I do most of my shooting in the backcountry, so weight is quite important to me. Lately, I've been noticing the lack of focal length between my Sigma 10-20mm and Nikkor 35mm 2.0 (205g). I also carry the Nikkor 50mm 1.4 (230g). One obvious solution is to buy a Nikkor 24mm 2.8 (270g). Another solution is to buy the Nikkor 24-70mm 2.8 (900g), and leave the two primes at home. This kit would be about 195g heavier than the 3 primes (roughly the weight of another prime), not to mention $1400 more expensive (perhaps I would sell the two primes ... not sure). From what I've read, image quality between the two options is not significantly different. Maybe a bit better sharpness with the primes, but less flare and ghosting with the zoom. However, as I do not own any of Nikon's latest-and-greatest glass, I have to admit to being quite curious as to what the hubbub is all about. Am I $1400 curious? Maybe. I would like to hear from people who have made a similar decision, and what they discovered after making that decision.
