This is one of three 'trinity' lenses any Nikon Z9 or Z8 owner will have on their shopping list. A constant-aperture f/2.8 24-70mm has become a standard fixture in any premium camera manufacturer's lens range. But while the NIKKOR Z 24-70mm f/2.8 S might look the obvious choice, it
Sharing the same 72mm filter thread as the Nikkor Z 24-70mm f/4 S standard zoom, the 24mm is also a very similar size and weight overall. As usual for Z mount prime lenses, there’s a switch for auto/manual focusing and the large manual focus ring is electronically coupled to the stepping motor that drives autofocus. Furthermore, you canThat said, the 24-70mm f/4 S often comes with a steep discount when bought in a camera+lens bundle, so cost can come into play, too. Frankly, I wasn't expecting to like the 24-120mm f/4 S. That was clouded by my opinion of the two previous Nikkor 24-120mm lenses in the F-mount, which both had very clear liabilities.
Having said that, here’s the quick-and-dirty verdict regarding the Nikkor Z/S: It’s big and heavy, indeed it’s the same weight as Canon’s DSLR 24-70 mk2. However, it still manages to be lighter than the mirrorless full-frame 24-70mm f/2.8’s from Canon and Nikon, and also lighter than the behemoth Nikon F-mount 24-70mm f/2.8 VR.If you just have to have f/2.8, get an FTZ and either the older f-mount 24-70/2.8 AF-S (non-VR) or whichever Sigma/Tamron fits your budget, or maybe even the even older Nikkor 28-70/2.8 AF-S. I think 24-70/2.8 zooms are overrated for most enthusiasts though and not worth the cost, size/weight penalty and limited zoom range.
I don't know that the f/2.8 is that much better optically. The f/4 gets really good reviews on that. The difference comes in how much you treasure defocused backgrounds, which for videographers is a pretty big deal. Many pros want that extra stop and I have a 24-70 f/2.8 in my F mount kit.
