To book a Sigma lens calibration service of 1 lens to 1 camera including the firmware upgrade (if applicable and configuration of User 1 and User 2 settings) please check if your lens is compatible.

Perhaps the QC out of Sigma isn't as good and this is why they need to do this but I for one am happy with the results at this time. The cost of this service is an additional £10.00 on top of our normal calibration prices. Hi All,In this video, I explain how to calibrate your sigma lens using Sigma USB dock, calibration software and a budget calibration tool I bough from amazon.

Without the dock this would not have been possible. I didn't bother testing all focal lengths using focal on the D500 however even without it the lens is performing much more consistently.

I then put the lens on my D500 and if memory serves correct Focal gave me an AFFT of +2 or +3 at all 600mm focus distances. For use with SIGMA Global Vision lenses UD-01 for DSLR lenses UD-11 for mirrorless (DN) lenses Update lens firmware on all compatible lenses Adjust focus position, AF parameters, OS settings, etc. After all was said and done I was left with an AFFT of -1 on my D850. I did this 3 or 4 times until Focal was giving me the same final AFFT for each focal length at each distance. I then retested using Focal to see what it gave me for each length. I believe I used the number that Focal gave me and doubled it as the base number for the dock lengths. I then adjusted the lens using the Sigma dock at each focal length and focus distance. I ran through Focal at the same focus distances that the Sigma dock allows you to tune at as well as all the same focal lengths.

I finally set aside a full afternoon to do tests using Focal and in body AFFT. please contact your nearest authorized subsidiary / distributor of SIGMA. I was having a heck of time getting consistent and stable readings using in body AFFT of my D500 and D850 and the Sigma 150-600 Sport.

Have 85/1.8G (got used) - focus is spot on with no correction.Like Sushi Eater I had some issues with my Sigma 150-600 Sport although mine didn't have to go back to Sigma. IOW the setting close to 2 meters set it for 3 meters or more and the second setting instead of 1.25m set it for 2m. The AF speed, focus limiter and OS function are also customizable for Sports lenses. The adjustment is processed with special software (SIGMA Optimization Pro). The only other thing I could think off is to push all settings farther apart. SIGMA USB DOCK enables photographers to update the lens firmware and adjust parameters such as focus. Still think, that it is better then Sigma 35 Art in terms of reliability, but you have to move closer. At 800m you lens is already at infinity so no need to set anything. Of course this can be done on some cameras too, but if you tune with dock you will get tuning independent of the camera. Have 28/1.8G (got used) - focus is spot on with no correction. Another reason to buy Sigma USB dock is to make on your copy of lens fine tune the focus. Sold, because didnt know how it could be good on FX. Had 35/1.8G DX - bought new 2 year ago - focus is spot on with no correction with D7100 and D600 later. Had 50/1.8G (got used) - focus is spot on with no correction with D7100 and D600 later. Or may be that was me, who didnt managed the lens. Occasionally, mine was not very reliable at f1.4 in terms of focus, especially in lower light.

Yes, you can do that and you should do that, because yom may apply different corrections at different distances. I have corrected via usb dock "+14" at all distances, leaving the camera settings at "0". Used to have Sigma 35/1.4 Art with D600, corrected at + 14 at camera The +15 adjustment pretty much matches the setting I got when I was just messing around with the lens taking pictures of various items, so I am fairly happy that the Focal target and software has done what it was supposed to do. I therefore don't want to take a chance with a third lens which could be even worse that my current copy. Whether the problem is the test target not being ideal for testing focus according to the Nikon guidance on what can cause focus error, you are not following the test target guidance, or you have had 2 unacceptable lenses are separate issues.įocal lets you compare your lens with other uses who have calibrated their lens with the same software, and mine was reported as higher than average focus consistency and lower than average CA, so apart from the out of the box front focus, I seem to have picked up a good copy this time. What you do is up to you, but I would not accept anything that needed 3 never mind 15 as suitable for photography.
