We have found that the SIGMA 17-70mm F2.8-4 DC MACRO HSM | Contemporary PENTAX does not function properly when the image stabilizing system on the camera body is used.
For those who own the lens, we are going to provide the firmware update free of charge.
Please note that all lenses shipped from our factory from now on will have the latest firmware.
We appreciate your continued support for our company and products.
