“If all three of these lenses were the exact same price, I would probably choose the Nikon but it’s basically double the price of the competitors.
The Sigma lens was certainly my favorite to look at but it couldn’t quite keep up with the Nikon or Tamron when it came to ergonomics, image quality, and stabilization. For the past few years,
I’ve owned the previous Nikon 24-70mm lens without VR and the previous Tamron 24-70mm with VC and I exclusively used the Tamron. Literally, my only gripe with the old Tamron lens was that it was ugly and it felt cheap.
I’m happy to say that Tamron has fixed both of those issues and they have produced a lens that I think looks much better than the Nikon version and is actually on par with it functionally.”
