For Sigma lens owners we are now able to offer a unique calibration service which goes beyond the methods offered by the camera manufactures. Canon recently offered the ability to calibrate certain Canon zoom lenses at both ends of the focal range, Nikon unfortunately only allow for one calibration setting to be applied.
Sigma allow, with the use of their dock, the ability to calibrate at different focal lengths throughout the zoom range. We have found this process can be very frustrating to set up and if undertaken is only applicable to the lens not the camera body.
Using our preferred software method we are able to offer a more accurate calibration system that is biased to the camera the lens is intended to be used with.
This facility is available with the following lenses
20mm F1.4 DG HSH
24mm F1.4 DG HSM
30mm F1.4 DC HSM
35mm F1.4 DG HSM
50mm F1.4 DG HSM
85mm F1.4 DG HSM
135mm F1.8 DG HSM
12-24mm F4 DG HSM
18-35mm F1.8 DC HSM
24-35mm F2 DG HSM
24-105mm F4 DG OS HSM
50-100mm F1.8 DC HSM
17-70mm F2.8-4 DC Macro HSM
18-200mm F3.5-6.3 DC Macro OS HSM
18-300mm F3.5-6.3 DC Macro HSM
150-600mm F5-6.3 DG OS HSM
120-300mm F2.8 DG OS HSM
150-600mm F5-6.3 DG OS HSM
We are also able to update the firmware of your lens and adapt the focus and image stabilisation settings according to your specific genre and preferences.
Note as of March 2016 Sigma have launched a firmware upgrade to the Contemporary and Sport series 150-600mm increasing focusing speeds by up to 50%. For a minimal fee we are able to update your lens accordingly.
This unique calibration can therefore yield the best professional results from your Sigma lens.

Please note – Test results – Before & After may not initially show vast improvements. This is often due to the fact the lenses do not always resolve the optimum quality when used wide open as in the maximum aperture. Significantly sharper images can be obtained by stopping the lens to a smaller aperture
If during the test, we find this to be the case we will record images at smaller images to demonstrate that sharper images can be obtained by taking comparison shots before and after calibration.
We also offer a lens optimum test in which we can identify the best aperture in which to shoot at (often referred as the lens sweet spot) and the point at which diffraction occurs.
As well as the Sigma Calibration service for an additional £10 we offer the same calibration and include a firmware update and user configuration. We will configure User 1 & User 2 settings (as in AF functionality and Optical Stabilizer settings) according to the user preferences be it Wildlife, Sport. Aviation etc.
These two additions are especially useful for those Sigma users who do not own a Sigma dock.
