One of the things that has made me hesitant to purchase a D700 is finding a good FX replacement for my 16-85 VR zoom. Its important to me to have a 24mm wide end. The f2.8 Nikon is way too heavy and expensive as well. I would like to hold the maximum weight to 650 grams as I carry the camera for up to 12 hours at a stretch while traveling. Even the less costly Sigma 24-70 HSM is too heavy, although the older model might cut it. Nikon's 24-120 looks like a replacement for me in terms of FOV, but its reputation for being a weak lens is enough to keep me away. I have met a few folks with the older D model who hate it. From what I can determine by reading various reviews, the discontinued 24-85 f3.5-4.5 AF-S is a good performer, even better than the more available 24-85 f/2-4 D model. Is there something else that I am missing, or am I getting the wrong impression on anything?
