SUBJECT : Compatibility of F-Nikkor Optics with the Nikon Z System
When can we expect Nikon to honour marketing statements, and upgrade the FTZ adapter to enable:
1. Full support of AE with AI and AIS F-Nikkors on the Z System?
2. An acceptable autofocus on System Z cameras with "screwdriver" F-Nikkors including many AFD lenses, such as the superb Defocus-Control Nikkors, 200 f4AFD and 180 f2.8AFD?
Thanks to the built-in motor, the autofocus on D lenses works properly on the D850 and similar DSLRs. The ideal FTZd (to coin a term) needs a built-in focusing motor together with a functional Aperture-Indexing mechanism. There is a significant cohort of Nikon Owners, who will not hesitate to buy such an adapter for their Z Nikon cameras. As I explicate below, the FTZd will appeal to first time buyers too.
As we read, the marketing copy emphasizes:
“Great glass endures. That's why Nikon cameras—from the Nikon F in 1959 all the way to D850—have remained compatible with nearly all F-mount NIKKOR lenses. Why would things be any different with the Nikon Z? The Mount Adapter FTZ lets you keep shooting the lenses you know and love while also gaining the benefits of the new Z system. The legacy of compatibility continues.
And reading further:
“…So many possibilities.
Compatible with a huge selection of NIKKOR lenses.
The Mount Adapter FTZ works with approx. 360 lenses in total, 90 of which are AF-S, AF-P or AF-I type and have full AF/AE capability.”
More specifically, we read: “Nikon’s new mount system plays an essential role in the realization of this unprecedented imaging system.
What’s more, the Mount Adapter FTZ allows long-time Nikon users to continue utilizing their existing NIKKOR F lenses seamlessly with the new system.
Shooting with AE is enabled with a total of approx. 360 types of NIKKOR F lens from AI type onwards, while shooting with AF/AE is available with 93 types of AF-P/AF-S/AF-I lenses,
ensuring the same operation as with the new Nikon mirrorless camera system.”

For how many pre-AI lenses (ie older models) are adapted to Auto-Index on Nikon cameras? Moreover, is not “Shooting with AE is enabled with a total of approx. 360 types of NIKKOR F lens from AI type onwards” stretching the scope of an advertising slogan? At least 75% of these lenses do NOT register the aperture setting in the EXIF fields of a Z6 nor Z7 camera. This is infuriating in my experience. In light of the F-Mount legacy maintained into the higher level DSLR models, compatibility of only 25% (likely less) of F-Nikkors is a poor show in the support of acceptable functionality on Z Mirrorless cameras.
The above problems with the FTZ adapter continue to fan heated discussion on Online Photography Forums – two are Digital Photography Review and Fred Miranda. There can be no excuses here. Should you hasten to reply that these lenses are older pre-AFS models, there are dedicated Nikon agencies who still sell 8 AIS lenses as New, and no less than 11 AFD models. We must single out the two Defocus Nikkors – the 105 f2AFD and 135 f2AFD. These are unique optics not updated to any G or E portrait prime lens. There are many more Classic Nikkors: the 28 f2.8AIS, 55 f2.8AIS, 85 f1.4AFD and 105 f2.5AIS are four of my great favourites.
See:
https://www.graysofwestminster.co.uk/products/lenses-manual.php and
https://www.graysofwestminster.co.uk/products/digital.phpThe Strategic Fulcrum : Nearly all these AIS and AFD F-Nikkors are in many cases unique and unavailable in G or E mounts (without switching to a Sigma or Tamron). Besides the bonuses of IBIS, Focus peaking, and VR, AF support on the Z6, or Z7 will be a big help to anchor swift focusing with AFD lenses, there are many Nikon owners who treasure these Classic Nikkors for their unique character in rendering the image. And do not overlook how many videographers still favour Classic Nikkors as the optics of choice; is not the video is market a focus of the Z system? The venerable, if not iconic, status of these Nikkors is one manifest reason why complaints will persist against dropping compatibility off the FTZ.
May I suggest Nikon marketing read through the discussion threads on online Forums - with due attention. It can be argued these posters can only represent a minority of the global population of Nikon owners of pre-AFS F-Nikkor lenses. Dare I suggest certain of these posts point out the strategic advantages to Nikon to prioritize closing the gaps in F-Nikkor compatibility? Beyond Nikon honouring the marketing slogans [viz. “Shooting with AE is enabled with a total of approx. 360 types of NIKKOR F lens from AI type onwards”] there are obvious strategic benefits to expand its customer base. For one, a fully functional FTZ adapter will give the leverage to emerging photographers to buy their first Z Mirrorless camera, because the FTZd will enable them to start with affordable Used F-Nikkors; as a first step into the Greater Nikon Ecosystem. These Classic Nikkors are the first critical step: the functional lens system they can grow, given time. Yes, they may not even buy a system Z kit lens, but the strategic benefit hinges on growing the percentage of younger buyers of a Z-Mount Nikon camera. For many, their purchase is the cusp of an investment. They will expand it to own Z-Mount optics.
https://www.dpreview.com/forums/post/62323663https://www.dpreview.com/forums/post/61761736This cadre of potential Nikon customers is exemplified by the students, on tight budgets, who buy into a Z Nikon MILC as their first proper camera, but they then struggle to afford new lenses. It would be a serious mistake to dismiss students and younger ranks as low spenders. Consider, given time, how many of these owners of a Z MILC will become higher income earners? Once employed, a notable percentage will fulfil their aspirations, and build up the Nikon system they bought into earlier (as a teenager, or thanks to an anniversary gift, or inheritance etc). Consider the alternatives open to aspiring photographers - buy a Canon or Sony kit, and get locked into that lens mount.
If the strategy is to set constraints: thus to try and force committed Nikon owners to buy G or E Nikkors, then please rethink the tactics very, very carefully. Many customers see through the obvious. In response, one hears some are selling up their older Nikon gear for new Canon or Sony etc. For not all are heavily invested in current Nikkor optics. In my case, these include 58 f1.4G, 70-200 f2.8E, 300 PF, 400 f2.8E, 500 PF, and all 3 teleconverters (to itemize eight optics). As the situation stands, I persist with the Nikon system begun in 1984, which I know and grown to trust. Thus, I also rely on AIS Micro-Nikkors, and keep shooting my other AI, AIS and AFD lenses. The latter make up a total of 12 optics; I keep at least 2 of these in active use since 1988. My list of current equipment is registered with my Nikon UK account.
Great Glass Endures : Nikon’s legacy of “Retro-Compatibility” has persisted with the top range DSLRs (D850, D5 and others), which maintain F-Mount compatibility. The lapse of support of acceptable functionality since the introduction of the Z system impinges on customer trust. The current FTZ undermines potential. It sours the user experience with these superb cameras. Effectively, Nikon has discarded practicable support of no less than 75% of the capable F-Nikkor optics, which remain fully functional on the top-tier DSLRs. Support of less than 25% F-Nikkors is nothing to be proud of. For their loyalty, committed Nikon owners deserve better reciprocal support.
So we should also think long and hard about the ‘Old Lens Revival’, as its aptly termed by Nikon’s own Optical Maestro, Mr Haruo Sato [1]. He describes how this new market has its own momentum, such that certain Classics now cost more, and are becoming harder to find - “Over the past few years, we have seen the revival of one old lens after another. I think that the primary reason for this is the fact that mirrorless cameras support mount adapters that allow users to play with a wide variety of lenses. Photographers are taking a new look at their old lenses, and rediscovering the soul that still resides in these once dead-stocked lenses. This is a wonderful thing. Many F-mount lenses especially have an incredibly long life if not discarded, enabling users to enjoy unique differences in their rendering characteristics.”
Great Glass endures, definitely. Surely, it is Nikon’s own Z cameras we should see spearheading ‘the revival of one old lens after another’? Many of us Nikon owners sincerely hope you close this glaring gap in FTZ compatibility with the Z Cameras. In today’s digital imaging market, the strictures and challenges of selling Interchangeable Camera systems demands exploiting the tiniest of strategic advantages. F-Mount compatibility has set Nikon apart since 1959. Has Nikon now dismissed this unique strategic strength? The choice rests with Nikon. Although we rely on the latest advances in optical and imaging technology in the newest Nikon cameras and lenses, quite a few of us are fiercely proud of our collections of Classic Nikkors! The current situation should not undermine the excellence of Nikon’s emerging flagship – the Z System. Please embrace and extend this unique opportunity. Many of us aspire to see Nikon’s status not only endure but grow.
