I'm considering going D700 + 24-70 f/2.8, any suggestion ? I wanna jump on the fact there are now many D700 sold everywhere cause of the D800, and new ones are cheaper than before. The D800 seems so appealing but I can't justify the difference in cost, although the ISO sensibility has increased as well as the sensor (30mpxl is maybe overkill but the fact you can chose to work in lower resolutions makes it very nice).
Should I consider the Nikkor a life investment or should I take into consideration the Sigma 24-70 which is half the Nikkor's price for a "comparable" result, or even the Tamron 28-75 which is a fourth of it ? Seems like those other options (all f/2.8) are bigger bang for bucks, but at the same time, I read more stories of quality problems (on the sigma, seems like 1 out of 3 need to be sent back to them cause of front/backfocus very obvious in lowest f settings or other quality issues). Although, it's maybe too bad investing so much into a body if it's to put a low-cost lense (tamron), while it's the most important part of a camera.
Should I even consider the 24-200 ?
D700 used if possible, and I'm considering buying the 24-70 new because it's the kind of lenses you keep your whole life. It's also hard to find any used one because of that same reason anyway, at least here.
Would probably be for summer though
