Sigma will release firmware update to fix AF issues with the Nikon D5300

Sigma reported AF issues when using their lenses with the Nikon D5300 camera. A new firmware update to address those problems will be released tomorrow. If your Sigma lens is not compatible with the USB dock, you will have to contact your nearest Sigma service center in order to get the update.

Information Regarding the Nikon D5300 Cameras

Thank you very much for purchasing and using Sigma products. We have found that the current firmware of our Nikon fitting interchangeable lenses may not work properly with the Nikon D5300’s OS and Live View Auto Focus functions. For those customers who own Sigma lenses in Nikon mount, we are going to provide a free firmware update service. Please note that all the products we dispatch from the factory will have the latest firmware.


Without the latest firmware, the OS and Live View Auto Focus functions do not work properly when it is used with the Nikon D5300.

Concerned Products

Nikon fitting interchangeable lenses that incorporate an internal motor.
* Firmware upgrade cannot be applied to the lenses that do not have an internal motor.
* For some discontinued products, we may not be able to offer the firmware update due to the discontinuation of related repair parts. Please contact your nearest authorized Sigma distributor for the further details.


For those customers in need of the latest firmware, we are going to provide free firmware update from November 20th. For discontinued products, please contact your nearest authorized Sigma distributor for the further details. For lenses that are compatible with the SIGMA USB DOCK, it is possible to update them via SIGMA Optimization Pro.

Update: the firmware update can be downloaded here.

  • AF problems with a Nikon!? That’s impossible!

    • groucher

      It’s not an AF problem with a Nikon camera – it’s with the Sigma lens. If the problem was Nikon’s, there would be incompatibilities with existing Nikon lenses – but there aren’t.

      • It was obvious sarcasm.

        I thought.

        • Whoosh… That was the sound of your post sailing past the listeners… LOL…
          Though it pains me to have to do so, I have to disclaim with a smilie or even a full statement anything I say which I deem to be humorous just like I do when writing here at home in Japan, since innate humour gland hormone production levels appear to be at about the same levels.

  • French Fries

    The question is… does Sigma want to sell more USB docks and will we see this more often from Sigma in the near future?

    • Mike

      1. The dock is less than a lens filter and can be used on multiple Sigma lenses. 2. Yes, companies want you to buy their products. 3. If Nikon sold a dock*, it would likely be multiple hundreds of dollars.
      * They would never because their lenses are perfect.

    • I think Sigma will sell more USB dock *Lenses* due to Nikon’s “shifting goalpost” approach to modern consumer level camera firmware design. This may end up applying to third party batteries, too.

  • skaarj

    At least Sigma stands behind the customer and is willing to fix the problem instead of denying the problem. Another company would just update the lens and add a 10 to it.

    • Ronan

      Hahaha bitter much? D600 problem fixes itself after a few hundred shots. You also get free cleanings for it.

      • Mansgame

        WRONG! It never goes away. After about 3 or 4 cleanings the dust becomes less but doesn’t go away. Then when you get a new shutter, it goes back to square 1. Are you a Nikon Employee?

      • Aldo

        lol “few hundred shots”

      • skaarj

        “Free” with what shipping cost? My returned D600 actually did get better with the dust after 800 clicks then the oil splatter began. You could void the warranty and clean it yourself. But you still have to buy the expensive solution and product.

    • bob2

      Good luck with Sigma trying to fix that same lens in a couple of years when it’s been discontinued–will never happen. I have an older Sigma AF lens that consistently underexposes between 1/2 and 1 stop depending on the camera. I tried another copy that misfocused badly (but only on newer dslrs). And another with a rubber coating that had become sticky and gummy. All three copies of the same lens, each with different problems–and it’s a mid/late 1990’s lens, so it’s not ancient. Sigma won’t/can’t repair those issues. Also try finding lens hoods or other parts–it’s impossible because Sigma doesn’t support its older stuff (Tokina and Tamron are the same). I know I can still find repair parts for most of my Nikkors, even the older ones.

    • Dpablo unfiltered

      That’s the weakest comment I’ve read all day. Both companies are good but the one company will not be able to fix it’s product more than a year after it is superseded with another and makes it’s products assuming that it knows everything about what is coming down the pipeline when it doesn’t. The real compatibility issues with Sigma have been with Canon. There are a lot of old lenses that will work with any mount except Canon.

      • skaarj

        I believe you understand what you think I said but Im not sure if you realize that what I said is not what I meant?.

        • Sure, I know he believes he understands what he thinks you said, but I’m not sure he realises that what he read wasn’t quite what you meant.

  • Jack S

    Sigma don’t support all operating systems with their USB dock, so that sucks for quite a lot of us. It’d be best if they just released their firmware as open source. That way it’d be more reliable, less buggy, problems can be fixed almost instantly, and Sigma’s reputation will go way up.

    • Ken Elliott

      Here’s the catch – someone mods the firmware, causing your lens to brick (become non-functional). It lands at Sigma, with customer complaints. This is not uncommon with other devices (modified Android builds) and is a legitimate concern.

      But I might be a nice thing if the INSTALLER was open source. Then you could use the USB dock with Mac, Linux, BSD, etc.

      • Agreed. Sigma would see no significant gains for the increased liability they would face. I don’t see it happening, but again, there is always the possibility of reverse engineered hacks, ala Nikon DSLR Firmware. Some of which have shown real benefits.

    • Imagine a forked firmware written by non Sigma lens specialists and then a fork of the fork with patches added from, say, another popular version of the firmware written by some employees of Sigma who felt that the official Sigma firmware lacked some particular optimisation of a particular feature or other.

      Now faced with about four or five potential firmwares for your lens, which one would you choose and whose opinion would you trust regarding the firmware working as advertised for your use?

      Moreover would you entrust the safety of your $1500 purchase to an non-waranteed firmware or would you play it safe and download the official patches from Sigma?

      Open source… While I’m a devout fan of it in certain situations, IMHO I don’t believe this is one of them.

  • Eta76

    Would the firmware update also solve the Nikon D7100 (focus) problems?

    Nikon keeps “bricking” new DSLRs with their dumb firmware “upgrades”. I already had to send my Sigma 10-20mm and Sigma 50mm 1.4 HSM to the Sigma service centre to make them work on my D5100 last year, now again with the D5300 ???

    Sigma makes excellent products and Nikon is simply scared of Sigma eating their lens market. Look at the 8-16mm, best DX UWA, 50mm 1.4 and 35mm 1.4 HSM, best FF primes available in those focal ranges. Not speaking of the new 18-35mm 1.8, a revolutionary lens – Nikon should thank Sigma to stimulate the market and bring new customers to buy their DSLR cameras instead of “bricking” their firmware constantly to fight competition.

    • Bayou Bill

      Sigma does seem to have stolen some attention away from Nikon with their newer lenses, and their pricing would most likely appeal to people on a budget, such as D5xxx owners. Are you suggesting that Nikon has retaliated by introducing something in the 5300 firmware that they knew for sure would cause problems with the Sigma, to scare people away from that brand? (Just wondering)

      • skaarj

        Maybe. My Sigma 17-70 C. Is the sharpest, fasting focusing and well constructed lens I own. I cashed in my nikon primes after testing and using this lens for a couple of weeks. I previously owned the 35mm 1.8 dx, 50mm 1.8 d, and 85mm 1.8 d. I could not get these lenses sharp until 3.5 even with fine tune on my D7000. My Sigma 17-70 C is perfect without any fine tuning.

    • Bayou Bill

      Peter, did you delete my response to Florian Hossfeld? If so, why?

      • Bayou Bill

        Okay, it has reappeared. Sorry to bother you.

        • Sometimes it may take some time for the comment to show up.

      • I did not delete any responses today, let me check the spam folder.

      • Florian Hossfeld

        I dont see it anymore either, my email kept your copy – Bayou Bill wrote (nice hint to the nes game btw) “Sigma does seem to have stolen some attention away from Nikon with their newer lenses, and their pricing would most likely appeal to people on a budget, such as D5xxx owners.

        • Florian Hossfeld

          so let me answer – yes – I do think that Nikon purposely wrote a coding line into the firmware to block some compatibility (live view AF) with Sigma lenses. Sigma represents a treat to Nikon’s lens market, and unless Tamron signed some kind of agreement with Nikon, they will be next. The fact that Nikon changed the coding line twice only for Sigma lenses (first on D5100-D7000-D7100-D3200-D600 models now with the D5300 and probably next DSLR) proves it.

          • Dpablo unfiltered

            Let me tell you that is a Canon thing.

    • John Schroeder

      Then why do Tamron lenses work perfectly?

      • orpickaname

        Because Tamron is not yet as much a threat as Sigma already is?

    • While I understand and agree with your sentiment, I take issue with your use of the word “bricking.”

      Bricking permanently reduces an electronic item to the functional equivalent of your standard, common-or-garden brick.

      Note the equivalence to a brick. A brick cannot, ever be made to take photos, no matter what, hence nor can a bricked camera.
      A more straightforward way would have been for me to point out the *permanently* bit in the above statement.

      If an electrical appliance or electronic gadget functions even slightly or can be made to function once more without replacing parts, it is not bricked, but merely temporarily disabled.

      In your case, the DSLR is not bricked, since without touching the camera, they can (theoretically) be made to work again.

      Were you to have connected said lenses to the aforementioned brick, you would almost certainly have still been without photos today.

      I refer you to the “urban dictionary”, who IIRC made it “word of the day” some years back.

      … I’ll get me coat. 😉

  • 103David

    I still say this color scheme dresses the camera just like Captains Picard and Janeway.

  • Gerald Eisen

    Just received my D5300 and my Sigma 150-500 works perfectly, just as it did on my D5200

    • Toshik

      Also think of buying D5300, but now hesitate because i have several sigma lenses which can’t be easily updated with usb dock at least now and i don’t have sigma center in my town to hand in for update… so looking for more feedback.

    • John Baxter Photography

      Why would you upgrade from D5200 to D5300? Waste of money fool.

      • Gerald Eisen

        I did not upgrade, I added as I need two bodies as I shoot wildlife and need both for two different lenses

        • Toshik

          Can you upload video made with your 150-500 on D5300 where it is clear that AF is working flawlessly?

          • Gerald Eisen

            I do not shoot video so I can’t answer that question for you. Sorry

            • Toshik

              That’s a pity, cause video usage maybe totally screwed up.

      • By the way you are writing, I can tell that you either:
        A) know him personally, are intimate with his shooting style and are fully aware of his needs and/or those of his studio,
        B) are a dick.

        • Jorge

          I vote “B”

  • Toshik

    UPDATE: Sigma fixed it for new lenses:

    35mm F1.4 DG HSM A012 NIKON
    17-70mm F2.8-4 DC MACRO OS HSM C013 NIKON
    30mm F1.4 DC HSM A013 NIKON
    18-35mm F1.8 DC HSM A013 NIKON
    120-300mm F2.8 DG OS HSM S013 NIKON

    via firmware update through usb dock.

    Still unknown how to fix older lenses without sending them back to factory to upgrade firmware.

    Accroding to recent rumors they’re planning to make usb dock compatible with older lenses with HSM motor. Maybe with it sometime we will be able to upgrade the older lens firmware with it.

    By the way, does AF properly work in Live View (video) on D7100 and D5200 with older Sigma lenses like 17-50, 10-20, 18-200? Asking cause it’s influence on my decision what body to buy.

  • Well it appears I have a focusing issue with my 12-24 sigma & D3200, only in live view. It just does not focus. But I will try again tomorrow in good light (outdoors).

  • foukographer

    Hum… So what I don’t get is… If Sigma can update the firmware on NIKON lenses…maybe it should also be able to adjust parameters (finetune focus, etc) on these lenses?
    As far as I know, the dock can only be used for the Sigma Global Vision lenses but who knows, maybe that dock will be able to work with Nikon lenses later, which would be pretty awesome.

    I think a lot of unforgiving Nikonites are posting here in quite unfair and unreasonable terms. I got my superwide zoom in 2010 and at the time paid just under £370 for it – if I had bought the nikon equivalent at the time we were looking at over £700. Now, the value of both lenses will depreciate over time, and as we have seen with Nikon, eventually a new range of bodies will appear, rendering the current lenses dysfunctional in one respect or another (autofocus etc) more likely than not. So, I am very very happy with the Sigma, it is pushing six years old now, and Sigma have just booked it in for a firmware update so that live view autofocus and shoot will function fully with my recently bought D5500. All this for the princely sum of £5.00 plus the cost of my posting it into them here in the UK.

    I wonder what kind of money Nikon would be looking for, had I bought one of their own brand lenses, and finding it needed such an update? I recall when I bought a travel zoom (Nikon 18-140 VR) two years ago, I found that the D5200 body I had, did NOT support distortion correction in-camera, and I wrote to Nikon immediately asking when a firmware fix for the D5200 was to be released to support this feature. They replied that there were NO PLANS to provide any fix for this ‘kit lens’ despite the fact that in many countries, they started shipping a version of the ‘kit’ incorporating a D5200 WITH the 18-140mm VR!!!!

    I have the Sigma 105mm VC Macro, and it whops the pants out of the Nikon 105mm Micro (macro) and I also have the Tamron SP Di 70-300 VC telephoto, which is also much sharper than the Nikon 70-300 VR and has a vastly superior VR system, so, don’t be seduced by Nikon brochures, they are not lens specialists, they are camera manufacturers who also make lenses, microscopes, and photocopiers, and their history with the faulty D600 should have taught us all we need to know about customer service.

    Sigma can teach them an awful lot about that, for sure!
