The 24-70 will perform better in low light conditions due to the f/2.8 fixed aperture. The 24-120 will go no wider then f/4. That said, that "might" be good enough for you, since the D750 itself performs very well in low light, so only you can decide whether you need that full-stop more light from the lens itself.At similar aperture settings, I think you'll also see the Tamron giving better IQ. The obvious benefit to the 24-120 is the extra reach. All that said, the 24-120 is no slouch either ... it's my normal go to lens unless I need that extra stop. I'm shooting a D7100 vs the D750, so not having the same low light performance in the camera body I'll go to the Tamron any time the available light is questionable.</blockquote>
