Firmware Friday: Quick fixes for just-launched Pentax K-70; Sigma solves Nikon D500 lens compatibility


posted Friday, August 12, 2016 at 8:56 PM EDT


Firmware Friday is short and sweet this week, with updates for one camera and three lenses from Pentax and Sigma respectively. We'll jump right in with the update for Ricoh's just-launched Pentax K-70 DSLR first of all, and then come back to Sigma's lens firmware, which is intended to resolve issues when used with the Nikon D500 camera body.

Pentax K-70

Firmware version 1.10 for the Pentax K-70 makes two main changes in the launch firmware for the DSLR, which only just began shipping. With the new firmware installed, you'll be able to change the ISO sensitivity between frames in multiple exposure shooting. Improvements have also been made in preparation for the launch of the new HD PENTAX-DA 55-300mmF4.5-6.3ED PLM WR RE lens. And as Ricoh usually does, it has also suggested that the firmware may contain other unstated tweaks, noting simply that it has "improved stability for general performance".

Sigma 17-70mm, 18-300mm and 35mm

Sigma, meanwhile, has issued new firmware for three lenses: The 17-70mm F2.8-4 DC MACRO OS HSM C013, 18-300mm F3.5-6.3 DC MACRO OS HSM C014 and 35mm F1.4 DG HSM A012. In all three cases, the new firmware is applicable only to the Nikon-mount variants, and aims to resolve a problem with underexposure when shooting on the Nikon D500. The new firmware for the 17-70mm and 35mm lenses carries version number 1.03, while the 18-300mm update bears version number 1.01. To get the new firmware, install and run SIGMA Optimization Pro version 1.3.0 with Sigma's USB Dock accessory.
