The Samsung NX Lens Firmware v01.10 is applicable to the company's 30mm f/2.0, 18-55mm f/3.5-5.6 OIS and 50-200mm f/4-5.6 ED OIS lenses. The sole listed change is that the firmware is said to improve autofocus accuracy. Detailed instructions on upgrading the firmware can be obtained by reading a PDF document on the Samsung Electronics website, but briefly the process involves copying the firmware to a flash card, then placing the card in the camera, attaching a lens, powering on and initiating the upgrade through the camera's menu system.
As well as the updated lens firmware, which is a tiny 73KB zipped download containing all three updates, Samsung has also released a download of the initial firmware version for the NX10 camera body. The NX10 camera firmware v01.00 is a 4.5MB zipped download, and is also accompanied by a PDF instruction document. Both firmware update zip archives can be found on the Samsung Electronics website.
