    The Sigma 17-70mm F2.8-4 Zoom I recently purchased for my Canon SL1 focused in front of the viewfinder's indicated focus points. I had the choice of sending the lens and camera body to Sigma for adjustment, or doing it myself with the USB Dock. The Sigma USB Dock worked as advertised to adjust the focus points to the focus points indicated in the camera's viewfinder. This Dock only works on a few select Sigma lenses. See the Sigma website to see which lenses are supported. I would recommend buying only the supported Sigma Lenses as the others will not allow user adjustability with the Dock. Just download the free operating software from Sigma. The software is very easy to use. It provides four focus distance ranges at four different focal lengths. This equates to 16 adjustment points. The adjustments on my lens varied from each other at the various points so the number of adjustment points are very necessary. The results of the adjustments can only be verified by taking test pictures and most probably further adjusting to fine tune the focus. It is a time consuming process, but offers the very real potential of better focusing than that provided by sending the lens to Sigma for adjustment. After all, how much time will they spend on your lens, and will you have to send it back again if it needs further adjustment? The Sigma USB Dock is Highly recommended!

            I used this with my 30mm f1.4 ART which was front focusing. Fixed the issue for 90% of the shots taken. There are 4 different setting for adjusting focus through its focus range. While very helpful, some focus distances cant be adjusted.

            Must have if you own a Sigma Art lens

            Comments about Sigma USB Dock for Canon Lenses:

            I purchased this to apply firmware to the Sigma 18-35. Went smoothly. Great tool to keep your lens up-to-date. And for that me that's a big deal since the latest firmware to the Sigma 18-35 makes the dual pixel AF on the C100 even better!

            I wish there was a way to apply the firmware to the lens through the camera body instead of buying this. But that is probably too much to ask and only works on Panasonic bodies and lenses like on my GH4.

                Being able to fine tune and update my sigma art lens is a beautiful thing. It saves manual focus time and gives me a sense of control that I've never had over the piece of glass on the front of my camera. This is a great tool and, while sigma's art lenses are the some of the best I've ever used, this takes them to a new level.

                    Comments about Sigma USB Dock for Canon Lenses:

                    I used this for the 30mm prime "Art" lens to adjust focus so I can't testify to the other functions used on the "Sport" lenses. The quality seems solid. I had to disconnect and reconnect several times to get the focus adjusted and it never threw an error. Sigma provides a URL to download the software. The Mac software worked just fine. It's a little non-intuitive at first when you first connect the lens and the adjustments button is grayed out, you might think there is something wrong. But after a few seconds, it polls the lens and activates the button. Just would be nice for the software to tell you what it's doing so you're not thinking "hmm, what's up" while it's doing whatever it's doing--maybe checking for firmware update. That and maybe some instructions to tell you to click on the appropriate focal range to make adjustments would be the only things I would change. That and maybe "Save Changes" instead of "Rewritting" for the button that saves the changes you made back to the lens.

                              Everything about this product works as it says. However, there aren't really tutorials out there on how to test your lens for autofocus issues. It's a lot of trial and error. I'd love to see a video series from Sigma showing how they would test a lens and use the dock to correct it.

                              This little adapter works like a champ, it pet me adjust the focus very precisely on my 35mm 1.4A lens. I just wish I could change the speed of the focus like you can do with their 120-300mm sports lens. Other than that I recommend it!

                                        This is a great dock. It comes with everything (instruction, manual, warranty card) and it is also made in Japan. It works great. However, on the Sigma 35mm 1.4, I find that it doesn't have all the distances available. I think that it would be better to have more options to adjust at more distances. Atm, there are only 4 distances and I find it to be very limit. Some people would argue that they are happy with it since their lenses do not need more than that to adjust. However, in my case, I need to adjust my lens at 1m and 2m and I don't have that option. I don't really need to adjust it at MFD(0.3m) and 0.4m. Don't you think that 0.3 and 0.4m are so close together? If this lens is for street photography, 0.6m, 1m, 2m and Infitini would make more sense. If there are only 4 spots, then please let the users to pick what distances suit them the most. But overall, this dock is worth more than what it costs. Seriously. It has its limitations but I still give it a solid 5 stars. Good work Sigma, keep it up.

                                            You have to do some iterative shooting and reviewing to figure out what direction and by how much to adjust the base settings.

                                              Comments about Sigma USB Dock for Canon Lenses:

                                              I bought this USB dock along with a Sigma 35mm f/1.4 DG HSM Lens for Canon. Considering how critical precise focus is for large aperture lenses I wanted to be able to fine-tune focus characteristics at multiple distances, which isn't possible with camera micro-focus adjustment. As it turns out, the 35 f1.4 focuses very accurate on my 6D and no adjustment is needed at this point. However, I used the dock to update the lens firmware to the latest version and I am glad to have it for use with other bodies and lenses in the future.

                                              The dock is made of good quality plastic and mounts very snugly to the lens. A high quality micro-USB cable is also included, but note that the software (Sigma Optimization Pro) is not included and must be downloaded from the Sigma web site. Considering how often software updates are made this is probably a sensible cost savings.

                                              The software installed quickly on my Windows 7/64bit system and was fairly easy to use. I managed to update the firmware on the lens in a few minutes without incident; however, as other reviews have mentioned the software help and information in dialogs are a little sparse (version 1.0 software). So I found the software functional, but hope Sigma revises it to convey more information (e.g. firmware upgrade notes and more help) in the future.

                                              All in all I'm happy I purchased the dock, but it may have been more prudent to wait until I had a Sigma lens that need adjustment before spending the money.

                                                Comments about Sigma USB Dock for Canon Lenses:

                                                I recently bought a Sigma 18-35mm f/1.8 Art lens and learned that it is compatible with this USB dock for customization. I've read some reviews about it and wanted to try it out.
                                                In order to use this dock, I had to go to Sigma Global Vision website to download 'Sigma Optimization Pro' software. Installation and usage of the program was very easy and the software provides detailed instructions. The same can be said for calibration process from docking your lens to rewriting focus adjustments were easy and convenient. The USB Dock worked as it was advertised. With this dock, I could micro calibrate the focus on different focal length by adding or subtracting modifiers. The software provides neat and easy to follow graphic interface, so anyone can use this product. Since my particular lens does not have Image Stablizer, I cannot say much about how the dock would modify IS, but having that ability to further customize your lens is something very new to me. I find Sigma products are becoming more innovative and revolutionary nowadays. I am very happy with my new 18-35 lens and this USB dock. I would highly recommend this product for those who use compatible lenses.

                                                    If you have a camera that does not have micro adjustment then this is what you need for your new sigma lenses. I've used it with my sigma 35mm to calibrate it for my t3i since it used to front focus a bit on longer distances. Additionally to calibration you also get to update the software on on your lens. No more sending your lenses to sigma and waiting for calibration. You can do it in your home in the matter of minutes. Loving it!!

                                                        I was having a lot of focus issues with my Sigma 30mm 1.4 prime lens. This dock was very helpful in sorting out those issues. I would suspect this dock would be even more handy with a zoom lens.

                                                        It would be really cool if this dock came with a calibration chart of some kind. Even just a piece of paper with a guide on how to properly calibrate a lens.
