better positioning is key. I never work a tourney or event where I don't have access to the optimal positions. Its key...I agree.
The D4 will be the selection. Ultimately I may get a D800 too but I just don't do enough studio or landscape work to make it worthwhile. YET !
