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:
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.
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.
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. (Update on 16/07/2025: Firmware 3.01 is now out by Nikon which addresses this issue, so you do not have to update each individual lens but just update the camera instead.)
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!
Nikon Z8 Firmware 3.00 Issue With Tamron Lenses
Just like to inform Z8 users out there who are using native Z-mount Tamron lenses that there is an issue with the newly released Z8 FW3.00 with said Tamron lenses.
With the new firmware installed, there have been numerous complaints and feedback regarding Tamron lenses not being recognized by the camera body at all.
Tamron has issued a notification regarding this issue at their official support site here.
Some users have found that by turning off the newly added “Focus Limiter” function, it solved the issue and the Tamron lenses would work as normal, but if you are worried about other functions breaking with the Tamron lenses (like custom Tamron button functions and such), I think it might be safer to just stick with FW 2.10 first until Tamron release firmware updates for their lenses.
I will update this page again when more information becomes available either from Tamron or Nikon.
** Update 3/7/2025
It seems that for the Tamron 35-150/2-2.8, as long as you’re running on firmware 2 on the lens, the lens works without issues on FW3.00 Z8 as long as custom functions are not mapped to the lens via Tamron Lens Utility and the Z8’s new focus limiter is turned off.
I suppose this should be the case for the other Z-mount Tamron lenses too, but I do not own them to test out.
** Update 16/7/2025
FW 3.01 is now officially out and can be downloaded here from Nikon’s site. It resolves the issue with Tamron lenses. My write-up of the patch can be read here.
Nikon Long Lens Options for Hobbyists
Recently I have been talking to a few of my friends who have just recently picked up photography as a hobby, and they are dabbling with the thoughts of getting some longer lenses to capture their kids’ events like sports day or drama performances.
As we brain-stormed through the various options available to the Z mount currently, it dawned upon me that the telephoto realm is really a dangerous spot for GAS, as for every option available, there is another option that would compensate the former’s weaknesses or compromises.
I thought that maybe it would be a good idea to do a very brief summary of long lens options that would not require incur the wrath of bankruptcy. So long-term GAS affected patients, please do not start bombarding me about the missing Z 400/2.8 TC or the Z 600/4 TC lenses in my list below.
Since technology would evolve over time, if any one happens to find this post in the future, please do take note of when this article was posted before you start to flame me with an option that was not available at time of writing.
Let’s start with bodies first. (Yeah I know the title said lens but, there are DX lenses too.)
With the introduction of the two EXPEED7 siblings, the Z50II and the Z5II, I think pretty much anyone looking at getting a new camera for kids’ sports should definitely consider either body. They share the same autofocus system, which itself is inherited from the bigger EXPEED7 siblings, so in terms of subject detection, autofocus tracking and focus accuracy they are just limited by their own sensor readout speeds.
Tight budget: Z50II. It is the most affordable EXPEED7 camera body now. And also being an APS-C camera, it would give extra reach with attached lenses, which is useful for our said scenario. Pairing it with the DX 50-250/4.5-6.3 VR could make a really compact telephoto set.
Some wiggle room for budget: Z5II. While it sits at the bottom of the full-frame camera line, it sports a very capable 24.5MP BSI sensor, which when coupled with the EXPEED7, delivers beautiful files and great autofocus performance.
Even more room for budget: Z8. It comes with a fully stacked 45.7MP sensor, which is a speed demon itself. The camera delivers blackout free shooting, which is very helpful for framing fast action shots. The 45.7MP also gives a lot of room to crop, which is beneficial if getting extra long telephotos is not feasible.
(I know the Z6III is omitted here. As of writing, I just cannot recommend the Z6III for such use case now due to its lack of customizations (due to be fixed in a firmware update), and the Z5II just provides a way better cost performance when compared to the Z6III)
Next let’s look at the lenses.
Tight budget: Nikon Z DX 50-250/4.5-6.3 VR. This lens when fully zoomed in would result in an equivalent 375mm lens, and when paired with the fast Z50II it should be able to tackle most outdoor sports events with no issues. However this option should only be considered if the Z50II is used.
Tight budget (FX version): Tamron 70-300/4.5-6.3 Di III RXD. It is the most affordable native Z-mount telephoto lens right now, although it only ends at 300mm. While might not be long enough for some outdoors sports events, its f/6.3 aperture will help tame the ISO a bit in indoor venues. It does not come with any optical stabilization system, so I highly suggest that you do not pair this lens with any of the current DX cameras.
Some wiggle room for budget: Tamron 150-500/5-6.7 Di III VC VXD, or Nikon AF-S 200-500/5.6 VR via FTZ. Both of these lenses go up to 500mm, with the Tamron being a native Z lens and slightly lighter at the expense of a slower aperture, and the Nikon requiring a FTZ adapter making the set front heavy. The Nikon should have no issues indoors as well with its faster aperture in the tele range.
More wiggle room for budget: Tamron 50-400/4.5-6.3 Di III VC VXD or Nikon Z 28-400/4-8 VR. While both of these are 400mm class lenses, their starting focal length and aperture ranges are very different. The Tamron has a slightly tamer maximum aperture range, and goes down to a normal 50mm view. The Nikon on the other hand goes all the way down to 28mm, but at the expense of a small aperture at telephoto ranges. The Nikon could be a one lens solution since it covers the wide angle range too, but its slow aperture means that it would struggle really hard in indoor situations.
Even more room for budget: Nikon 180-600/5.6-6.3 VR. I’d say just treat this as a constant f/6.3 lens. It’s an upgrade everywhere as compared to its predecessor, the AF-S 200-500/5.6 VR, and the only lens on this list that goes to 600mm, but ultimately as compared to all the other options here it is the heaviest and longest so that itself might be a concern too.
Image quality priority at non-bankruptcy budget: Nikon Z 100-400/4.5-5.6 VR S or Nikon Z 400/4.5 VR S. I think this should most probably be the reasonable budget limit for most users, and while they are both 400mm class lenses, their fast aperture (especially with the prime) would give the best image quality as compared to the other options here. It boils down to if you treasure flexibility (100-400/4.5-5.6) or pure speed and clarity (400/4.5).
One thing that was intriguing to me was how Tamron seems to be helping cover Nikon’s consumer telephoto range quite a bit, and I for one am glad that such options are available for the system, since most of Nikon’s own solutions cater to the slightly higher end of the spectrum.
I think that it would be nice to see more APS-C specific telephoto options, since now with the Z50II we now have a highly capable DX body. Perhaps it would launch with the unicorn Z80?
Updated Tamron 35-150/2-2.8 Usage Page
It has been about a year since I purchased the Tamron 35-150/2-2.8.
I’ve been using it with the Z6II, mainly for outdoor location-based assignments, and have updated its equipment discussion page with some further observations and thoughts that I have on this lens after using it.
Hope the information may be useful to anyone looking to get the lens (or trying to find out more about the lens).
Tamron 35-150mm f/2-2.8 VXD for Nikon Z-mount
This was one of the lenses that I had been envious of Sony users for a long time, and when the Z-mount version was announced in September 2023 I was definitely excited and grateful that Tamron had decided on this lens as one of the earlier ports to the Z-mount.
Having this lens would be a great help in solving my problem of having to switch between the 24-120/4S and the 70-200/2.8S during shoots - not that these 2 lens are slouches, and in fact I love using both of the lenses very much, but if I could have one lens that could do the work of both it would make me more efficient and also allow more options for me to include things like prime lenses in my double set-up.
That being said, having had a slightly negative experience being an early adopter (looking at you Z8 strap lugs), I decided to wait a bit for normal user reviews to roll in to see how the lens performs with the Z-mount bodies.
Based on the E-mount version’s reviews and user feedback, the general consensus on the lens has been positive with regards to the sharpness and overall image rendering, and I do not expect much difference between the E-mount and the Z-mount variants regarding the image quality.
Personally the few areas that I had interest or concerns in are:
How fast and accurate is the autofocus in normal modes and subject detection modes for Z bodies?
How fast and accurate is the autofocus in pin-point mode?
How prone is the lens to zoom creeping?
How weather resistant is the lens? (The exposed USB port seem like a weak spot to me)
After renting the lens for a bit to determine if it could properly act as a replacement for my 24-120/4S and 70-200/2.8S pair for assignments, there are some interesting observations that I encountered:
The lens boots up slow - even slower than the 24-120/4S. However, it is even way slower when waking up from sleep, so much so that many times I thought I had forgotten to turn on the Z6II I was using it with.
AF-S, AF-C and subject detection modes on the Z6II were pretty consistent and accurate, so I do not have much issues there with it.
AF-S pinpoint on the other hand is a slightly different story - perhaps the motor is not properly suited for racking contrast autofocus, but it feels sluggish and does miss focus a little more than I would like (I’d say in the range of 5% or so during my time with it)
Field curvature seems pretty strong on this lens, so using focus-and-recompose methods (even if it is a slight recompose) tend to make the initial focal plane soft - best to frame first and move the focus point (or use subject detection AF modes) to the intended subject and focus.
With proper focusing techniques, images are sharp in the focus zone and background blur is generally pleasing. While it lacks the minute detail acuity of the Nikon S-line lenses, the lens resolves detail very well and I think deserves praise for being able to do so given such a wide zoom range.
While I mentioned that background blur is generally pleasing, specular highlights sometimes show strong signs of onion rings within them.
The lens hood does feel and look like it can be scratched really easily.
I still do not like the idea of an exposed USB port.
While I think I might need some time getting used to its quirks (especially the field curvature), I am definitely pleased with the performance of the lens, and can see it being my primary workhorse lens with the 24-120/4S and 70-200/2.8S helping to fill in certain niche use cases.
After returning my rental unit I went on to purchase one copy for myself, and am definitely looking forward to working with the lens and trying out new combinations of set-ups to improve my workflow and quality of work!
Tamron 28-75mm f/2.8 Di III VXD G2 for Nikon Z-mount Announced
Tamron has just announced their latest Z-mount lens, the wide-aperture standard 28-75mm f/2.8 Di III VXD G2 lens.
Official press release here in English and Japanese.
According to reports and reviews of the E-mount version, this G2 lens has significant performance and handling improvements over the G1 lens that precedes it. And given that the G1 lens acted as the basis of the current Nikon Z 28-75mm f/2.8 lens, I would expect similar improvements of the new lens over the Nikon version.
With increasing lens prices throughout the board, I thought that it was a very refreshing breather to see this new lens being released in Japan at reasonable prices, similar to the current Nikon Z 28-75/2.8, and not that different from the E-mount version of the G2 lens at launch.
To be honest I was quite surprised about this announcement, since this lens was manufactured by Tamron under licensing agreement with Nikon, even though it would be competing directly with the Nikon Z 28-75/2.8, which is still an active model in the lens lineup.
I think there is no doubt that the Nikon Z 28-75/2.8 is based on the G1 version of the Tamron lens, but when it came in Nikon colors, there were many theories floating around the internet about who was the one actually building the lenses, and similarly predictions about the collaboration and agreement between the two companies started to find their way around too.
I do not think any one except for the parties directly involved in the negotiation and manufacturing processes would know exactly how the Nikon Z 28-75/2.8 was built.
So now that we have the 2 lenses in very similar price brackets, and assuming this G2 lens provides improvements over the Nikon Z lens similar to that in the E-mount camp, image quality and AF performance would definitely favor this new G2 lens, making the current Z 28-75/2.8 a tough sell unless serious sales or cashback campaigns are put in place to move them.
If not for pricing difference, I guess the only reasons one could still consider the Z 28-75/2.8 would be:
Preference over the Nikon-styled rings and barrel material, over the Tamron-styled rings and barrel material
Nikon’s SIC lens coating vs Tamron’s BBAR lens coating
Nikon’s weather sealing vs Tamron’s weather sealing
Being able to update the lens directly via camera body (Nikon) vs being able to update the lens directly via USB-C (Tamron)
Nevertheless, the launch of this lens also set an important precedence - it shows like Nikon does allow third party lens manufacturers to license lenses even if they are direct competition to Nikon’s own offerings.
This would mean that until now it has been the lens manufacturers who are unwilling to build things in the Z-mount, rather than being restricted by Nikon.
Anyway, time to go back to my previous post to add a little edit in the available standard zoom lenses for the Z-mount.
