It enables firmware updates and detailed customization of autofocus parameters, including focus position, AF speed, and focus limiter settings, via the free Sigma Optimization Pro software compatible with Windows and Mac. Ideal for Art, Sport, and Contemporary lenses, this dock ensures your gear stays cutting-edge and perfectly tuned for professional-grade performance. ## Description 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 Users will be able to update lens firmware, ensuring their lens is never “out of date”.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. Review: First Impressions, Great bit of kit and must have for Sigma 150-600! - First day using it I immediately attached the dock to my Sigma 150-600 as I've been a little skeptical about the focus speed and accuracy. I say accuracy, but it depends on the situation and a lot of camera settings can have affect on the final image. So as soon as I attached the dock and loaded up the software it said there was new firmware for the lens, brilliant, exactly why I purchased the dock, bearing in mind I only purchased the lens July 2018. I also set up my C1 and C2 settings. C1 - Priority AF focus for quick wildlife shooting (which is really quick now!) and Moderate view mode for Smooth Optical stabilizer. Then C2 I have set up for filming so, slower auto focus and moderate view again for OS if filming hand held. I haven't used the full focus adjustments yet, but will leave the Easy to use as 4 star as I have heard trying to get the correct focus settings if it's front/back focusing too much can be very tedious as you have to set up a tripod and fine tune each focal length. But for now I do not have Micro AF adjustments in camera so if it takes few hours and it works, then money well spent. Review: Works with SIGMA Art, Sport, and Contemporary Lenses - Useful if you own any of the new SIGMA ART (A), SPORT (S), or CONTEMPORARY (C) Lenses. I only own a couple of Prime Art lenses but anticipate buying more from the three ranges as they are so good. The dock allows micro adjustments to be made to focussing as well as firmware upgrades (i.e. as and when new cameras and systems are released from the likes of Canon and Nikon). Not much more to say. When connected to a lens the green light comes on but this is in the base and if you have it on a desk or table you cannot see it unless you pick the whole thing up. You do not need to have one of these but for the tekkie enthusiasts it is probably a must have. ## Features - For use with Sigma’s Global Vision lenses - Update lens firmware so your lens is never “out of date” - Adjust focus position to match your camera for precise auto focusing - Customise features including autofocus speed and focus limiter distances on Sigma’s “Sport” lenses - Free download of Sigma Optimization Pro, compatible with Windows and Mac computers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CBQ5YOS | | Best Sellers Rank | 8,821 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 32 in Camera Lenses | | Box Contents | Box contents: USB dock | | Brand Name | Sigma | | Colour | Black | | Compatible Devices | Sigma 35mm F1.4 DG HSM, 17-70mm F2.8-4 DC MACRO OS HSM / 120-300mm F2.8 | | Country of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (4,868) | | Global Trade Identification Number | 00085126878542 | | Hardware Interface | USB | | Item Dimensions L x W x H | 10.2L x 5.1W x 5.1H centimetres | | Item Weight | 65 Grams | | Manufacturer | Sigma | | Manufacturer Part Number | 878954 | | Model Number | 878954 | | Number of Ports | 1 | | Smart Home Compatibility | Not Smart Home Compatible | | Total USB Ports | 1 | | UPC | 085126878542 | | Unit Count | 1.0 count | | Wattage | 2.5 watts | ## Product Details - **Brand:** Sigma - **Colour:** Black - **Compatible devices:** Sigma 35mm F1.4 DG HSM, 17-70mm F2.8-4 DC MACRO OS HSM / 120-300mm F2.8 - **Hardware interface:** USB - **Item weight:** 65 Grams - **Number of items:** 1 - **Number of ports:** 1 - **Product dimensions:** 10.2L x 5.1W x 5.1H centimetres - **Total USB ports:** 1 - **Wattage:** 2.5 watts ## Images ![Sigma USB Dock Canon - Image 1](https://m.media-amazon.com/images/I/71u1CdKAOzL.jpg) ![Sigma USB Dock Canon - Image 2](https://m.media-amazon.com/images/I/61an5kL1A+L.jpg) ![Sigma USB Dock Canon - Image 3](https://m.media-amazon.com/images/I/71g2CJnXQXL.jpg) ![Sigma USB Dock Canon - Image 4](https://m.media-amazon.com/images/I/71QoUeJYBnL.jpg) ![Sigma USB Dock Canon - Image 5](https://m.media-amazon.com/images/I/71ompxlaIwL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: There are 3 options; for canon lens, nikon or sigma lenses. So if I have the sigma zoom lens but the camera body is canon, which dock do I need?** A: The Canon Dock if you have a Canon camera. Check that the Dock will work with the Sigma lens you have. If its the 150 - 600 Contemporary or Sport you have it will work. **Q: Why do I need to update the firmware on a new lens** A: In truth you may never need to do this BUT if you change your camera body or want to modify the OS button effect on the lens then this will let you do it. NB it only works with certain Sigma lenses (C and S, and probably A, versions only I think). Not expensive but probably an item a camera club should have in their kit. **Q: Are there any step by step tutorials on how to correct the autofocus in english, using the usb dock?** A: yes to you tube **Q: wich sigma usb dock i should buy for a sigma lens canon fit?** A: https://www.amazon.com/Sigma-USB-Dock-for-Canon/dp/B00CBQ5YOS ## Customer Reviews ### ⭐⭐⭐⭐⭐ First Impressions, Great bit of kit and must have for Sigma 150-600! *by S***M on 27 September 2018* First day using it I immediately attached the dock to my Sigma 150-600 as I've been a little skeptical about the focus speed and accuracy.

I only own a couple of Prime Art lenses but anticipate buying more from the three ranges as they are so good. The dock allows micro adjustments to be made to focussing as well as firmware upgrades (i.e. as and when new cameras and systems are released from the likes of Canon and Nikon). Not much more to say. When connected to a lens the green light comes on but this is in the base and if you have it on a desk or table you cannot see it unless you pick the whole thing up. You do not need to have one of these but for the tekkie enthusiasts it is probably a must have. ### ⭐⭐⭐⭐ Useful addition for compatible lenses *by C***R on 28 October 2015* 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. ## Frequently Bought Together - Sigma USB Dock for Canon - Sigma 150-600mm 5-6.3 Contemporary DG OS HSM Lens for Canon - Altura Photo 95mm Lens Filter Kit - Multi-Coated UV Protector, CPL Polarizing and ND Neutral Density Filters + Case for Camera Accessories & Lenses --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/48040880-sigma-usb-dock-canon](https://www.desertcart.ro/products/48040880-sigma-usb-dock-canon) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-04*
