Overblown Arguments Over Third Party Support of Nikon Z8 Firmware 3.00

As I had mentioned in my post a couple of days back, there have been reports of Tamron lenses not working, either partially or completely disabled, with Nikon Z8’s latest firmware 3.00. Tamron themselves have also posted a service advisory regarding this issue on their official site.

I do get that some users are frustrated over the fact that the native Z-mount Tamron lenses that they own are not fully compatible with the latest Z8 firmware, even though Z-mount Tamron lenses are supposed to be developed under license from Nikon.

In addition to that, several new reports of third party mount adapters from Megadap or Techart are not working as well after the update have also surfaced in the past couple of days.

And this has let to quite a bit of overblown arguments online with regards to who is to blame for this and in more extreme cases, how this firmware update is entirely not up to par, leading to some users calling it a fiasco of an update.

To be honest I do think this is quite a disappointing reaction to see from the users, especially considering the fact that many new features have been implemented in this new firmware update, so calling this firmware update a failure just because third party support is not perfect somehow sounds to me like an entitled user whining.

Before I continue, I think Tamron needs to be given a huge round of applause for acknowledging the issue early (literally the same day the firmware update was released) and letting users know that they are looking into the situation. It is indeed a good move from them to instill confidence in their customers.

So now, we all know that firmware updates (no matter major or minor) have shown time and time again that third party electronic peripherals, be it lenses or batteries, may no longer work as intended due to protocol changes or code changes. This has always been the case, so usage of third party accessories will always bring this risk as manufacturers might update certain safety or security protocols and do not guarantee full compatibility with using said third party accessories; even more so for accessories developed through reverse engineering of the electronic protocols.

I know this first hand - I sent in my D800 for routine maintenance in the past and the service center updated my camera to the latest firmware, which led to my Sigma 35/1.4DG HSM being unable to autofocus at all. It was fixed by updating the Sigma lens via the USB Dock.

The main argument for this current problem right now is that Tamron officially developed the said native Z-mount lenses under a license from Nikon, and because of this the lenses should work as intended with the latest camera body firmware update as it is released.

Unfortunately I think that this argument is not sound at all, since it would mean that Nikon would have to develop its firmware around how Tamron writes their lenses’ firmware, either that or Nikon would have to wait for Tamron to finish up updating their lenses’ firmware before releasing the Z8 FW3.00 penalizing users who are using native Nikon lenses.

Either of these scenarios just sounds improbable from Nikon’s point of view don’t you think?

On top of that, the actual licensing of the lens mount protocol from Nikon to develop the lenses is not a transparent transaction - apart from the manufacturers themselves (and I would argue even so only a handful within the organizations), no one else outside that circle knows what exactly is being licensed and what kind of royalties are in play over here.

If you look over the fence at the E-mount system, Tamron, and even Sigma, release firmware updates for their lenses every now and then when a new body is released or a firmware update for a current body might have changed something. So this is not exactly something new even when things are being developed in partnership or under a license.

Some argued that Nikon should have sent Tamron a beta copy or SDK of the FW3.00 so that they could prepare firmware updates for their lenses when FW3.00 landed. I do agree with this argument, since as partners this should be the case to maintain the relationship down the road, and if Nikon did not send them any prior information or SDK for Tamron to update their firmware, then I do agree that it is a huge oversight on Nikon’s end, especially considering that Tamron does have quite a fair bit of lenses for the Z-mount.

But objectively speaking, no one knows whether Nikon did or did not send them a SDK, and no one knows if Tamron has perhaps already been working on updates for their lenses prior to the release but just unfortunately could not make it in time for the actual release of FW3.00.

The 2-week gap between the announcement of Z8’s FW3.00 and the actual release date might actually be a little hint that there was more going behind closed doors than we are allowed to know.

Also as of now, it is not as if the lenses are bricked totally (since many users do comment that the lenses have no issues working on their other Z bodies), and the main culprit seems to be the newly added Focus Limiter function. Furthermore, Nikon is one of the few camera manufacturers I know of (or in fact, the only camera manufacturer) that allows you to rollback your firmware to an older version if required.

So right now, if you are using Tamron lenses as a main lens on your Z8, you have these 3 options:

1. If none of the FW3.00 new features are immediately crucial or required, just rollback to FW2.10 (or not update your Z8 if you have not done so) and you will get the full intended compatibility of the lens and body as it always has been.

2. If you need Focus Limiter, run Z8 on FW2.10 and use Tamron Lens Utility software to customize the custom function and button to map Tamron’s version of Focus Limiter to the lens.

3. If you need FW3.00 features other than Focus Limiter, update your Tamron lenses, disable all custom functions on the Tamron lenses (especially Tamron’s version of Focus Limiter via the Tamron Lens Utility software), and the lenses should work as intended on Z8 FW3.00. Do note that this might still cause some unintended hiccups here and there since Tamron has not officially come out to mention what other compatibility issues are there.

However if you are in the group which requires both FW3.00 features immediately and the Focus Limiter ability, your only choice is to just sit down and wait for Tamron’s firmware update. And also perhaps ponder over the above 3 suggestions I gave regarding to workarounds right now.

Lastly, regarding other reverse-engineered lenses and mount adapters, the final verdict on their compatibility is still hazy at best, but to play safe it is best to just stick with FW2.10 for now while keeping a lookout on the respective manufacturers’ websites for firmware updates in the coming days.

To summarize everything up, yes the firmware 3.00 for the Nikon Z8 did cause some compatibility issues with 3rd party lenses, even for those developed under license from Nikon. But to be fair we do not know what the license covers, and we also do not know whether Nikon themselves actually did provide SDKs to Tamron prior to the firmware’s release as part of their partnership. It always has been up to the third party manufacturers themselves to ensure compatibility, and if you need your gear working right now you could just rollback the firmware to the older FW2.10 and have everything working as it was.

A little patience goes a long way, so be glad that there are options to make the gear work just as it was. Go out and enjoy shooting!
