Looking for general opinions on a lens. Going to Myanmar shortly. I have a D700 and am taking my 85mm f/1.4 and 70-200 f/2.8 for sure. I also have the 24-120 f/4. Question is should i take my friend's 24-70 f/2.8 instead of the 24-120? I guess my concern is quality. Most shooting will be done outdoors. Portraits will be taken care of with the 85. Any thoughts from the experts here would be appreciated. Thank you!
