For reasons that this review hopefully makes clear, the Nikon Z 14-30mm f/4 S lens is one of the more controversial Z lenses to date. At its best, it’s excellent – somehow cramming a filter thread, a class-leading zoom range, and top-of-the-line performance into a seriously portable package. It lives up to the promise of what a mirrorless lens can be.
At its worst, you’ll see insane distortion – nearly fisheye level – plus heavy vignetting. And, most troubling of all, it comes with an apparently high potential for decentering and sample variation issues.
So, which of those two takeaways is more representative of the lens as a whole? A large part of the answer, of course, depends on the 14-30mm f/4 sample you get. The rest is up to your level of acceptance for modern lens designs, which excel at things like sharpness and flare, but are starting to leave “correctable” qualities like vignetting and distortion up to post-processing software.
It’s a dilemma – and, aside from sample variation, it’s a dilemma that is growing more and more common with each new leap in mirrorless lens design. I’m personally a fan of the new direction, but I can see why many photographers would not be.
- Very light weight and small size, especially for a 14mm zoom
- Takes slim 82mm filters without a significant vignetting penalty
- Capable of extraordinary sharpness, about as good as you can get in an ultra-wide zoom
- Fast, quiet, accurate autofocus
- Minimal flare
- Minimal chromatic aberration
- Good weather sealing (considering it’s an external zoom)
- Seemingly high sample variation, with heavy decentering in some copies
- Extreme distortion and strong vignetting in uncorrected images
- 14mm corner performance is good, but not great – the weakest point on the lens
- Ergonomically, focus by wire can be frustrating for manual focus
- Fairly expensive at $1300
This is a hard lens to recommend, but it’s also a hard lens not to recommend for Nikon Z users looking for an ultra wide.
I think the distortion, vignetting, and focus by wire issues are going to be similar across many/most Nikon Z lenses, especially zooms. At this point, I’d say make your peace with that or choose a different camera system.
That leaves two major concerns affecting this lens in particular: price and sample variation. So far, all of Nikon’s other Z lenses have had impeccable consistency from copy to copy, at least in all our tests at Photography Life. It’s unfortunate to see that the 14-30mm f/4 does not continue that trend. If you can guarantee that you get a good copy, I’d say go for it – but for most photographers, I’d think carefully about spending that $1300.
Personally, I’m planning to buy this lens. Again, it’s one of the best, lightest 14mm zooms on the market, and it takes filters. But I’m lucky enough to have Nasim’s excellent copy nearby to compare against and make sure mine is reasonably close. If you don’t have a good way to test multiple copies of the 14-30mm f/4 side by side, or especially if you live somewhere that makes it difficult to return an obviously bad copy, it’s clearly a harder sell.
So, what are your other options? As sharp as the 14-24mm f/2.8G is, the flare performance and weight make it difficult to recommend for Z users. Two lenses that improve on flare performance, and arguably even sharpness, are the Sigma 14-24mm f/2.8 and the The Tamron 15-30mm f/2.8. Those both sell for $1300, although you can get the older generation of the Tamron used for $800. Except both lenses are even heavier than the Nikon.
Maybe the answer is something that doesn’t go to 14mm or 15mm at all, like the Nikon 20mm f/1.8G or the new Tamron 17-35mm f/2.8-4. Perhaps you should even wait for the Nikon Z 14-24mm f/2.8 S that will arrive in 2020, likely to be a stunning lens.
In truth, I don’t know. Designing wide angle lenses is hard; so is picking the right one. The Nikon Z 14-30mm f/4 gives everything else a fair run for its money, but it’s far from perfect. If you can live with the flaws – and the uncertainty about getting a good copy – don’t let me stop you. But, at a minimum, I recommend that you buy it from a store with a good return policy.
