I tried my old version lens (7 numbers in serial) also with another D7k body with same results. The Live view autofocus does'nt work with this old version lens. I think we should send post to Sigma that they would make a firmware update.

A histogram is a graph depicting the distribution of brightness values in the image. The horizontal axis shows the brightness level (from 0 to 255), with darker pixels towards the left side and brighter pixels toward the right. The vertical axis shows the proportion of pixels at each level of brightness.

By examining the histogram you can gauge the over-all exposure of an image. When the histogram is higher on the left side, the image is mostly composed of dark pixels, causing it to appear dark-either because the image is underexposed or because it is a dark scene such as night shot or sunset.

When the histogram runs off the right side, the image will have many white pixels-either because the image is overexposed or because it is a bright scene such as the beach or snow. A histogram with a fairly even distribution of pixel values usually indicates that the image is well exposed, with good contrast. However, the histogram distribution of a well-exposed image will vary greatly depending on the subject. In 2013 Sigma introduced our Global Vision lens line along with the USB dock, an accessory sold separately allowing you to calibrate the AF Data of any Global Vision lens. By connecting the USB cable to a computer, SIGMA USB DOCK enables photographers to update the lens firmware and adjust parameters such as focus. The adjustment is processed with special software (SIGMA Optimization Pro).

The AF speed, focus limiter and OS function are also customizable for Sports lenses. To find out more information, consult the. FLD ('F' Low Dispersion) glass is the highest level low dispersion glass available with extremely high light transmission.

This glass has a performance equal to flourite glass which has a low refractive index and low dispersion compared to current optical glass. FLD glass offers superior optical performance, equal to flourite, at an affordable price. ELD (Extraordinary Low Dispersion) glass has lower dispersion characteristics than SLD (Special Low Dispersion) glass, which Sigma has been using in its APO lenses (and some non-APO lenses as well) for many years now. It has other advantageous properties as well.

Please do not panic and do not return your lens. In the majority of cases, there is nothing wrong with your lens; each lens is manufactured in exactly the same way and adjusted on an optical collimator which is used to calibrate the lens, check if all elements are aligned optically and to set elements at the proper focus.

The issue of front and/or back focusing, most likely, comes as a result of the viewfinder focusing system which varies in each and every camera. This is a quick solution to this situation. If you are experiencing front and/or back focusing issues, we urge you use the “AF fine tune” or “Microfocus Adjustment in your camera’s menu to calibrate your lens to the camera. If this feature is not available in your camera’s menu we will ask you to send the lens to us and we will rewrite the AF Data to accommodate for the variation in your camera’s viewfinder focusing system; essentially, calibrating your lens to your camera. This will be done within a 48 hours of receiving your equipment in our headquarters; 15 Fleetwood Ct.
