My query is to those who have moved from the D700 to the D800 -- and it focuses on usability in low light situations that require high ISOs to get adequate exposures.
I use two D700 cameras. My photography includes aerial work, event coverage (conferences, meetings, etc.) and what I call "location photography," which spans the gamut from construction sites to what can also be termed photojournalism. In fact, I do substantial work for a small midwest weekly newspaper, including sports photography in some dimly lighted high school gymnasiums. By dim, I mean ISO 6400, 1/200th at f4.
Finally - my question. How do you feel your D800 performs at high ISOs when compared to results from your D700 in similar situations?
