About this item:
By connecting the USB cable to a computer, the SIGMA USB DOCK enables photographers to update the lens firmware and customise features of the lens to their requirements. The adjustment is processed with specially designed software, SIGMA Optimization Pro, which is available as a free download from Sigma’s website.
Users will be able to update lens firmware, ensuring their lens is never “out of date”. Fine focus adjustments are also possible at varying positions of the lens’ focal range and zoom positions ensuring the focus matches your camera precisely at every zoom and focus position.
Sigma’s “Sport” lenses also allow extra further customisation of the AF speed, Optical Stabilisation and Focus Limiter position.
Customisation for Art, Sport and Contemporary lenses: Focus Adjustment Settings: 4 Categories of customisation for fixed focal length lenses. 16 Categories of customization for zoom lenses (4 options for focal length) x (4 options for shooting distance).
Customisation for Sports lenses: AF Speed: 3 adjustment modes. Focus Limiter: Customize auto focus range. OS: 3 adjustment modes.
This USB Dock is only compatible with Sigma’s latest Global Vision, A (Art), S (Sport) and C (Contemporary) lenses. A full list of compatible lenses can be found on Sigma’s website.

5.0 out of 5 stars An inexpensive but invaluable addition for your newer Sigma lens(es).
I bought this to calibrate the superb Sigma 50mm F1.4 DG HSM Art Lens for Canon. It's very easy to use and the software (at least on MacOS) is also straightforward. Having sampled the quality of Sigma Art lenses, I anticipate buying more, which makes the dock a really useful, cost-effective purchase.It's great to be able to fine tune your lens but also to update its firmware, as well as making other tweaks (configuring full-time manual focus and its sensitivity in the case of the 50mm).When I initially thought of acquiring this I wondered how much it would cost but was very pleasantly surprised; great value.Until consumer technology changes calibration is always going to be hit and miss (i.e. you have to keep tweaking via the dock and trying it on-camera) but that's the nature of the task. Tip, get one of these: DSLRKIT Lens Focus Calibration Tool Alignment Ruler Folding Card (pack of 2).

Works perfectly, easy to use and great quality
4.0 out of 5 stars Useful addition for compatible lenses
Using this on a Sigma 150-600 sport. No software provided - has to be downloaded from Sigma's site (best way in my opinion for any new piece of software or drivers), but easy to download & install. Software for this is basic but usable (automatically checks for firmware updates for both dock & attached lens when lens connected) - hopefully new features will be added over time, software also provides information not provided on lens box or lens (needed the serial number for this lens for my camera insurance - nothing on box or lens, but showed up on the home page of the software). Device itself has a plastic (yet robust) feel to it, provided cable is reasonable length (have been able to use this on my desk without the need for an extension cable or replacing the cable with a longer 1 (unlike some other peripherals I have) and has a solid feel when connecting the lens. Overall a good addition if you have a compatible lens.
5.0 out of 5 stars Vital for adjusting Sigma Lens settings
Sigma have upped their game in recent years, their lenses are on a par - if not surpassing - some original manufacturer's offerings. This USB dock is really easy to use and enables the user, through the Sigma app, to update firmware or change settings of their lenses to suit their needs, such as focus distance limiting or focus micro adjusting.For some lenses it's possible to change the focus speed/priority if required also.The app can be downloaded free from Sigma's website and, once the dock is attached to the lens mount and plugged into a usb socket, it will read the lens and enable adjustments to be made.Certainly worth having if you own a number of sigma lenses.
5.0 out of 5 stars This is a worthwhile investment
OK, so you will probably only use this a couple of times and then it will sit in a cupboard somewhere plus calibrating your lens is really tedious... but I've spent an hour and a half calibrating my 150-600 Contemporary and it's gone from a pretty good lens for the money to a real amazing lens for the money!If you are planning on buying a Sigma lens, especially a super telephoto where the Depth of Field is so shallow that focusing is absolutely critical, I would say you should definitely budget for the cost of the USB dock as well.Don't forget that you will also need a Lens Focus Calibration Tool - I bought the Maxsimafoto one as I couldn't see the point paying more than the price of the dock for the DataSpyder - it did the job. You also need two tripods (one for the camera and one for the calibration tool).There are lots of YouTube videos on how to do this but all you really need to know, and which doesn't seem very well documented, is that, for a given focal length at a given distance, if the lens is focusing behind where it should, you give it a negative number and if it is focusing in front of where it should, you give it a positive number. 4 focal lengths, 4 distances so 16 test shots. Adjust and repeat until you get it spot on - took me about 4 repetitions until it was right.My one tip is to do the calibration on a cloudy day (assuming you are doing it outside) as glare makes it harder to read the calibration scale in your shots and under-expose by a stop because that scale is very bright.Buy one (or borrow one).
5.0 out of 5 stars Nice to be able to update firmware and change autofocus accuracy for supported SIGMA lenses
Nice to be able to update firmware and change autofocus accuracy for supported SIGMA lenses, although the lens I bought tyhis for already had latest firmware, I will keep so I can fine turn the focus distance of my SIGMA lens.
5.0 out of 5 stars Works!
Works as it should. Bought to update firmware on Art lens 24-105 F4

Utilissimo
Strumento fondamentale per aggiornare e gestire gli obiettivi Sigma. Attenzione ad acquistare il modello con l'attacco dei vostri obiettivi. Nessun problema nell'utilizzo, un pochino più complessa la fase di regolazione AF, ma per questo ci sono validi tutorial video. Prezzo ragionevole.
